Question

Give the output of the following Java statements: (i)"TRANSPARENT".toLowerCase()
(ii) "TRANSPARENT".compareTo("TRANSITION")

Answer 1

Answer:

String a = "Java is a programming language\ndeveloped by\t\'James Gosling\'";

System.out.println(a);

Java is a programming language developed by ‘James Gosling’

d) Differentiate between break and System.exit(0).

The break keyword is used to terminate a loop or a switch statement.

System.exit(0) is used to terminate a program.

e) Write a statement in Java for:

Math.sqrt((Math.pow(a + b), 3) / Math.abs(a - b))

f) What is the value of m after evaluating the following expression:

m -= 9 % ++n + ++n / 2; when int m = 10, n = 6;

m = m – (9 % ++n + ++n / 2)

= 10 – (9 % 7 + 8 / 2)

= 10 – (2 + 4)

= 10 – 6

= 4.

g) Predict the output of the following:

(i) Math.pow(25, 0.5) + Math.ceil(4.2)

= 5.0 + 5.0

= 10.0

(ii) Math.round(14.7) + Math.floor(7.9)

15.0 + 7.0

= 22.0

Answer 2
