Creational design patterns are used to design the instantiation process of objects. The creational pattern uses the inheritance to vary the object creation.

1. Builder
2. Prototype
3. Factory
4. Abstract Factory
5. Singleton

Structural patterns are concerned with how classes and objects are composed to form larger structures. Structural class patterns use inheritance to compose interfaces or implementations.

1. Adapter
2. Composite
3. Proxy
4. Bridge
5. Decorator
6. Flyweight
7. Facade

Behavioral patterns are concerned with algorithms and the assignment of responsibilities between objects. Behavioral patterns describe not just patterns of objects or classes but also the patterns of communication between them. These patterns characterize complex control flow that’s difficult to follow at run-time.

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