[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：

2.1  Man.java
package chouxiang;
/*
 * 抽象产品类Man
 */
public interface Man {

    public void makeM();
    
}
2.2  WhiteMan.java
package chouxiang;

public class WhiteMan implements Man {
    public void makeM() {
        System.out.println("我是白种男人！");
    }
    
}
2.3  YelloeMan.java
package chouxiang;

public class YellowMan implements Man {
    public void makeM() {
        System.out.println("我是黄种男人！");
    }
    
}
2.4  BlackMan.java
package chouxiang;

public class BlackMan implements Man {
    @Override
    public void makeM() {
        System.out.println("我是黑种男人！");
    }
    
}
2.5  Woman.java
package chouxiang;
/*
 * 抽象产品类Woman
 */
public interface Woman {

    public void makeW();
}
2.6  WhiteWoman.java
package chouxiang;

public class WhiteWoman implements Woman {
    @Override
    public void makeW() {
        System.out.println("我是白种女人！");
    }
    
}
2.7  YellowWoman.java
package chouxiang;

public class YellowWoman implements Woman {
    public void makeW() {
        System.out.println("我是黄种女人！");
    }
    
}
2.8  BlackWoman.java
package chouxiang;

public class BlackWoman implements Woman {
    @Override
    public void makeW() {
        System.out.println("我是黑种女人！");
    }
    
}
2.9  Color.java
package chouxiang;
/*
 * 抽象工厂类 （肤色）
 */
public interface Color {
    
 public Man produceMan();
 public Woman produceWoman();
    
}
2.10  White.java
package chouxiang;
/*
 * 具体工厂类 白色肤色
 */
public class White implements Color{
    @Override
    public Man produceMan() {
        return new WhiteMan();
    }
    @Override
    public Woman produceWoman() {
        return new WhiteWoman();
    }
}
2.11  Yellow.java
package chouxiang;
/*
 * 具体工厂类 黄色肤色
 */
public class Yellow implements Color{
    @Override
    public Man produceMan() {
        return new YellowMan();
    }
    @Override
    public Woman produceWoman() {
        return new YellowWoman();
    }
}
2.12  Black.java
package chouxiang;
/*
 * 具体工厂类 黑色肤色
 */
public class Black implements Color{
    @Override
    public Man produceMan() {
        return new BlackMan();
    }
    @Override
    public Woman produceWoman() {
        return new BlackWoman();
    }
}
2.13  XMLUtil.java
package chouxiang;

/*
 * 读取XML文件并根据存储在XML文件中的类名获取对应的对象
 */

                 System.out.println("类名:  "+ cName); //输出类名
                 
                 //通过类名生成实例对象返回
                 Class<?> c = Class.forName("chouxiang."+cName);
                 Object obj = c.newInstance();
                 return obj;
         } catch (Exception e) {

             return null;
         }
         
     }

2.14  Client.java
package chouxiang;
/*
 * 客户端测试类
 */
public class Client {
    public static void main(String[] args) {
        try 
        {
