系统对产品对象的创建需求由一个工程的等级结构满足,其中有两个具体工程角色,即UnixFactory和WindowsFactory。UnixFactory对象负责创建Unix产品族中的产品,而WindowsFactory对象负责创建Windows产品族中的产品。这就是抽象工厂模式的应用,抽象工厂模式的解决方案如下图: 显然,一个系统只能够在某一个操作系
publicstaticvoidmain(String[] args) { KingdomFactory factory =newOrcKingdomFactory(); Army orcArmy = factory.createArmy(); King orcKing = factory.createKing(); Castle orcCastle = factory.createCastle(); System.out.println(orcArmy.getDescription()); System.out.println(orcKing.getDescription())...
Learn in Java 1. Overview The Abstract Factory is a software design pattern whose goal is to provide a single interface to create families of objects with the same theme but without exposing the concrete implementation. This pattern provides another layer of abstraction over the factory pattern. ...
