Things I know…

• This is a required class in several degree programs, including all Engineering degrees.

• Some students take this class who don’t want to be here.• Most of you have used computers since you were children.• Some of you have never written a computer program.• Some of you have written many computer programs.• Many of you are anxious about your ability to succeed in this

class.• Many of you are in your first or second year of college and

still adapting to the challenges it presents.• Some of you are here for the second time…welcome back!

3

Things you should know…• This class requires a lot of work – it will keep you busy!

– Once you get behind it’s increasingly difficult to catch up– You are in lecture two and half hours, and in lab two hours a week– Programming assignments (labs) may take from 1-8+ hours to

complete– Quiz preparation requires additional time– Exam preparation requires additional time

• I’m hopeful that every one of you will earn an A.

4

Also…

• Don’t hesitate to email me or come by my office. – I can’t often reply right away, but I will always reply.– It is fun to help students who are working hard and trying– Don’t bother calling me if your car broke down or your alarm didn’t go off.

There’s nothing either of us can do to fix unfortunate occurrences.

• If you own a laptop, you may bring it to class and lab– We will practice writing code in some classes, and this offers you the

opportunity to better follow, practice and learn.– BUT…Do not use it for email, Facebook, or other class assignments.

• If you are using your cellphone in class, I will probably notice– And I’ll probably assume that this class is not a priority for you– Please exercise self discipline and ignore it until after class

Success Factors:Please do:•Come to class on time.•Find a classmate to get notes from in case you miss due to illness.•Participate in class and lectures.•Be 100% engaged and present for 50 minutes three times a week.•Utilize office hours, lab sessions, and the CSE help desk.•Feel free to study together for quizzes and exams. (not lab assignments)

Please don’t:•Skip class…ever.•Collaborate on lab assignments.•Ask for a makeup quiz, exam, or lab extension (unless you have an official university absence)•Ask for extra credit…however, you may drop one lab and one quiz grade.

Motivation for Learning• Software (i.e., the instructions you write) controls hardware

hardware (i.e., computers). • Computer use is increasing in almost every field of

endeavor. • Computing costs are dropping dramatically. • More than a billion general-purpose computers are in use

worldwide.• Computer Software is pervasive – it affects most aspects of

our personal and professional lives.

Programming• You’ll learn to write instructions commanding computers to

perform tasks. • Over the years, many programmers learned structured

programming. • You’ll learn structured programming and object-oriented

programming—the key programming methodology used by programmers today.

• You’ll create and work with many software objects. – Their internal structure is often built using structured-programming

techniques. • The logic of manipulating objects is occasionally expressed

with structured programming.

13

Java• Java is one of today’s most popular languages for

developing software. • Java has become the language of choice for implementing

Internet-based applications and software for devices that communicate over a network.

• There are now billions of Java-enabled mobile phones and handheld devices.

• Java is the preferred language for meeting many organizations’ enterprise wide programming needs.

Java programming is not the primary goal.However, it is an essential tool to achieve the goal.

Java We will use Java Standard Edition (Java SE) Version 6 (or higher) Java Enterprise Edition (Java EE)

geared toward developing large-scale, distributed networking applications and web-based applications.

Java Micro Edition (Java ME) geared toward developing applications for small, memory-constrained

devices, such as cell phones, pagers and PDAs.
