It's simple... for any software you run into ask yourself: How can it work? How does it work? How it should work? And the most important thing: Avoid involving yourself into code that is a mess before knowing how it should be written in the first place. Also, if you're into OOP, think about access modifiers as: private - if it's called from somewhere it has to be only in this class... (or im gonna slap someone!) protected - only this class and its child classes... public - does this really has to be part of an interface? Once you start thinking this way you know you're on the right track. ...and read a lot. :)
