Wow, there's a lot of stuff here to digest... We're getting into inheritance next week, so some of this should make more sense then.
I'm getting the hang of this interface stuff now, though. I thought he was saying that it was meant for writing a method once and then sharing it amongst different classes, but now I see what it is. It makes a lot more sense now. It's just a way of tying a bunch of classes together and making sure they all use the same methods... well, in addition to their own methods.
Also, he had mentioned that it can be used as a way to divide work amongst different teams. I kind of get that part already. Team collaboration was one of the first things I thought of when I saw him setting up the lab. Then I got all messed up with the way he was explaining the "sharing classes" aspect of it.
