object oriented programming: looking for good tutorials [closed]

Answer 1

Object-Oriented-Design-Heuristics is great and appropriate for your needs IMHO. Head First Design Patterns is wonderful also, with interesting examples of incorrect and correct practices for certain cases.

Answer 2

You might be able to find some good advice on programming techniques, but there's no wax-on-wax-off for coding skills. You learn by doing it. Mostly by doing it wrong a lot at first. I know it sucks, but it's the way it is.
