Behavioral design patterns are design patterns that identify common communication patterns between objects and realize these patterns. By doing so, these patterns increase flexibility in carrying out this communication.

Behavioral patterns

1. Chain of Responsibility --A way of passing a request between a chain of objects
2. Command --Encapsulate a command request as an object
3. Interpreter --A way to include language elements in a program
4. Iterator --Sequentially access the elements of a collection
5. Mediator --Defines simplified communication between classes
6. Memento --Capture and restore an object's internal state
7. Observer --Alter an object's behavior when its state changes
8. State --Alter an object's behavior when its state changes
9. Strategy --Encapsulates an algorithm inside a class
10. Template Method --Defer the exact steps of an algorithm to a subclass
11. Visitor --Defines a new operation to a class without change
