Creational Patterns

  Abstract Factory

  Creates an instance of several families of classes

  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 Patterns

  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 Patterns

  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

  • I have scenario based question and I want a required help please tell me how many Patterns I required to solve my problem?

    We are creating an application for shape drawing. We have to support multiple shapes

    like circle, rectangle, square, polygon etc. These shapes may are related to each other

    like square is a type of rectangle where rectangle is also kind of polygon. We want to

    have an option of theme as well in our application. This theme option will allow us to

    draw shapes with some filled content like marble theme will allow us to create shapes

    filled with marbles where flower theme will allow us to create shape filled with flowers.

    By default user can create shapes with borders with no fill. In order to provide

    convenience to user we have an imaginary shape like Frame. The idea to introduce

    frame is to hold different shapes so user can move or apply effects in one go.

    Create classes / interfaces for given problem?
