ISRO | ISRO CS 2013 | Question 63

What is the output of the following Java program?

Class Test
{
 public static void main (String [] args)
 {
 int x = 0;
 int y = 0;
 for (int z = 0; z < 5; z++)
 {
 if((++x > 2) || (++y > 2))
 {
 x++;
 }
 }
 System.out.println( x + " " + y);
 }
}

(A) 8 2
(B) 8 5
(C) 8 3
(D) 5 3


Answer: (A)

Explanation: By applying short circuit technique,

z = 0: x = 1, y = 1, if condition false
z = 1: x = 2, y = 2, if condition false
z = 2: x = 3, if condition true and due
to short circuiting ++y is not evaluated,
x++ // x = 4
z = 3: x = 5, again if condition is true,
x++ // x = 6
z = 4: x = 7, condition true, x++ // x = 8

So, option (A) is correct.
