Different tools, same problems.  The different tools reflect an evolution of what Object Oriented best summed up by: Composition over inheritance. The rethink, the new concepts and how to use them are explained here. Abstract Classes Interfaces:  Duck Typing with Safety Multiple Interfaces… Continue reading Interfaces, Delegation & Composition vs Multiple Inheritance & Duck Typing
