Overview

A collection of design patterns in Java. My aim is to implement all of them (with documentation) as a learning resource/ reference point for myself and others.

Creational	Structural	Behavioral
Abstract factory	Adapter	Chain of responsibility
Builder	Bridge	Command
Factory	Composite	Iterator
Prototype	Decorator	Mediator
Singleton	Facade	Memento
Object pool	Flyweight	Observer
	Proxy	State
		Strategy
		Template method
		Visitor

Building

To build, just do a Maven build. Also included is findbugs, jacoco, PMD and checkstyle.

Running

Tests are written that run and explain each pattern - so you can try them individually.

Pull Requests

Pull requests are very much welcome! Please note, every pull request should have:

• A matching JUnit Test (with good coverage)
• Run and fixed any checkstyle errors (run mvn checkstyle:checkstyle) [if you don't build will fail]
• PMD (run mvn pmd:pmd) and Findbugs should also be run and best effort to resolve issues
