Simple While Looping Question

[J.TiMo]

Hello,

It's a very simple looping question but I want to figure it out why the result is this.

int y = 6;
while(y-- > 1){
System.out.println(y);
}

Output:
5
4
3
2
1

Why 1 is shown on output?

Thanks.

because after you have written "2" to the console y==2.

Then the while loop checks if the condition is true -> 2>1 is true so it decrements y by 1, and continue to the loop. And now y==1.

Remember that y--, first uses the variable y in the expression, then it decrements it.

If you had used --y instead you would not have 1 written out, because you would have done the decrement before you check the condition.

Cheers

Thank you so much! I totally understand why now.
