Unit 4: Operators in Java

What is the value of x1 if x=5?

x1 = ++x – x++ + – –x

Evaluate the value of n if value of p = 5, q = 19

int n = (q – p) > (p – q) ? (q – p) : (p – q);

Find the output of the following program segment, when:

int val=1600, sum, n = 550;

sum = n + val > 1750 ? 400 : 200;

System.out.println(sum);

What is the value of y, when the following statements are executed?

int a = 63, b = 36;

int y = (a < b) ? a : b;

If a = 5, b = 9 calculate the value of a += a++ – ++b + a.

What is the value of x, when the following statements are executed?

int a = 63, b = 36;

boolean x = (a > b) ? true : false;

What will be the output for the following program segment?

int a = 0, b = 30, c = 40;

a = – –b + c++ + b;

System.out.println(“a = ”+a);

Evaluate the following expression, if the values of the variables are a = 2, b = 3 and c = 9.

a * (++b) % c

What is the value of y after evaluating the expression given below?

y += ++y + y–– + ––y; when int y=8

If m = 5 and n = 2 output the value of m after execution in the following expression:

n = m + m / n;
