Behavioral Patterns

Behavioral patterns are those patterns which are specifically concerned with communication (interaction) between the objects. The interactions between the objects should be such that they are talking to each other and still are loosely coupled. The loose coupling is the key to n-tier architectures. In this, the implementations and the client should be loosely coupled in order to avoid hard-coding and dependencies.
The behavioral patterns are:

1. Chain of Resposibility Pattern
2. Command Pattern
3. Interpreter Pattern
4. Iterator Pattern
5. Mediator Pattern
6. Momento Pattern
7. Observer Pattern
8. State Pattern
9. Strategy Pattern
10. Template Pattern
11. Visitor Pattern
