What is a Design Pattern?

Design Patterns are reusable solutions to commonly occurring problem in software design.

Types of Design Patterns

Design Patterns are grouped under three categories - Creational, Structural and Behavioral.

Creational Design Patterns

Creational Design Patterns focus on the creation of objects. This helps us in reusing exisiting code.

Following are the list of Creational Design Patterns.

• Singleton
• Factory
• Abstract Factory
• Builder
• Constructor
• Prototype

Structural Design Patterns

Structural Design Patterns focuses on assembly of objects into larger composition and also keeping structural efficiency and flexibility.

Following are the list of Structural Design Patterns.

• Adapter
• Bridge
• Flyweight
• Facade
• Decorator
• Proxy
• Composite

Behavioral Design Patterns

Behavioral Design Patterns focuses on the algorithms and assignments of responsibilities between objects and communication between them.

Following are the list of Behavioral Design Patterns.

• Strategy
• Observer
• Command
• Iterator
• Mediator
• Visitor
• State
