Java设计模式--抽象工厂(Abstract Factory) 概述定义:为创建一组相关或相互依赖的对象提供一个接口,而且无需指定它们的具体类。抽象工厂模式又称为Kit模式。工厂方法模式是用来创建一个产品的等级结构的,而抽象工厂模式是用来创建多个产品的等级结构;针对多个业务品种、业务分类 是一种对象创建型模式。 学习难度:★★★...
🚀一、简单工厂模式(Simple Factory Pattern) 简单工厂模式是创建型设计模式,又被称为静态工厂方法(Static Factory Method)模式,虽然它不包含在经典的23种GoF(Gang of Four)设计模式之中,但却是学习其他工厂模式的重要前提。 在简单工厂模式中,一个工厂对象负责根据输入的条件来创建不同种类的产品类的实例。这种模...
