 1 /**

 6 public class LeiFeng {
 7 
 8     public void Sweep(){
 9         System.out.print("\\t扫地\\t");
10     }
11     
12     public void Laundry(){
13         System.out.print("\\t洗衣\\t");
14     }
15     
16     public void Cook(){
17         System.out.print("\\t做饭\\t");
18     }
19 }

LeiFeng.java

1 /**
2  * 工厂接口

6 public interface IFactory {
7 
8     LeiFeng createLeiFeng();
9 }

IFactory.java

 1 /**
 2  * 学习雷锋的人

 6 public class UndergraduateFactory implements IFactory {
 7 
 8     @Override
 9     public LeiFeng createLeiFeng() {
10         return new Undergraduate();
11     }
12     
13 }

UndergraduateFactory.java

1 /**
2  * 志愿者
3  * @author lucksheep
4  *
5  */
6 public class Undergraduate extends LeiFeng {
7 
8 }

Undergraduate.java

1 public class VolunteerFactory implements IFactory {
2 
3     @Override
4     public LeiFeng createLeiFeng() {
5         return new Volunteer();
6     }
7 
8 }

VolunteerFactory.java

1 /**
2  * 志愿者
3  * @author Administrator
4  *

6 public class Volunteer extends LeiFeng {
7 
8 }

Volunteer

 1 /**

 3  * 场景：学雷锋做好事
 4  * 角色：大学生、志愿者等
 5  * 行为：扫地、洗衣、做饭等

 9 public class Test {
10 
11     public static void main(String[] args) {
12         
13         IFactory ifactory=new VolunteerFactory();
14         LeiFeng lf=ifactory.createLeiFeng();
15         
16         lf.Sweep();
17         lf.Cook();
18         lf.Laundry();
19         
20     }
21 
22 }

Test.java

结果：

额个人理解啥的就不说了，这些都是看文档后按照上面打的，边学边用，在实际开发中还是很好用的............................
