Why doesn't changing the pre to the post increment at the iteration part of a for loop make a difference?

Question

Why does this

 int x = 2;
    for (int y =2; y>0;y--){
        System.out.println(x + \" \"+ y + \" \");
        x++;
    }

prints the s

Answer 1

Because nothing in your examples is using the value returned from the pre- or post-increments. Try wrapping a System.out.println() around the ++x and x++ to see the difference.
