今天做了抽象工厂模式--人与肤色的实验，最终成功运行成功人与肤色的代码；
下面是操作流程和步骤：
[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；
Java:
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("我是黑种男人!");
}
}
public class BlackSkinWomen implements Women
{
public void play()
{
System.out.println("我是黑种女人!");
}
}
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("我是白种男人!");
}
}
public class WhiteSkinWomen implements Women{
public void play()
{
System.out.println("我是白种女人!");
}
}
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();
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();
//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("我是黄种男人!");
}
}
public class YellowSkinWomen implements Women{
public void play()
{
System.out.println("我是黄种女人!");
}
运行截图：
