The best way to remember design patterns

There are three basic classifications of patterns: Creational, Structural, and Behavioral patterns.



Creational Patterns


  • 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 in which only a single instance can exist



Note: The best way to remember Creational Pattern is by remembering ABFPS (Abraham Became First President of States).

Structural Patterns


  • Adapter: Match interfaces of different classes

  • Bridge: Separates an object’s abstraction from its implementation

  • Composite: A tree structure of simple and composite objects

  • Decorator: Add responsibilities to objects dynamically

  • Façade: A single class that represents an entire subsystem

  • Flyweight: A fine-grained instance used for efficient sharing

  • Proxy: An object representing another object


Note: To remember Structural Pattern best is (ABCDFFP)

Behavioral Patterns


  • Mediator: Defines simplified communication between classes

  • Memento: Capture and restore an object's internal state

  • Interpreter: A way to include language elements in a program

  • Iterator: Sequentially access the elements of a collection

  • Chain of Resp: A way of passing a request between a chain of objects

  • Command: Encapsulate a command request as an object

  • State: Alter an object's behavior when its state changes

  • Strategy: Encapsulates an algorithm inside a class

  • Observer: A way of notifying change to a number of classes

  • Template Method: Defer the exact steps of an algorithm to a subclass

  • Visitor: Defines a new operation to a class without change


Note: Just remember Behavioral Pattern Music....... 2 MICS On TV (MMIICCSSOTV).
