    ok i am confused...

    what about arrays?

    if:

    int i[] = {1};

    and i pass it to a method and the method changes it, the actual array is changed. so after the initial change in a method, if that method exits and another method calls the same array, what is stored in the array is what the previous method changed it to, not the original. I was always told that that was passing by reference, help please.

    thanks

    Did you read the tutorials you were given? Basically, the thing that's being passed by value is a reference to the array. The tutorials explain it quite well, so I won't go into it further here.
