大话设计模式

《大话设计模式【Java溢彩加强版】》延续了前作轻松调侃的风格，采用了师生对话的方式展开讨论，其中穿插了大量“接地气”的类比案例，帮助大家迅速“开窍”，作者精心将本书图表制作成彩色三维形式，阅读起来你会发现，不仅仅是养眼，对一些流程、概念的解说，用彩色三维图表更为精准，学习体验有了质变。

在上一版出版至今的长达15年里，本书一直是国内原创计算机类图书畅销榜霸榜产品。不过本书前作确实存在一些不足和缺憾，有很大提升空间。

 此次升级对书中的大量细节做了更新，增补或者替换了更加便于理解的解读和案例。

 对原书中工厂方法模式的内容进行了彻底重写。

 对部分章节，如装饰模式、观察者模式、抽象工厂模式、单例模式等内容做了较大改动。

 对很多模式的讲解内容和代码样例做了完善，比如同一个商场收银程序的不断迭代升级在策略模式、装饰模式、工厂方法模式、抽象工厂模...
