These are also famous as gang of four design patterns
Creational Design Patterns : for the way objects are created
Abstract Factory- Creates an instance of several families of classes Builder- Separates object construction from its representation Factory Method- Creates an instance of several derived classes Prototype- A fully initialized instance to be copied or cloned Singleton- A class of which only a single instance can exist
Structural Design Pattern : for the way objects organsed in the datastructure
Adapter- Match interfaces of different classes Bridge- Separates an object’s interface from its implementation Composite- A tree structure of simple and composite objects Decorator- Add responsibilities to objects dynamically Facade- A single class that represents an entire subsystem Flyweight- A fine-grained instance used for efficient sharing Proxy- An object representing another object
Behavioral Design Patterns :for the way objects interact each other
Chain of Resp.- A way of passing a request between a chain of objects Command- Encapsulate a command request as an object Interpreter- A way to include language elements in a program Iterator- Sequentially access the elements of a collection Mediator - Defines simplified communication between classes Memento - Capture and restore an object's internal state Observer - A way of notifying change to a number of classes State - Alter an object's behavior when its state changes Strategy - Encapsulates an algorithm inside a class Template Method - Defer the exact steps of an algorithm to a subclass Visitor - Defines a new operation to a class without change v
