Notice that based on the input parameter, different subclass is created and returned.getComputeris the factory method. Here is a simple test client program that uses above factory design pattern implementation. package com.journaldev.design.test; import com.journaldev.design.factory.ComputerFactory; im...
如下「进口水果」的代码,为 O'Reilly 的「C# 3.0 Design Patterns」这本书籍 [1] 第五章的 Factory Method 示例。乍看之下,我觉得它比较像 Simple Factory Pattern,因其仍将创建实例,和部分逻辑判断的工作,都集中在一个 工厂类 (Creator1 类) 去处理,导致日后要添加新功能 (多引进一个国家的水果),或要修...

Factory Pattern An important facet of system design is the manner in which objects are created. Although far more time is often spent considering the object model and instance interaction, if this simple design aspect is ignored it will adversely impact the entire system. Thus, it is not only...
