Java实现软件设计模式---抽象工厂模式(性别产品等级结构肤色产品族）

一、题目要求

二、画出对应的类图

三、文件目录结构

 

 四、具体实现代码

Black.java

package com.a004;

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

    @Override
    public Woman produceWoman() {
        return new BlackWoman();
    }
}

BlackMan.java

package com.a004;

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

BlackWoman.java

package com.a004;

public class BlackWoman implements Woman {

    @Override
    public void play() {
        System.out.println("我是黑种女人！");
    }
}

Color.java

package com.a004;

public interface Color {
    public Man produceMan();
    public Woman produceWoman();
}

Yellow.java

package com.a004;

public class Yellow implements Color{
    @Override
    public Man produceMan() {
        return new YellowMan();
    }

    @Override
    public Woman produceWoman() {
        return new YellowWoman();
    }
}

White.java

package com.a004;

public class White implements Color {
    @Override
    public Man produceMan() {
        return new WhiteMan();
    }

    @Override
    public Woman produceWoman() {
        return new WhiteWoman();
    }
}

Man.java

package com.a004;

public interface Man {
    public void play();
}

WhiteMan.java

package com.a004;

public class WhiteMan implements Man {
    @Override
    public void play() {
        System.out.println("我是白种男人！");
    }
}

YellowMan.java

package com.a004;

public class YellowMan implements Man{
    @Override
    public void play() {
        System.out.println("我是黄种男人！");
    }
}

Woman.java

package com.a004;

public interface Woman {

    public void play() ;
}

WhiteWoman.java

package com.a004;

public class WhiteWoman implements Woman {
    @Override
    public void play() {
        System.out.println("我是白种女人！");
    }
}

YellowWoman.java

package com.a004;

public class YellowWoman implements Woman {
    @Override
    public void play() {
        System.out.println("我是黄种女人！");
    }
}

五、测试代码以及配置代码

XMLUtil.java

package com.a004;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.xml.sax.SAXException;
import java.io.File;
public class XMLUtil {
    public static Object getBean() {
        try {
                //创建DOM文档对象
                DocumentBuilderFactory dFactory = DocumentBuilderFactory.newInstance();
                DocumentBuilder builder = dFactory.newDocumentBuilder();
                Document doc;
                doc = builder.parse(new File("config.xml"));
                //获取包含类名的文本节点
                NodeList nl = doc.getElementsByTagName("className");
                Node classNode = nl.item(0).getFirstChild();
                String cName = classNode.getNodeValue();
                System.out.println("类名:  "+ cName); //输出类名
                //通过类名生成实例对象返回

            Object obj = null;
            try {
                Class c =Class.forName("com.a004."+cName);
                obj = c.newInstance();
            } catch (ClassNotFoundException e) {
                System.out.println("ClassNotFoundException");
                e.printStackTrace();
            } catch (InstantiationException e) {
                System.out.println("InstantiationException");
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                System.out.println("IllegalAccessException");
                e.printStackTrace();
            }
            return obj;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

config.xml

<?xml version = "1.0"?>
<config>
    <className>Black</className>
</config>

Client.java

package com.a004;
public class Client {
    public static void main(String[] args) {
        Color color;
        Man man;
        Woman woman;
        color=(Color) XMLUtil.getBean();
//        color=new White();
        woman=color.produceWoman();
        woman.play();
        man=color.produceMan();
        man.play();
    }
}
