Test Paper :2 Paper Type : Technical - Java Test Date : 10 April 2010 Test Location : Bangalore Posted By : Mythri 1) What is an object? An object is an entity, which consist of attributes, behaviors and qualities that describe the object.

2) What is a class? A class represents a collection of attributes and behaviors of object. It is the class from which individual objects created.For example:- Bicycle is a class that contain the following attributes Speed Gear

3) What is OOAD? OOAD stands for Object Oriented analysis and design. It is a methodology use to analyze, design and develop applications. It visualizes the class and the objects.

4) What are the advantages of OOAD? * Reusability * Maintainability * Increase the performance of the system.

5) What is Data Abstraction? It is a process of listing the essential features, without implementation details. Data abstraction is nothing but the extraction of the information which is required and ignoring the other information. 6) What is Data Encapsulation? Data encapsulation or data hiding is a function that keeps the implementation details hidden to the user. The user of the application is allowed to perform only limited task with the class members that are hidden.

7) What is the difference between data abstraction and information hiding? Abstraction mainly focus on the outside view of the object whereas encapsulation prevents the user from seeing the

inside view where the properties and behavior of the abstraction is implemented.

8) Why is java not 100% pure OOPS language? Java doesn’t support 100% pure OOPS concept, since it support primitive datatype like int, long, byte etc, these are not objects.

9) Qualities for a program to be 100% OOPS language? Encapsulation/Data Hiding 1. Polymorphism 2. All predifined types are objects 3. Inheritance 4. Operations performed through messages to objects 5. Abstraction 6. datatypes are to be objects.

10) What is early binding? Early binding or static type or static binding is assigning the value of the variable during design phase. Early binding instruct the compiler to allocate space and perform other task before the application starts executing.

11) What are the disadvantages of threads? o The main disadvantage of using thread is that it is operating systemdependent. It require to follow CPU cycle that various from system to system. o Deadlock occurs

12) Why is java case sensitive? Java is platform independent language. It is widely used for developing code which contains different variables and hence java is case sensitive.

13) What is singleton class? A class which can create a single object at a time is called class. The object is accessible by the java virtual machine. It creates a single instance for the class

14) Objects are passed by value or by reference? In java objects are passed by value. Since, the object reference value is passed both the original and the copied parameter will refer to the same object.

15) What is serialization?





It is a method which saves the object state by converting to byte stream.

16) What is externalizable interface? Externalizable interface controls the serialization mechanism. It consist of two methods readexternal and writeexternal. It helps to customize the serialization process.

17) What are the different types of inner classes? * Member classes. * Anonymous classes. * Nested top-level classes. * Local classes.

18) What are wrapper classes? Wrapper class represents a base class for the data source. It allows the primitive datatype to be accessed as objects.

19) What are the different ways to handle exception? * By placing the desired code in the try block and allow the catch block to catch the exception. * Desired exception can be placed in throw clause.

20) Is it necessary that each try block must be followed by a catch block? It is not essential that try block should be followed by catch block.

21) What is the difference between instanceof() and isInstance()? instanceof() is used to see whether the object can be typecast without making use of the exception. isInstance() is to check whether the specified object is compatible with the class that represent the object. 22) How can you achieve multiple inheritance in java? Multiple inheritance in java implemented in similar to the C++ with one difference the inherited interface should be abstract.

23) What is the difference between == and equals methods? ‘==’ is used to check whether two numbers are equal ‘Equals’ is used to check whether two strings are equal. 24) What are java beans? Java bean is a platform independent and portable. It helps



to develop code that is possible to run in any environment

25) What is RMI? RMI stands for remote method invocation; it enables the developer to create application based on java, in which the java objects are invoked by java virtual machine.s

Part 2

1. How does a try statement determine which catch clause should be used to handle an exception? When an exception is thrown within the body of a try statement, the catch clauses of the try statement are examined in the order in which they appear. The first catch clause that is capable of handling the exception is executed. The remaining catch clauses are ignored.

2. Is Empty .java file a valid source file? An empty java file is perfectly a valid java source file.

3. Is delete a keyword in Java? Delete is not a keyword in Java. Java does not make use of explicit destructors the way C++ does.

4. How many objects are created in the following piece of code? MyClass c1, c2, c3; c1 = new MyClass (); c3 = new MyClass (); c1 and c3 are the two objects created. The c2 is only declared and not initialized.

5. What will be the output of the following statement? System.out.println ("1" + 5); Output:- 15.

6. What will be the default values of all the elements of an array defined as an instance variable? If the array is of primitive data type then the elements of the array is initialized to default value. If the array is of reference type then it is initialized to NULL.

7. What are the different scopes for java variables? The different scopes for java variables are as follows:-



Local Instance Static

8. What is the default value of the local variables? When the local variables are not initialized explicitly the java compiler will not compile. And it will not initialize any default value for these local variable.

9. Can main method be declared final? The main method can be declared final with the addition of public static.

10. Does Java provide any constructor to find out the size of an object? There is no sizeof operator in java. It is not possible to determine the size of the object directly in java.

11. What is the Map interface? Map is an object which helps to map the keys to values. It is not possible to have duplicate keys. It is essential that each key should map to a one value.Three Map implementations areHashmapLinkedHashmapTreemap

12. What is collection Views? Collection view is a metho that is used to view map as a collection. This can be done in three ways:-ValuesKeysetEntryset

13. What is multimaps? Multimap is also like map which map key to multiple values. But there is no separate interface for multimap in Java since it is used quiet often. It’s much more simple to use map whose values to list instance as a multimap.

14. What is the SimpleTimeZone class? It is a subclass of Time zone which represent time zone that could be used with Gregorian calendar. It doesn’t handle any changes.public class SimpleTimeZoneextends TimeZone



15. Is &&= a valid Java operator? no &= is a valid operator not &&=

16. Is "abc" a primitive value? Abc is a string object it is not primitive value.

17. What modifiers can be used with a local inner class? Some of the modifiers that can be used in the local inner class are as follows:- Final Abstract Static modifier

18. Can an unreachable object become reachable again? An unreachable object becomes reachable if the objects finalize() method is invoked, the object performs operation that causes the object to accessible.

19. What happens when you add a double value to a String? When double value is added to the string it becomes a string object.

20. What is Layout Managers? It is an object that implements LayoutManager interface and also determines the position and size of the components within a container. Some of the task associated with layout manager are as follows:- Adding space between components Adding components to container Setting up layout manager

21. What is a compilation unit? A compilation unit is composed of two parts: an interface and an implementation. The interface contains a sequence of specifications, just as the inside of a sig … end signature expression. The implementation contains a sequence of definitions, just as the inside of a struct … end module expression

22. Which package is always imported by default? “Java.lang” is the package that imported by default.

23. What is numeric promotion? Numeric promotion is a conversion of numeric type of



smaller to a larger numeric type,so that integer and floating-point operations may take place. In numerical promotion, byte, char, and short values are converted to int values. The int values are also converted to long values, if necessary. The long and float values are converted to double values, as required.

24. Which arithmetic operations can result in the throwing of an ArithmeticException? Integer / and % can result in the throwing of an ArithmeticException.

25. What is the ResourceBundle class? It contains locale specific objects. If a program requires locale specific resources then the program can load resource bundle that is appropriate for the current user. Advantage:- Make it localized, and can be translated into different languages. Modification can be done easily.

Part 3

1) What is JVM? JVM enables to convert the source code into the code which can be executed in the system. This makes the java independent of the platform

2) Name four container classes? * Dialog * FileDialog * Panel * Frame

3) What is JAR file? JAR stands for java archive, it is used to compress a class of file.

4) What is typecasting? Typecasting converts entity of one type to entity of another type. It is very important while developing applications. Casting is of two types:- 1. downcasting 2. Upcasting

5) What is serialization and deserialization?



It is process of representing the state of an object in byte stream. Process of restoring the object is done be deserialization.

6) What is vector class? Vector class provides the capability to implement array of objects.

7) What is JVM and its use? The most important feature of Java is platform independent, this is supported by JVM. It converts the machine code into bytes. It is the heart of the java language and a structure programming language.

8) What are the difference between java and C++? Java adopts byte code whereas C++ doesn’t. C++ supports destructor whereas java doesn’t support. Multiple inheritance possible in C++ but not in java.

9) Difference between swing and AWT? AWT is works faster then swing since AWT is heavy weight components.AWT consist of thin layer of code, swing is larger and of higher functionality.

10) If a variable is declared as private, where may the variable be accessed? When the variable is declared private, it can be accessed only inside the class in which it is defined.

11) What is final? A final class cannot be sub classed neither extended. The variables cannot change the value.

12) What is static in java? Static methods are implicitly final, their methods are not attached to an object rather it is attached to a class.

13) Is null a keyword? NULL is not a keyword.

14) What is garbage collection? When an object is no longer used, java implicitly recalls the memory of the object. Since java doesn’t support destructor it makes use of garbage collector in the place of destructor.

15) What is the resourceBundle class?




It is used to store the local specific resources inorder to tailor the appearance.

16) What is tagged interface? Tagged interface is similar to the serializable interface, it instruct the complier to perform some activity.

17) What is overriding? When any class use the same name, type and arguments as that of the methods in the super class then the class can override the super class method.

18) What is referent? Referent variable are constant variable it cannot be modified to refer to any other object then the one with it was initialized.

19) What is the method to implement thread? Thread can be implemented by run() method

20) What is the difference between primitive scheduling and time slicing? In case of primitive scheduling the task with highest priority is performed until it enters the dead state. In case of time slicing it performs the task for sometime and then enter the ready state.

21) What are different types of access modifiers? public: accessible from anywhere. private: can be accessed only inside the class. protected: accessed by classes and subclasses of the same package. default modifier : accessed by classes contain the same package

22) What is the difference between subclass and superclass? Subclass doesn’t inherit anything from other classes whereas superclass inherit from other class.

23) What is a package? Package is a collection interface and class which provides a very high level of protection and space management.

24) What is the difference between Integer and int?- Integer defined in java. lang package which is a class, whereas int is a primitive data type defined in the Java



language itself.

25) What is synchronization? It is mechanism that allows only one thread to process the thread at a time. This is mainly to prevent deadlock.

Date : 8/9/2005Personal Interview ******************Some Tips**************

1. Something about uIt should about your family,childhood,schooling,B.E.,Future

2. Tell u'r Strength & Weakness

3. U should clearly explain u'r projects if they asked.

4. Area of interest

5. Have u attended any interviews before? If yes, then why haven't you get selected?

6. If u are not selected in my company then how do u feel?

7. Why are u choose this field?

8. What is u'r future plan?

9. If they tell "ask some questions regarding the company" u should ask questions

about the company

10. see the website of the particular company before attend the interview

11. why should we select u?

Here is some tips that will help u to prepare for hr interviews.Discuss it with

friends,"sorry" in case of any mistakes in this.

12. Prepare in advance --at least 2 days before ,so that u would be more fluent and

confident in interview.

13. When the interviewer asks "Tell about u r self"

start with"WITH PLEASURE SIR" -it is just to say "Thank u 4 giving me an

oppourtunity to tell about my self"




14. .Start with a difference

---------usually students start with "My name is......,My father's name is.....

Don't do the same ,Start some thing different like

"People call me as ....."

"My parents named me as ......."

"................is my name"

15. 4.Parents and family

After telling u r name ,tell u r parents name only.

A better approach would be "I'M PROUD TO BE THE SON OF MR.......AND

MRS......"

16. 5.Don't organize as conventional essay

------u can swap the facts just to give the impression that u r spontaneous and had

not prepared for this!!!!

For example,

After ur and ur parents details. u need not tell about u r school edu,

but u can start to tell about strengths.Later u can tell about u r school edu( this is

just to give an illusion that ur spontaneous)

17. 6.Prepare a speech for atleast 10 min.

--------------some times they expect even more...

18. 7.Tell atleast 5 strengths and justify

Don't use single line statements like

"I'm a confident person"

"I'm a hard worker"

Rather justify it.

For example if r a hardworker u can tell like this...

"sir ,i firmly belive in the power of hardworking.According to me the formula for

success is hardwork only.In the past if i had succeded in any thing it is only

because of my hardworking only....Because of my hard working





only........................

Because of my hard working only......................

Because of my hard working only I had cleared the aptitude test conducted by u

and in front of u.

List ur acheivements and tell hardwork as the key for it.....

Simillarly,What ever u say justify it.Tell hoew u implemented it.How it helped u.What u

acheived from it.How it will be usefull for the company.

Some of the strengths are.........

1. Hard working

2. Positive attitude

3. optimistic

4. Ability to learn from mistakes

5. Passion to learn new things

6. Helping tendency

7. time conciousness

8. Good memory

9. Extrovert person

10. Team worker

11. Leadership quality ........

Don't forget to justify,no single line sentences!!!!!

Give practical examples.....

Don't tell the weakness unless they ask

Don't tell more than one weakness.




If u tell any weakness ,Don't forget to tell how u rectified it or how u r working to

overcome it.

Don't be toooo honest in telling u r weakness.

ISRO Model Interview

Hope you all have started the planning for the DRDO test. This is a golden opportunity

to clear the test. Why? You have all the resources and books in your hand. Any way

many of you have asked how to apply for ISRO? Organizations like ISRO, VSSC etc

don’t conduct tests as DRDO do. They give ad in newspaper. They short list based on

the percentage and call for interview. Or they directly go to the premier institutes and

recruit directly from there.

I am giving a pattern of questions asked for an ECE guy in ISRO-SAC interview. Once

again I have to stress that if ur basics are strong you will get thru the interview. Now

from very long time I am telling learn the basics. What are the basics?

Here are examples:

1. In radar we may know how a CW radar works and what are its applications.

That’s not enough! You should know why the CW can be used in those applications

and what types of radar can be used in those applications other than CW radar.

2. In digital we know how to reduce a Boolean expression using K-map. But do you

know difference between looping 1s and 0s in K-map? Do you know there is a

limitation in Kmap? Do you know any other method to reduce the expressions? Is there

any limitation for that?

3. In mechanical we have heard a lot about 100cc or 150 cc bikes. What actually cc





here means? Is there any relationship with that with performance if so how and why?

Is there any 100% efficient Carnot cycle? Why?

4. In electrical we have heard a lot about transmission loss why it is caused? Can we

prevent it ?

5. In Computer you know methods of sorting? Which is the most efficient and why?

6. In Physics do you know what is the cause of hall effect?

Now have a first hand experience of an ISRO interview.

SAC (Ahmedabad) panel comprised of 6 members, very senior scientists. They asked

about B.E project, subject questions were picked up from the B.E project. Like if your

project is on Commn, they asked questions from Commn.

At NIT, Trichy ISRO dropped in for campus recruitment, panel members were from

ISRO Trivandrum and ISRO Bangalore with some 20 years of experience in ISRO.

3 people on the whole were in the panel. 1 was an expert in microwaves another person

in DSP, Digital Commn, VLSI, third person was chairman, I believe

They first made the usual formalities like doc verification and the usual questions like

Did u appear for GATE? How did u come 2 NIT, Trichy for PG (GATE / NON

GATE)?? What was your rank in the entrance test conducted by NITT to get in for

PG?

Then they asked abt my M.E project. Here at NITT, we have phase-1 project and

phase-2 project at 3rd and 4th semester course.

So i told that I am working with IP over WDM networks. They asked me from WDM

technology, to compare microwave and fiber optics, guided and unguided commn

differences? WDM components, about IPv6.

2nd member asked me from microwaves. Some questions raised by him







- Eqvt ckt of transmission line and explain all the primary and secondary constants?

- losses associated with transmission line

-antenna gain, isotropic antenna?, antenna applns at different freq

-microwave sources - klystron, magnetron etc.

3rd member asked me from digital commn

- Sampling theorem, aliasing effects, digital modulation (compare BPSK and BFSK),

what is FFSK?, line coding (compare Manchester and NRZ scheme), turbo codes??,

trellis coded modulation??, advantage of cyclic codes

some questions from spread spectrum also - like how anti jamming is achieved??

Altogether only basic fundas here also. Confidence is the key and it's better to have a

firm grasp on the subjects related to project.

Since the panel members were old people, questions from microwaves, antennas, trans

lines are sure to come forth.

In fact questions from microwave engineering, antennas and transmission lines were

asked for all people.

Test Paper :15 Paper Type : Technical - Java Test Date : 3 August 2009 Test Location : cochin Posted By : joice3I INFOTECH PAPER ON 16th SEPTEMBER 2007 Hi friends, This is Bipin Kadiri (SVMIT Bharuch 2007 passout ), I am going to share my experience with you about the interview of 3i-infotech. I wrote the written test on the 16th of september 2007. The written test is quite simple.You have to just practise the standard 2 books of R.S.Agarwal (quant aptitude & logical reasoning) once thats it. There were will be three sections of 50 questions each: 1.Logical Reasoning 2.Quantitative aptitude 3.English The test will be of 90 minutes duration.So fast calculation is important. A neagative marking of 0.25 marks for every wrong answer is there.so please be careful in that matter.. One more imp thing the questions both aptitude as well as GD & interview are ALL REPEATED So compulsorily go through the kind of questions mentioned here Section 1: English usageIn this there was a paragrap, nearly 400 words, about regularization of banking acts. On basis of this para there was q's . These are as follows---> 10 direct q's relataed to para





--> 3 Synoyms(Contemporay, Resilence etc.)--> 3 Antonyms--> 9 q's were based on fill in d blanksOn an aveage all d synonyms n antonyms were very easy and day to day conversational use. These synonyms and antonyms were given in bold in d para. While solving this type para plz keep in mind that one time reading with better comprehension is nt only helpful, bt u have o use regression. ( this is very tough I suggest u to do this later ) Remaining 15 q's were based on finding out grammatical error(u can see in any cat/ mat preparartion book). Some questions were of the type Jumbled sentences ( u construct a meaningful paragraph) On these some were diifficult. I suggest you not to attempt the questions based on the para first ( do only synonyms and antonyms ) and do the remaining ques first coz para is too tough and u will end up wasting ur time .In this section i did 35 q's. Section 2 : Reasoning--> Do a lot of questions from VENN DIAGRAMS RS Agarwal ( there will be atleast 5 qs of this type ) for eg : All shirts are clothes all clothes are garments some garments are blue and so on ......--> caselet based sitting arrangement--> q's based on Blood Relation(if A+B stands for A is father of B , A-B stands for Ais bro of B......... then what is A-B*c so on )--> q's based on critical resoning(like all banana's are mango, some mangoes are chilli then conclude...)--> q's based on series. In this you have to find out odd one in he series.( very imp all from RS Agarwal ) -> Some on coding decodingg--> Some were slightly different. These were like -- 5 different nos were given and said that 1 is added to the first digit of all numbers and 1 is subtracted from the middle digit. then Find out the second largest n so on.--> Some were Data Sufficiency--> Some questions were like 7@8 #6=50 ( very important )So what is 9@7#3 == ?? (ie 7*8=56- 6=50) so ( 9*7=63 -3 =60 ) I did around 17 questions in this section Section 3 : ArithmeticIn this topic on which Q's were based, is as -1. Probab -- 5 q's, in this q like--- there are different balls in a bag as3-green, 5-blue, 7-red. 6-black then find out the probab of getting 2 red balls, gtting at least 1 gren ball while picking up 3 balls n so on.2. Series Completion- 5 q (Entirely from RS Agarwal)3. Simplification-10-12 q, as (1) if 12.48 / ? / 56.4 = 12.3 then find ? and so on (Only calculation based but very easy ----------- must attempt)4. Compound Interest -1q (Direct Formula)5. Trains speed-1q as, A train crosses a platform of length double of its length, in 30 sec. Find speed of train.(Ans- can not determined)





6. Data Interpretation- 15 q, 2tables and 1 pie chart, vey easy just calculation basis.(but very lengthy) 7. Do the ques of linear equations , profit & loss and ratio and proprtion also.All depends on UR CALCULATION SPEED.So start mental calculation from today it will help u in this and other papers as well.All d Best..I did around 20 questions in this section Total around 65-70 questions were sufficient to put me n my friends thru The results were out on 12th of October.. Then we were called for GD and interview on 27th of October.First, i would like to tell you about the GD.My topic was Role of press is it invading our privacy ???there were other topics like "Cricket is a national obsession that is a detriment to other sports". "Politics can a person be corruption free in politics" "should celebrities participate in commercials". SPORTS tooo much importance to cricket diversity in India is it hampering unity leaders are born or made ???I was selected in GD also..GD is also okay..You have to be confident and atleast speak..but never keep mum.. Make three valid points atleast..Do not stick on only one point throughout the discussion..that also matters.. Whether u speak for the topic or against that is immaterial. .if points are good,think that you have cleared your GD. In a batch,out of 12, (4-5) of were selected... Coming to interview,mine was just HR but to computer & IT guys there were a few tech questionsThere will be a sir and a madam They asked me: descirbe urself ( dont say my name is ... and I got xy percent instead say I would like to introduce myself as a hardworking induvidual etc ) do u have a valid passport ?y do you want to wrok in software side ? r u willing to sign bond ?what r ur hobbies ?what was ur take in the GD ? a little bit regarding my academic project..what is sdlc?the steps involved in the same ur strengths and weaknesses justification for the same ...why are u leaving ur existing company?Family background ?where u see 5 years from now ?Do u wish to relocate? (ans should be yes definitely i love travelling ) where do u find urself after 3 years from now?what was ur role in the previous company?are u ready to work in any kind of profile?what is IT according to you? Then they asked me if i have any questions..I just asked what will be my role in the company if i get selected.. Thats it..The intvw is simple.You have to be confident.Thats it..

Write a program for the problem: the array of inetegers indicating the marks of the students is given, U have to calculate the percentile of the students aaccording to this rule: the percentile of a student is the %of no of student having marks less then him. For eg: suppose Student Marks A 12 B 60 C 80 D 71 E 30 F 45 percentile of C = 5/5 *100 = 100 (out of 5 students 5 are having marks less then him) percentile of B = 3/5*100 = 60% (out of 5, 3 have markses less then him) percentile of A = 0/5*100 = 0%.

2) The code was given for a problem and u have to midentitfy the logical error in it. That was simple. The code was to merge the Danagrams of 2 words. The danagram of a word is the letters of word arranfed in sequential order. eg danagram of abhinav is aabhinv. merging of danamagram is to merge the danagrams of 2 or more words such that the highest no of occurance are coming for each alphabet.eg merging of aabhinv and abbhhixz is aabbhhinvxz.

3) total no of 4 in betweeen 4 and 444

4)one distance travel on square edges speed was given average speeed was to calculate...

some more questions were on time and distance....like the onbe of bird and motorcylist....etc..

5)paper was very time consuming and tough to solve .... no negetive marking was there.....

I have taken the written test 16 march 2005 and pattern is CORE JAVA : 20 JSP, SERVLETS : 10 EJB : 10 STRUTS : 5 OOAD : 5 DB : 5 Total :55 cut off 60% ie. 33 they said.

do strong enough in core java they r so tricky reaming r ok DB also simple like use of TO_CHAR() function..... I cleared the written and they called me Thursday 24,and told me I am having tech on Sunday 27. I cleared tech also. Again in interview they concentrated on core java. They have taken around 45 mts in which they asked around 35 mts on corejava. Right from oops, inheritance, polymorphism, exceptions, threading. They asked some theoretical questions as well as they will gave some sample code and ask whether they compile or not,r un or not...like. they asked overloading, overriding which includes exceptions. So guys&gals be strong in CORE JAVA. later they asked few questions on servlets/jsp. (Paper Submitted By: Ramesh)

1. Graphics:Painters algorithm is used for...........

2. Graphics:Why is 'Lighting' operations done on World Coordinates?

3. Graphics:One more question

4. Some question on C External Variables.









5. How can you call a function written in FORTRAN from a C program ?

6. Normal question on pointer addition

7. Another question on pointer adition

8. A question on 64 bit OS's and Virtual Memory it will be having

9. Another question on 64 bit OS10. A structure was given and it contained normal data as well as some bit-

wise data.You had to find the total size taken up by the structure

11. A big code with lots of pointers. There was a struct which contained 2

arrays. Then an array of that structure was declared. The code used these

structures and you had to find the values of a variable 'j' at various points inside

the code

12. A code which had some declarations of some data items. There were a

couple of normal data items(char,int..) and some pointers as well and a malloc

call. You have to find the total memory taken up in the stack(Hint:Pointers and all

are allocated in heap, not in stack, so dont count them).Also in most of these

questions, they were specifying that the OS was 32 bit

13. A question on nesting of pointers. There was this pointer to a function

which returned an array of char pointers.....You had to give the exact definition of

the function

14. Value of 2 particular variables in C(MAXINT and some other constant)

15. What do you need to do to open more than 10 files simultaneously in

Microsoft Operating System? -change stdio.h/change

CONFIG.SYS/compiler dependent

Test Paper :229 Paper Type : Technical - Java Test Date : 1 April 2005 Posted By : Sibly SATYAM - JAVA TEST ON APRIL 2005------------------------------------------------------------------- Interview Question at Satyam for JAVA platform holding 3 yrs of Exp-------------------------------------------------------------------

1) What is diffrence between StateFul and Stateless Session Bean?

A Stateful Session Bean is a bean that is designed to service business processesthat span multiple method requests or transactions. Stateful Session beansretain state on behalf of an individual client. Stateless Session Beans do notmaintain state.

EJB containers pools stateless session beans and reuses them to service manyclients. Stateful session beans can be passivated and reused for other clients.But this involves I/O bottlenecks. Because a stateful session bean caches clientconversation in memory, a bean failure may result in loosing the entire clientconversation. Therefore, while writing a stateful session bean the bean developer has to keep the bean failure and client conversation loss in mind.

In case of stateless session beans, client specific data has to be pushed to thebean for each method invocation which will result in increase in the networktraffic. This can be avoided in a number of ways like persisting the clientspecific data in database or in JNDI. But this also results in I/O performancebottlenecks.



If the business process spans multiple invocations thereby requiring aconversation then stateful session bean will be the ideal choice. On the otherhand, if business process lasts only for a single method call, stateless sessionbean model suits.

Stateful session beans remembers the previous request and responses. Butstateless beans do not. stateful does not have pooling concept, whereas thestateless bean instances are pooled

-------------------------------------------------------------------

2) What is difference between BeanMangedPersistance and ContainerMangedPersistance?

CMP: Tx behaviour in beans are defined in transaction attributes of the methods

BMP: Programmers has to write a code that implements Tx behaviour to the bean class.

Tuned CMP entity beans offer better performance than BMP entity beans. Movingtowards the CMP based approach provides database independence since it does notcontain any database storage APIs within it. Since the container performsdatabase operations on behalf of the CMP entity bean, they are harder to debug.BMP beans offers more control and flexibility that CMP beans.

Diff 1) In BMP you will take care of all the connection and you write the SQLcode inside the bean whereas in CMP the container will take care of itDiff 2) The BMP is not portable across all DB's.whereas the CMP is

-------------------------------------------------------------------

(3)Draw and explain MVC architecture?

MVC Architecture is Module- View-Controller Architecture. Controller is the onewhich controls the flow of application / services the requests from the View.Module is the other layer which performs the exact operations. Each layer shouldbe loosely coupled as much as possible.

-------------------------------------------------------------------

(4)Difference between forward(request,response) and SendRedirect(url) in Servlet?



With Forward, request & response would be passed to the destination URL whichshould be relative (means that the destination URL shud be within a servletcontext). Also, after executing forward method, the control will return back tothe same method from where the forward method was called. All the opposite tothe above points apply to sendRedirect.(OR)The forward will redirect in the application server itself. It does not cometo the client. whereas Response.sendredirect() will come to the client and goback ...ie. URL appending will happen.

-------------------------------------------------------------------

(5)What is Synchornize?

Synchronize is a technique by which a particular block is made accessible onlyby a single instance at any time. (OR) When two or more objects try to access aresource, the method of letting in one object to access a resource is called sync

-------------------------------------------------------------------

(6)How to prevent Dead Lock?

Using synchronization mechanism.

For Deadlock avoidance use Simplest algorithm where each process tells max numberof resources it will ever need. As process runs, it requests resources but neverexceeds max number of resources. System schedules processes and allocates resouresin a way that ensures that no deadlock results.

-------------------------------------------------------------------

7)Explain different way of using thread? :

The thread could be implemented by using runnable interface or by inheritingfrom the Thread class. The former is more advantageous, 'cause when you aregoing for multiple inheritance..the only interface can help

-------------------------------------------------------------------

(8)what are pass by reference and passby value?



Pass By Reference means the passing the address itself rather than passing thevalue. Passby Value means passing a copy of the value to be passed.

-------------------------------------------------------------------

(9)How Servlet Maintain Session and EJB Maintain Session?

Servlets maintain session in ServleContext and EJB's in EJBContext.

-------------------------------------------------------------------

(10)Explain DOM and SAX Parser?

DOM parser is one which makes the entire XML passed as a tree Structure andwill have it in memory. Any modification can be done to the XML.

SAX parser is one which triggers predefined events when the parserencounters the tags in XML. Event-driven parser. Entire XML will not be storedin memory. Bit faster than DOM. NO modifications can be done to the XML.

-------------------------------------------------------------------

(11)What is HashMap and Map?

Map is Interface and Hashmap is class that implements that and its notserialized HashMap is non serialized and Hashtable is serialized

-------------------------------------------------------------------

(12)Difference between HashMap and HashTable?

The HashMap class is roughly equivalent to Hashtable, except that it isunsynchronized and permits nulls. (HashMap allows null values as key and valuewhereas Hashtable doesnt allow). HashMap does not guarantee that the order ofthe map will remain constant over time.

-------------------------------------------------------------------

(12a) Difference between Vector and ArrayList?

Vector is serialized whereas arraylist is not



-------------------------------------------------------------------

(13)Difference between Swing and Awt?

AWT are heavy-weight componenets. Swings are light-weight components. Henceswing works faster than AWT.

-------------------------------------------------------------------

14) Explain types of Enterprise Beans?

Session beans -> Associated with a client and keeps states for a clientEntity Beans -> Represents some entity in persistent storage such as a database

-------------------------------------------------------------------

15) What is enterprise bean?

Server side reusable java component

Offers services that are hard to implement by the programmer

Sun: Enterprise Bean architecture is a component architecture for thedeployment and development of component-based distributed business applications.Applications written using enterprise java beans are scalable, transactional andmulti-user secure. These applications may be written once and then deployed onany server plattform that supports enterprise java beans specification.

Enterprise beans are executed by the J2EE server.

First version 1.0 contained session beans, entity beans were not included.Entity beans were added to version 1.1 which came out during year 1999.Current release is EJB version 1.2

-------------------------------------------------------------------

16)Services of EJB?

Database management :–Database connection pooling–DataSource, offered by the J2EE server. Needed to access connection pool of the server.–Database access is configured to the J2EE server -> easy to change database / database driver





Transaction management :

–Distributed transactions–J2EE server offers transaction monitor which can be accessed by the client.

Security management :

–Authetication–Authorization–encryption

Enterprise java beans can be distributed /replicated into separate machines

Distribution/replication offers–Load balancing, load can be divided into separate servers.–Failover, if one server fails, others can keep on processing normally.–Performance, one server is not so heavy loaded. Also, for example Weblogic has thread pools for improving performance in one server.

-------------------------------------------------------------------

17)When to choose EJB?

Server will be heavy loaded :–Distribution of servers helps to achieve better performance.

Server should have replica for the case of failure of one server:–Replication is invisible to the programmer

Distributed transactions are needed "–J2EE server offers transaction monitor that takes care of transaction management.–Distributed transactions are invisible to the programmer

Other services vs. money :

Weblogic J2EE server ~ 80 000 mk and Jbuilder X Professional Edition ~ 5 000mk

-------------------------------------------------------------------

18)Why not to use free J2EE servers?




–no tecnical support–harder to use (no graphical user interface ...)–no integration to development tools (for example, Jbuilder)–Bugs? Other problems during project?

-------------------------------------------------------------------

19) Alternative:TuxedoTuxedo is a middleware that offers scalability services and transaction monitors.C or C++ based.Can be used with Java client by classes in JOLT package offered by BEA.

Faster that J2EE server?Harder to program?Harder to debug?

Implementation is platform dependent.

-------------------------------------------------------------------

20) J2EE server offers

DataSource:–Object that can be used to achieve database connection from the connection pool.–Can be accessed by the interface DataSource

Transaction monitor:–Can be accessed by the interface UserTransaction.

Java Naming and the Directory Service :

-------------------------------------------------------------------

21)Java Naming and the Directory Service

Naming service is needed to locate beans home interfaces or other objects (DataSource, UserTransaction):–For example, jndi name of the DataSource

Directory service is needed to store and retrieve properties by their name:–jndi name: java:comp/env/propertyName

-------------------------------------------------------------------




22)XML – deployment descriptor

ejb-jar.xml + server-specific xml- file Which is then Packed in a jar – filetogether with bean classes.Beans are packaged into EJB JAR file , Manifest file is used to list EJB’s andjar file holding Deployment descriptor.

-------------------------------------------------------------------

23) Session Bean

Developer programs three classes:–Home interface, contains methods for creating (and locating for entity beans) bean instances.–Remote interface, contains business methods the bean offers.–Bean class, contains the business logic of the enterprise bean.

-------------------------------------------------------------------

24)Entity Beans

Represents one row in the database:–Easy way to access database–business logic concept to manipulate data.

Container managed persistence vs. bean managed persistence:

Programmer creates three or four classes:–Home interface for locating beans–Remote interface that contains business methods for clients.–Bean class that implements bean’s behaviour.–Primary key class – that represents primary key in the database. Used to locate beans.Primary key class is not needed if primary key is a single field that could

-------------------------------------------------------------------

25) When to use which bean?

Entity beans are effective when application wants to access one row at a time.If many rows needs to be fetched, using session beans can be better alternativeava class (for example, Integer).



Entity beans are efficient when working with one row at a timeCause a lot of network trafic.

Session Beans are efficient when client wants to access database directry.–fetching/updating multiple rows from the database

-------------------------------------------------------------------

26) Explain J2EE Arch?

Normally, thin-client multitiered applications are hard to write because theyinvolve many lines of intricate code to handle transaction and state management,multithreading, resource pooling, and other complex low-level details.The component-based and platform-independent J2EE architecture makes J2EEapplications easy to write because business logic is organized into reusablecomponents and the J2EE server provides underlying services in the form of acontainer for every component type. Because you do not have to develop theseservices yourself, you are free to concentrate on solving the business problemat hand.

Containers and Services :Component are installed in their containers during deployment and are theinterface between a component and the low-level platform-specific functionalitythat supports the component. Before a web, enterprise bean, or applicationclient component can be executed, it must be assembled into a J2EE applicationand deployed into its container.The assembly process involves specifying container settings for each componentin the J2EE application and for the J2EE application itself. Container settingscustomize the underlying support provided by the J2EE Server, which includeservices such as security, transaction management, Java Naming and DirectoryInterfaceTM (JNDI) lookups, and remote connectivity.

Container Types :The deployment process installs J2EE application components in the followingtypes of J2EE containers. The J2EE components and container addressed in thistutorial are shown in Figure 5.An Enterprise JavaBeans (EJB) container manages the execution of allenterprise beans for one J2EE application. Enterprise beans and theircontainer run on the J2EE server.A web container manages the execution of all JSP page and servlet componentsfor one J2EE application. Web components and their container run on the J2EEserver.





An application client container manages the execution of all applicationclient components for one J2EE application. Application clients and theircontainer run on the client machine.An applet container is the web browser and Java Plug-in combination running onthe client machine.

Discretion abt written Selection Process

Written Test:

Prepare from previous papers. It’s of the same pattern.Prepare wordlist from Barrons.

There was no psychometric test.We had only 1 and a half hr to complete the paper. For

quants, we had to write the answers and were not of multiple choices. Logical questions

were bit tough.Main problem is the time shortage to complete it fully.

Interview

There were around 8 - 10 panels for tech intrw held at TCS, Karapakkam,

Chennai.Environment was excellent.

People from TCS were very soft and had a cheerful face.

In my panel, two persons of age around 35 – 40 yrs interviewed me.Tech intrw was held

for around 55 min. Slightly drilling but easy.After clearing tech, I attended HR where one

young man interviewed me.It went for half an hour exactly.Most of them were only

personal questn and some tech Qs.On my time slot, 5 ppl attended in that same panel and

only 2 cud get thro.

For another friend, the tech held for just 10min.They asked 2 gen. Qs like where he is

from (Ambattur) and how he reached that office.Then 2 tech Qs 1) Shannons theory ?

come to software?

Why not hardware?

What guarentee u give that u won’t shift to hardware after 2 yrs saying u don’t

like S/w?

Another person asked what u studied in Engineering economics & mgmt?

R u interested in this subj?

I frankly said it’s a bit boring subj. ‘coz there is nothing to learn and this is the

subj where we write stories.They smiled.

If we put u in proj dealing with mgmt,…..difft from what u’ve studied in BE, r u

ready to do that?

U said it’s a boring subj. & now ready to switch over to that ?

First of all, working at TCS itself is a great pleasure and it would be my duty to

develop interest in that subject and shine well in that area.

Finally they asked ‘any Qs 2 us’?

Yes sir!

On what electronics related proj r u working currently?

Then I smiled and said ‘then there is a chance for me to get into electronics based

s/w projects’.

Posted By : Jai Quantitative Questions

1 If g (0)=g (1)=1 And g (n)= g (n-1) + g (n -2) find g (6);

Ans: g(6) = 13

Sol:

G(0) = 1

G(1) = 1

G(2) = G(1) + g(0) = 2

G(3) = g(2) + g(1) = 3

G(4) = g(3) + g(2) = 5

G(5) = g(4) + g(3) = 8

G(6) = g(5) +g (4) = 13

2 A plane moves from 9?N40?E to 9?N40?W. If the plane starts at 10 am and takes 8

hours to reach the

destination, find the local arrival time?

Ans:



The time is calculated on the basis of longitude. (Based on sunrise)Sun rises earlier

in calcutta than in Mumbai. The 40 degrees east and 40 degress west are calculated form 0 degrees. The plane

has travelled westwards by

40+ 40 = 80 Degrees. (WEST) For each degree there is a difference of 4 Minutes

The difference in timings is

320 Minutes behind.As per the starting point time 10.00 AM the flight should have

reached at 6.00 PM.

Reducing 320 Minutes from it we get 12.40 PM local time at the destination

3 Given $ means Tripling and % means change of sign then,find the value of $%$6-%$%6 ANS: -724 The size of a program is N. And the memory occupied by the program is given by M = square root of 100N. If the size of the program is increased by 1% then how much memory now occupied ?

6. A traveler walks a certain distance. Had he gone half a kilometer an hour faster \, he

would have walked it in

4/5 of the time, and had he gone half a Kilometer an hour slower, he would have

walked 2 ½ hr longer. What





is the distance?

a) 10 Km b) 15 Km c) 20 Km d) Data Insufficient Ans: b)

Sol: distance == speed x time

st == (s + .5) x .8t -------------------(1)

st==.8st +.4t

. 2st==.4t

s== 2KM

st== (s - .5)x(t+150) ------------------(2)

Sustituting you will get the distance as 15 KMs

7. A ship leaves on a long voyage. When it is 18 miles from the shore, a seaplane,

whose speed is 10 times that of

the ship is sent to deliver mail. How far from the shore does the seaplane catch upo

with the ship?

a) 24 miles b) 25 miles c) 22miles d) 20 miles Ans:

(d-18)==st

d=st

d=(d-18)

180== 9d

8. In a circular race track of length 100 m, three persons A, B and C start together. A

and B start in the same

direction at speeds of 10 m/s and 8 m/s respectively. While C runs in the opposite at

15 m/s. When will all the

three meet for the first time on the after the start?

a) After 4 s b) After 50 s c) After 100 s d) After 200 s Ans : c)

Sol: Since the track is a circular track A and B will meet every 50 seconds. ie

100/(10-8) Since it is a multiple

of 50 they will be meeting at the starting point every 50 Seconds. if you multiply 15

x 50 you will get 750 and

after the second 50 it will be 1500.All of them will meet at the starting point after

100s




9 Amal bought 5 pens, 7 pencils and 4 erasers. Rajan bought 6 pens, 8 erasers and 14

pencils for an amount

which was half more than what Amal had paid. What % of the total amount paid by

Amal was paid for pens?

a) 37.5% b) 62.5% c) 50% d) None of these Ans : b) 62.5%

Sol: You can observe from the question that for additiion of 1 pen 7 pencils and 4

erasers rajan pays 50 %

more.It implies that the cost of 4 pens is 50% of the total amount paid by Amal.

Therefore cost of 5 pens will

be 62.5% of the total cost.

10. A non stop bus to Amritsar overtakes an auto also moving towards Amritsar at 10

am. The bus reaches

Amritsar at 12.30 pm and starts on the return journey after 1 hr. On the way back it

meets the auto at 2 pm. At

what time the auto will reach Amritsar?

a) 2.30pm b) 3.00pm c) 3.15pm d) 3.30pm Ans : b) 3.00pm

Sol: let the distance between the meeting point of Auto at 10.00 Am and Amritsar

be d The bus takes 2.5

Hours(150 minutes) to reach amritsar from that point. The bus commences its return

journey at 1.30 PM and

meets auto at 2.00 PM. The bus has thus travelled 30 Minutes. The bus would have

covered 30/150 d

The auto has covered (1-1/5)d during the period. is 4/5th of the distance has been

covered in 4 hours (2.00

PM -10.00 AM) The remaining 1/5th distance will be covered in 1 hour. The auto

will reach Amritsar at 3.00

PM

11. The cost of one pencil, two pens and four erasers is Rs.22 while the cost of five

pencils, four pens and two

erasers is Rs.32.How much will three pencils, three pens and three erasers cost?

Sol:





x + 2y + 4z == 22

5x + 4y + 2z == 32

Solving we get 3x + 2 y == 14 and y + 3z == 13, Adding both we get 3x + 3y +3z

== 27 Ans : 27

12. The lowest temperature in the night in a city A is 1/3 more than 1/2 the highest

during the day. Sum of the

lowest temperature and the highest temperature is 100 degrees. Then what is the

low temp?

Sol:

(1/2 + 1/3x1/2)t + t == 100

solving we get t == 60 ie the highest temperature is 60 and the lowest is 40.

Ans : 40 degrees

13. Javagal, who decided to go to weekened trip should not exceed 8 hours driving in a

day. The average speed of

forward journey is 40 miles/hr.Due to traffic on sundays, the return journey's

average speed is 30 m/h. How far

he can select a picnic spot?

a) 120 miles b) between 120 and 140 miles c) 160 miles Ans: 120 miles

Sol:

The answer given by you appears to be wrong. The question is not clear regarding

the day on which the

onward trip is carried out. If it is on a Saturday the maximum distance that can be

travelled is 8 x 30 == 240

miles.However if both the onward and return trips are carried out on Sunday the

answer is Between 120 and

140 Miles. The time taken for both the trips is 8 hours.

3 x 40 =0

4 x30 =0.

One more hour can be utilised for travelling and more than 120 miles can be

covered.




14 The total expense of a boarding house are partly fixed and partly variable with the

number of boarders. The

charge is Rs.70 per head when there are 25 boarders and Rs.60 when there are 50

boarders. Find the charge

per head when there are 100 boarders.

a) 65 b) 55 c) 50 d) 45

Ans : b)

Sol: The total cost for 25 boarders is 25 x 70 = 50 ,The total cost for 50 boarders is

50 x 60 == 3000,

The difference is 1250 for 25 boarders.,The variable cost per boarder is Rs 50

For additional 50 boarders the increase in total cost is 50 x 50 == 2500,Therefore

total cost for 100 boarders

is 3000 + 2500 == 5500. The charge per head works out to Rs 55.

15. A car has run 10000 miles using 5 tyres interchangably,To have a equal wornout by

all tyres. how many miles

each tyre should have run. Ans: 4000 miles/tyre

Sol:

According to me the answer given is wrong. A car runs on four wheels. The

aggregate distance covered by the

four wheels is 10000 x 4 == 40000 miles. Since 5 tyres are used interchangably the

distance covered by each

tyre will be 40000/5 == 8000 miles.

16. In 80 coins one coin is counterfiet what is minimum number of weighings to find

out counterfiet coin

Ans: 4 weighings.

27 27 26

17. There are two trees in a lawn. One grows at a rate 3/5 of the other in 4 years. If the

total growth of trees is 8 ft.



What is the height of the smaller tree after 2 years Ans: 1 1/2 feet (Less than 2

feet).

Sol: After four years the combined height of the two trees is 8 ft.the ratio at that

point is 3/5 : 1

therefore 3/5x + x == 8, solving x == 5 The height of the smaller tree after 4 years

is 3 ft

At the end of two years it would have been 3/2 ft.

18 A building with height D shadow upto G. What is the height of a neighbouring

building with a shadow of C

CALSOFT PAPER - AUG 2005I have attended my written test in calsoft. In the call letter they said that its a 2 hr test. but the questions are really tough. I got "BBB" Q paper. In that 16 from DBMS,5 from Data structures,9 from Networking , 20 programming questions in c&c++ and 50 Aptitude ques.More over 2 programs we should write,one is pseudo code and other one is C prog, Seperate Sheets will be given. These are not exact questions. these are just i remember. I think it will be useful..In DBMS most of the questions from SQL syntaxData structure questions are simple like1. what is the sorting algorithm with less time.2.Which one is efficient? Bubble search or Sequential Search.other three are about queues..Networking questions are about the basic concepts like what is the network layer protocol?what is the length of IP address nowadays?what device used to covert analog to digital and viceversa?more questions about routers.. the programming questions are really brain hungry but if u have practice and wellverse in commands . it will be easy job..More questions are about error detection..( program errors)The aptitude question are really tough..Time was not sufficient..have practice in Numbers, Ages, Frations and basic mathematical formulae.. The programs i got are1.Pseudo code for inserting a node into a list.2.C prog for converting numbers into long words.That is if 10201 then the out put should be like" ten thousand two hundred and one"without using any sprintf or any special commands. only printf is allowed

Test Paper :4 Paper Type : Technical - Java Test Date : 15 April 2010 Test Location : PUNE Posted By : AbhishekHi Amodocs Written pattern is as below :

b. logical reasoningif + = / and - = * and / = + and * = - then1) 2+4/5-7*8 equal to

c. learning ability : one passage is given we have to read the passage and find the answers.

2. Technical - Java, unix and sql

java: 1. some question on thread and trace the output of the program

sql:some question on index and view and query related questions, some on permission and constraints question most of the theoretical questions.

unix;

1. command for comparing two files2. cat file1 file2 >> file3 find output.3. which command is used to create a sub processes4. ls -l ! grep unix > temp.txt what is output.5. how to delete 100 lines in vi editor using single command6 which key is used to reach to the end of line7. if temp.txt contains 100 lines how to print 11th line
