工厂方法模式Java 的相关内容

23种设计模式，工厂方法模式的概念优缺点以及JAVA代码举例

工厂方法模式是设计模式中的一种创建型模式，它主要解决的问题是对象创建的问题。它定义了一个创建对象的接口，但让实现这个接口的类来决定实例化哪一个类。工厂方法让类的实例化推迟到子类中进行。工厂方法模式的概念在工厂方法模式中，我们不再使用单个类来创建所有类型的对象，而是创建一个接口或者抽象类来指定生成...

设计模式之工厂方法模式（Java实现）

一、认识工厂模式工厂模式定义：定义一个创建产品对象的工厂接口，将产品对象的实际创建工作推迟到具体子工厂中，实现了创建者与调用者的分离！工厂模式分类：简单工厂模式、工厂方法模式、抽象工厂模式。简单工厂模式：将被创建的对象称为"产品"，把创建产品的对象称为"工厂"...
