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:

 

实验要求:

1. 画出对应的类图;

 

2.提交源代码;

public class BlackFactory implements MWFactory
{
 public Man produceMan()
 {
  return new BlackSkinMan();
 }
 
 public Women produceWomen()
 {
  return new BlackSkinWomen();
 }
}

 

public class BlackSkinMan implements Man
{
 public void play()
 {
  System.out.println("黑色皮肤的男人出现");
 }
}

 

public class BlackSkinWomen implements Women
{
 public void play()
 {
  System.out.println("黑色皮肤的女人出现");
 }
}

 

public class Client
{
 public static void main(String args[])
 {
         try
         {
          MWFactory factory;
          Man m;
          Women w;
          factory=(MWFactory)XMLUtil.getBean();
          m=factory.produceMan();
          m.play();
          w=factory.produceWomen();
          w.play();
         }
         catch(Exception e)
         {
          System.out.println(e.getMessage());
         }
 }
}

 

public interface Man
{
 public void play();
}

 

public interface MWFactory
{
 public Man produceMan();
 public Women produceWomen();
}

 

public class WhiteFactory implements MWFactory
{
 public Man produceMan()
 {
  return new WhiteSkinMan();
 }
 
 public Women produceWomen()
 {
  return new WhiteSkinWomen();
 }
}

 

public class WhiteSkinMan implements Man
{
 public void play()
 {
  System.out.println("白色皮肤的男人出现");
 }
}

 


public class WhiteSkinWomen implements Women{
  public void play()
  {
   System.out.println("白色皮肤的女人出现");
  }
 
}

 

public interface Women
{
 public void play();
}

 

import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.xml.sax.SAXException;
import java.io.*;
public class XMLUtil
{
//该方法用于从XML配置文件中提取具体类类名,并返回一个实例对象
 public static Object getBean()
 {
  try
  {
   //创建文档对象
   DocumentBuilderFactory dFactory = DocumentBuilderFactory.newInstance();
   DocumentBuilder builder = dFactory.newDocumentBuilder();

   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();
           
            //通过类名生成实例对象并将其返回
            Class c=Class.forName(cName);
        Object obj=c.newInstance();
            return obj;
           }  
            catch(Exception e)
            {
             e.printStackTrace();
             return null;
            }
  }
}

 

public class YellowFactory implements MWFactory
{
 public Man produceMan()
 {
  return new YellowSkinMan();
 }
 
 public Women produceWomen()
 {
  return new YellowSkinWomen();
 }
}

 

public class YellowSkinMan implements Man
{
 public void play()
 {
  System.out.println("黄色皮肤男人出现");
 }
}

 


public class YellowSkinWomen implements Women{
 public void play()
 {
  System.out.println("黄色皮肤的女人出现");
 }
}
