[Java] What does a semicolon do directly after a "for" loop?
Author Summary

Post Body

In my text book it simply states that a semicolon after a "for" loop causes to loop to only execute once, and does not provide much in the way of an example.

    int x = 0;
    for (int j = 1; j <= 79; j  );{

        x  ;
        }
     System.out.println(x);

I placed this in and ran it and the output was x = 1, which I expected. Now I am given this code...

    int p = 6;
    int m = 20, j;
    for (j = 1; j < p; j  );{

        m = m   j * j;
    }
    System.out.println(m);

and when I run it, I get 56 back. I want to know how 56 was taken out of this, because if it was only run once, would it not return 21?

Thanks for any help on treating my understanding of this.
