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

 1 package com.a004;
 2
 3 public class Black implements Color{
 4     @Override
 5     public Man produceMan() {
 6         return new BlackMan();
 7     }
 8
 9     @Override
10     public Woman produceWoman() {
11         return new BlackWoman();
12     }
13 }

BlackMan.java

1 package com.a004;
2
3 public class BlackMan implements Man{
4     @Override
5     public void play(){
6         System.out.println("我是黑种男人！");
7     }
8 }

BlackWoman.java

1 package com.a004;
2
3 public class BlackWoman implements Woman {
4
5     @Override
6     public void play() {
7         System.out.println("我是黑种女人！");
8     }
9 }

 5     public Man produceMan() {
 6         return new YellowMan();
 7     }
 8

11         return new YellowWoman();
12     }
13 }

White.java

 6         return new WhiteMan();
 7     }
 8
 9     @Override

1 package com.a004;
2
3 public interface Man {
4     public void play();
5 }

1 package com.a004;
2
3 public class WhiteMan implements Man {
4     @Override
5     public void play() {
6         System.out.println("我是白种男人！");
7     }
8 }

YellowMan.java

1 package com.a004;
2
3 public class YellowMan implements Man{
4     @Override
5     public void play() {
6         System.out.println("我是黄种男人！");
7     }
8 }

Woman.java

1 package com.a004;
2
3 public interface Woman {
4
5     public void play() ;
6 }

WhiteWoman.java

1 package com.a004;
2
3 public class WhiteWoman implements Woman {
4     @Override
5     public void play() {
6         System.out.println("我是白种女人！");
7     }
8 }

YellowWoman.java

1 package com.a004;
2
3 public class YellowWoman implements Woman {
4     @Override
5     public void play() {
6         System.out.println("我是黄种女人！");
7     }
8 }

五、测试代码以及配置代码

XMLUtil.java

 1 package com.a004;
 2 import javax.xml.parsers.*;
 3 import org.w3c.dom.*;
 4 import org.xml.sax.SAXException;
 5 import java.io.File;
 6 public class XMLUtil {
 7     public static Object getBean() {
 8         try {
 9                 //创建DOM文档对象
10                 DocumentBuilderFactory dFactory = DocumentBuilderFactory.newInstance();
11                 DocumentBuilder builder = dFactory.newDocumentBuilder();
12                 Document doc;
13                 doc = builder.parse(new File("config.xml"));
14                 //获取包含类名的文本节点
15                 NodeList nl = doc.getElementsByTagName("className");
16                 Node classNode = nl.item(0).getFirstChild();
17                 String cName = classNode.getNodeValue();
18                 System.out.println("类名:  "+ cName); //输出类名
19                 //通过类名生成实例对象返回
20
21             Object obj = null;
22             try {
23                 Class c =Class.forName("com.a004."+cName);
24                 obj = c.newInstance();
25             } catch (ClassNotFoundException e) {
26                 System.out.println("ClassNotFoundException");
27                 e.printStackTrace();
28             } catch (InstantiationException e) {
29                 System.out.println("InstantiationException");
30                 e.printStackTrace();
31             } catch (IllegalAccessException e) {
32                 System.out.println("IllegalAccessException");
33                 e.printStackTrace();
34             }
35             return obj;
36         } catch (Exception e) {
37             e.printStackTrace();
38             return null;
39         }
40     }
41 }

config.xml

1 <?xml version = "1.0"?>
2 <config>
3     <className>Black</className>
4 </config>

Client.java

 1 package com.a004;
 2 public class Client {
 3     public static void main(String[] args) {
 4         Color color;
 5         Man man;
 6         Woman woman;
 7         color=(Color) XMLUtil.getBean();
 8 //        color=new White();
 9         woman=color.produceWoman();
10         woman.play();
11         man=color.produceMan();
12         man.play();
13     }
14 }
