设计模式Java实现——序言(0)

　　设计模式是很有经验的面向对象的程序员总结出的最佳实践，这个系列主要来自于翻译https://www.tutorialspoint.com/design_pattern/index.htm上的所有设计模式，通过简单的示例帮助人们理解各种设计模式的概念。

　　设计模式最早是由Gang of Four在Design Patterns - Elements of Reusable Object-Oriented Software提出并整理的，其中的每种模式都参考书中的内容，23种设计模式可以被分为3类：Creational, Structural and Behavioral，另外还讨论J2EE design patterns，以下是这个系列的所有的设计模式标题。
