Creational patterns: Provide a structure to create objects easily, provide certain flexibility on its creation, and reuse existent code. Behavioral Design Patterns:Used in communications between entities and make it easier and more flexible for these entities to communicate. We'll also discuss another category of design pattern: J2EE design patterns. You will learn what they are and how they can be applied.
