Switch / Case problem

Ok, how can anyone have a problem with this, right? Well, I figured out a way.
Anyway, I've got a pretty simple statement, but for some reason, the values keep going to default rather than one of the cases.
Here's the code. It's in a method of a class called ant. Direction is defined as an int in the begining of the class and called in the constructor.
Code:
switch (Direction) {
case 0: posY++;
case 1: posX++; posY++;
case 2: posX++;
case 3: posX++; posY--;
case 4: posY--;
case 5: posX--; posY--;
case 6: posX--;
case 7: posX--; posY++;
default: println("Error. " + Direction);
}

at least 50% of the time I get a return of "error..." but the direction listed is one with a specific case already assigned... anyone have any ideas of what might be the problem?

you need a "break" (don't we all?) after each case.
Code:
and so on. Otherwise execution will carry on into the
next case (which can sometimes be useful, but not often.)
