JAVA设计模式
定义:提供创建目标的接口.为何使用?工厂模式是我们最常用的模式了,著名的Jive论坛,就很多使用了工厂模式,工厂模式在Java程序系统可以说是随处可见。为何工厂模式是如此常用?由于工厂模式就相当于创建实例目标的new,我们经常要基于类Class生成实例目标,如Aa=newA()工厂模式也是用来创建实例目标的,所以今后new时就要多个心眼,是不是可以思考有效工厂模式,尽管这样做,也很多做一些工作,但会给你系统带来更大的可扩展性和尽量少的修改量。我们以类Sample为例,如果我们要创建Sample的实例目标:JAVA设计模式.chm
(Definition: Provide an interface to create a target. Why use it? The factory pattern is the most commonly used pattern. The famous Jive forum uses the factory pattern a lot. The factory pattern can be seen everywhere in the Java program system. Why is the factory pattern so commonly used? Since the factory pattern is equivalent to creating an instance target new, we often need to generate instance targets based on the class Class, such as Aa=newA() The factory pattern is also used to create instance targets, so in the future, when new If you need multiple minds, you can think about the effective factory pattern. Although doing so will do a lot of work, it will bring greater scalability to your system and minimize the amount of modification. Let's take the class Sample as an example, if we want to create an instance target of Sample:
