Java challenge

Question

Hello there!
Someone could tell me how 52 the output of this code?

int x = 0;
int y = 0;
for (int z = 1; z < 5; z++) {
if (( ++x > 2) && (++y > 1)) {
x++;
}
}
System.out.println(x +""+ y);

I see how x increasing with x++, but I can't understand how y works.
I am kind of new at Sololearn. Any chance that are the challenges have wrong solution?

Answer 1

CEORF

a > 1 && b > 1

b will only execute when a is true

So in case of your problem y will not change until ++x is false

If there was or ( || ) then y will execute when ++x is false but in case of ++x true y will not change.

Answer 2

For z=1

x=1 but x is not greater than 2 which renders the whole expression as false , i. e. It doesn't proceeds to check for 2nd statement(++y>1) .

For z=2
x=2 , x>2 is false.

For z=3
x=3, x>2 is true .
y=1, x>2 and y>1 is false.

For z=4
x=4, x>2 is true .
y=2, x>2 and y>1 is true and x=5

Final value for x=5 and y=2.

Answer 3

So y stay 0 while the statement before it (x>2) doesn't get true.

Thank you!
