Do you know Singleton, Factory, Decorator, Adapter, Fa軋de, Strategy, State, MVC? As you might have guessed, they are all patterns from the GoF book. But if you are like me, you might know couple of them and a lot of times you are confused. If that’s the case, you should read this article on java.net about those patterns. The authors prepare you for a holiday conversation on design patterns. They will help you look like a true guru. Fun and interesting article. I really liked it.
