Discussion Forum : Operators and Assignments - Finding the output (Q.No. 7)
7.
What will be the output of the 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);
}
}
Answer: Option
Explanation:
In the first two iterations x is incremented once and y is not because of the short circuit && operator. In the third and forth iterations x and y are each incremented, and in the fifth iteration x is doubly incremented and y is incremented.

output of int z=2; while(z<20) if((z++)%2==0) system.out.println(z);

x=1 >2 wrong
z++
z=1
x=2>2 wrong
z++
z=2
x=3>2 yes
&&
1>2? wrong
z=3
x=4
2>2 rong
z=4
x=5
3>2 yes.
x++ x=6.
So, o/p: 6 3.
z++
z=1
x=2>2 wrong
z++
z=2
x=3>2 yes
&&
1>2? wrong
z=3
x=4
2>2 rong
z=4
x=5
3>2 yes.
x++ x=6.
So, o/p: 6 3.

@Arnold.
Thank you for explaining the short circuit operator's operation in detail.

@All.
Check the first condition and till it is true it won't go to the second condition so when x becomes 3 and the condition satisfies (3>2) then only condition two comes into consideration like y=1 then x also increments by 4.
