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

Try this example:

int i = 6;
System.out.println(i++);
System.out.println(i);

i = 10;
System.out.println(++i);
System.out.println(i);

You should be able to work out what it does from this.
