public static void main(String[] args) {
Integer x = 0;
Integer y = 0;
for(Short z = 0; z < 5; z++)

If a for isn't followed by braces, it loops the statement that follows the for.
In this case "If" is the looped statement.

I think the output is x=8 y=2
the syntax

it's ok
the for cycle iterates 5 times
1st: x=1 , y=1
2nd: x=2 , y=2
3rd: x=4 , y=2
4th: x=6 , y=2
5th: x=8 , y=2

The answer of this question is 8 2.

As said in the earlier post - If a for isn't followed by braces, it loops the statement that follows the for.
In this case "If" is the looped statement.

Here we are looping 5 times and each time values of X and Y are:
x y
0 - 1 1
1 - 2 2
2 - 4 2 (As the first expr is evaluated as TRUE, second expr won't executed)
3 - 6 2 (As the first expr is evaluated as TRUE, second expr won't executed)
4 - 8 2 (As the first expr is evaluated as TRUE, second expr won't executed)
