Its range is from -32768 to 32767.2. What is the range of data type byte in Java?a) -128 to 127b) -32768 to 32767c) -2147483648 to 2147483647d) None of the mentionedView AnswerAnswer:aExplanation:Byte occupies 8 bits in memory. Its range is from -128 to 127.3. Which of the following are legal lines of Java code?1. int w = (int)888.8;2. byte x = (byte)100L;3. long y = (byte)100;4. byte z = (byte)100L;a) 1 and 2b) 2 and 3c) 3 and 4d) All statements are correct.View AnswerAnswer: dExplanation:Statements (1), (2), (3), and (4) are correct. (1) is correct because when a floating-point number (a double in this case) is cast to an int, it simply loses the digits after the decimal.(2) and (4) are correct because a long can be cast into a byte. If the long is over 127, it loses its most significant (leftmost) bits.(3) actually works, even though a cast is not necessary, because a long can store a byte.4. An expression involving byte, int, and literal numbers is promoted to which of these?a) intb) longc) byted) floatView AnswerAnswer: aExplanation:An expression involving bytes, ints, shorts, literal numbers, the entire expression is promoted to int before any calculation is done.5. Which of these literals can be contained in a data type float variable?a) 1.7e-308b) 3.4e-038c) 1.7e+308d) 3.4e-050View AnswerAnswer: bExplanation:Range of data type float is 3.4e-038 to 3.4e+308.6. Which data type value is returned by all transcendental math functions?a) intb) floatc) doubled) longView AnswerAnswer:cExplanation:None.7. What is the output of this program?1. class average {2. public static void main(String args[])3. {4. double num[] = {5.5, 10.1, 11, 12.8, 56.9, 2.5};5. double result;6. result = 0;7. for (int i = 0; i < 6; ++i) 8. result = result + num[i];9. System.out.print(result/6);10. 11. } 12. }a) 16.34b) 16.566666644c) 16.46666666666667d) 16.46666666666666View AnswerAnswer:cExplanation:None.output:$ javac average.java$ java average16.466666666666678. What is the output of this program?1. class conversion {2. public static void main(String args[]) 3. { 4. double a = 295.04;5. int b = 300;6. byte c = (byte) a;7. byte d = (byte) b;8. System.out.println(c + " " + d);9. } 10. }a) 38 43b) 39 44c) 295 300d) 295.04 300View AnswerAnswer:bExplanation:Type casting a larger variable into a smaller variable results in modulo of larger variable by range of smaller variable. b contains 300 which is larger than bytes range i:e -128 to 127 hence d contains 300 modulo 256 i:e 44.output:$ javac conversion.java$ java conversion39 449. What is the output of this program?1. class increment {2. public static void main(String args[]) 3. { 4. int g = 3;5. System.out.print(++g * 8);6. } 7. }a) 25b) 24c) 32d) 33View AnswerAnswer:cExplanation:Operator ++ has more preference than *, thus g becomes 4 and when multiplied by 8 gives 32.output:$ javac increment.java$ java increment3210. What is the output of this program?1. class area {2. public static void main(String args[]) 3. { 4. double r, pi, a;5. r = 9.8;6. pi = 3.14;7. a = pi * r * r;8. System.out.println(a);9. } 10. }a) 301.5656b) 301c) 301.56d) 301.56560000View AnswerAnswer:aExplanation:None.output:$ javac area.java$ java area301.5656
