Java doesn't have pointers!  Just mudying the waters, or was it serious?  If so sorry.

Think of it as chucking water over someone, as opposed to passing them a cup of water.  Thats
pretty similar.

or, um, having someone talk to you, rather than pass you a piece of paper. hmmm.

J,

Subject:  RE: Java Trivia


Obviously, the first is passed by value, but the second?  We know p will
reference the same object it referenced before the method invocation - the
memory location it points to is the same.  Because p will always point to
the same memory location, is it not also passed by value?

What's the difference between

int i = 3;
someMethod( i);

and

Point p = new Point( 3, 3);
someOtherMethod( p);

?
