23种设计模式

Here are three short phrases to help remember the 23 design patterns, ordered by category:

Creational Patterns: "Abstract Building Factories Produce Stuff" (5 words)

Structural Patterns: "Adapted Bridges Connect Different Facades, Flyweight Proxy" (7 words)

Behavioral Patterns: "Caffeine Is Intoxicating; It Makes Others Stop, Stay, Struggle, Try, Visit." (11 words) 咖啡因是有毒的；它让其他人停下来、停留、挣扎、尝试、造访。

Note that these phrases are just one way to remember the patterns, and you may find it helpful to come up with your own mnemonic device or use another method to memorize them.

大家都说设计模式可根据目的划分为：

1、创建型（creational）：主要用于处理对象的创建，实例化对象

2、结构型（structural）：处理类或对象间的组合

3、行为型（behavioral）：描述类或对象怎样进行交互和职责分配

   但是让我疑问的是，为什么大家都约定俗成的把n个设计模式分门别类到这三个类别中去呢？分类的具体依据呢？创建型就真的用来创建对象？结构型就组合对象吗？它是怎么创建怎么组合的呢？

   带着这些问题，笔者再度整理了一下思绪，提出几个特征明显的给您娓娓道来~至于针对每一类模式的进一步总结，敬请期待接下来的博文。
