Design Patterns are various code patterns developers use when working in an Object-Oriented programming language such as Java.

All of the design patterns in this repo are implemented using Java, however could be implemented/adapted in an OO language such as C++ or Ruby.

Below are is a list of all the design patterns covered in this Wiki and repo:

• Creational
  • Abstract Factory
  • Builder
  • Factory Method
  • Prototype
  • Singleton
• Structural
  • Adapter
  • Bridge
  • Composite
  • Decorator
  • Facade
  • Flyweight
  • Proxy
• Behavioral
  • Chain of Responsibility
  • Command
  • Interpreter
  • Iterator
  • Mediator
  • Memento
  • Observer
  • State
  • Template Method
  • Visitor

The code examples are all based off of the Design Patterns: Elements of Reusable Object-Oriented Software book. The book itself uses C++ and Smalltalk in its own examples, and it can be a bit tricky to see exactly how the same patterns can be applied in Java.
