简单工厂模式-女娲造人

1.工程文件

接口类Human的使用可以更方便的扩展功能，如添加更多人种。

2.Human.java
通过输出不同的语言来识别人种。

package simple_factory_model;public interface Human {public void talk();}

3.WhiteHuman.java

package simple_factory_model;public class WhiteHuman implements Human{public void talk() {System.out.println("Hello!");}
}

4.YellowHuman.java

package simple_factory_model;public class YellowHuman implements Human{public void talk() {System.out.println("你好！");}}

5.BlackHuman.java

package simple_factory_model;public class BlackHuman implements Human{public void talk() {System.out.println("Olá.");}}

6.HumanFactory.java

package simple_factory_model;public class HumanFactory {public static Human createHuman(String s) {Human human=null;if(s.equals(new String("whiteHuman")))human=new WhiteHuman();if(s.equals(new String("yellowHuman")))human=new YellowHuman();if(s.equals(new String("blackHuman")))human=new BlackHuman();return human;}}

7.NvWa.java

package simple_factory_model;public class NvWa {public static void main(String[] args) {// TODO 自动生成的方法存根Human human=HumanFactory.createHuman("yellowHuman");human.talk();}}
