抽象工厂模式

[实验任务一]：人与肤色
使用抽象工厂模式，完成下述产品等级结构：

1. 画出对应的类图；
   
2. 提交源代码；
   Black.java

package PeopleAndSkinColor;

public class Black implements Color{
    @Override
    public Man produceMan() {
        return new BlackMan();
    }
    @Override
    public Woman produceWoman() {
        return new BlackWoman();
    }
}

BlackMan.java

package PeopleAndSkinColor;

public class BlackMan implements Man {
    @Override
    public void makeM() {
        System.out.println("我是黑种男人！");
    }

}

BlackWoman.java

package PeopleAndSkinColor;

public class BlackWoman implements Woman {
    @Override
    public void makeW() {
        System.out.println("我是黑种女人！");
    }

}

Client.java
