单例模式（Singleton Pattern）是一个比较简单的模式，其定义如下：Ensure a class has only one instance, and provide a global point of access to it.（确保某一个类只有一个实例，而且自行实例化并向整个系统提供这个实例。）单例模式的使用场景在一个系统中，要求一个类有且仅有一个对象，如果出现多个对象就会出现“不...

责任链模式定义如下：Avoid coupling the sender of a request to its receiver by giving more than one object a chance tohandle the request.Chain the receiving objects and pass the request along the chain until an ...

命令模式是一个高内聚的模式，其定义为：Encapsulate a request as an object,therebyletting you parameterize clients with different requests,queue or log requests,and support undoableoperations.（将一个请求封装成一个对象，从而让你使用不同的请求把客户端...

中介者模式的定义为：Define an object that encapsulates how a set of objectsinteract.Mediator promotes loose coupling by keeping objects from referring to each otherexplicitly,and it lets you vary their interact...

原型模式（Prototype Pattern）的简单程度仅次于单例模式和迭代器模式。正是由于简单，使用的场景才非常地多，其定义如下：Specify the kinds of objects to create using a prototypical instance,and create new objects bycopying this prototype.（用原型实例指定创建对象的种类，并...

建造者模式（Builder Pattern）也叫做生成器模式，其定义如下：Separate the construction of a complex object from its representation so that the sameconstruction process can create different representations.（将一个复杂对象的构建与它的表示分离，...

模板方法模式（Template Method Pattern）是如此简单。其定义如下：Define the skeleton of an algorithm in an operation,deferring some steps to subclasses.TemplateMethod lets subclasses redefine certain steps of an algorithm ...

抽象工厂模式（Abstract Factory Pattern）是一种比较常用的模式，其定义如下：Provide an interface for creating families of related or dependent objects without specifyingtheir concrete classes.（为创建一组相关或相互依赖的对象提供一个接口，而且无须指定它们的具体类...

工厂方法模式使用的频率非常高，在我们日常的开发中总能见到它的身影。其定义为：Define an interface for creating an object,but let subclasses decide which class toinstantiate.Factory Method lets a class defer instantiation to subclasses.（定义一个...
