《Head First设计模式》(中文版)共有14章，每章都介绍了几个设计模式，完整地涵盖了四人组版本全部23个设计模式。前言先介绍这本书的用法；第1章到第11章陆续介绍的设计模式为Strategy、Observer、Decorator、Abstract Factory、Factory Method、Singleton，Command、Adapter、Facade、TemplateMethod、Iterator、Composite、State、Proxy。最后三章比较特别。第12章介绍如何将两个以上的设计模式结合起来成为新的设计模式(例如著名的MVC模式)，作者称其为复合设计模式(这是作者自创的名称，并非四人组的标准名词)，第13章介绍如何进一步学习设计模式，如何发觉新的设计模式等主题，至于第14章则很快地浏览尚未介绍的设计模式，包括Bridge、Builder、Chain of Responsibility、Flyweight、Interpreter、Mediator、Memento、Prototype，Visitor。第1章还介绍了四个○○基本概念(抽象、封装、继承、多态)，而第1章到第9章也陆续介绍了九个○○原则(Principle)。千万不要轻视这些○○原则，因为每个设计模式背后都包含了几个○○原则的概念。很多时候，在设计时有两难的情况，这时候我们必须回归到○○原则，以方便判断取舍。可以这么说：○○原则是我们的目标，而设计模式是我们的做法。
