Okay, that makes sense. I generally try to do that anyway, as far as return
the interface.

What I don't understand is how you could get around getters and setters for
something like an int. The only production coding I've done in Java is an
order entry process.

What I did was create a class to represent a customer, a class to represent
an address, and an interface for an order. I then created a CustomerOrder
class that implemented the Order interface. But, if the order quantity is an
integer field, is that the instance where a getter and setter is okay? I
assume some of this opinion, but I'm curious to see how others handle this.
