Java-马士兵设计模式学习笔记-桥接模式

一、概述

1.桥接模式的应用情况：(1)两个维度扩展(2)排列组合

二、代码

1.Gift.java

 public class Gift {

     protected GiftImpl giftImpl;
 }

2.GiftImpl.java

 public class GiftImpl {

 }

3.WarmGift.java

 public class WarmGift extends Gift {

     public WarmGift(GiftImpl giftImpl) {
         //调用父类的giftImpl
         this.giftImpl = giftImpl;
     }

     @Override
     public String toString() {
         return this.getClass().getName()+"-----"+giftImpl.getClass().getName();
     }
 }

4.WildGift.java

 public class WildGift extends Gift {

     public WildGift(GiftImpl giftImpl) {
         //调用父类的giftImpl
         this.giftImpl = giftImpl;
     }

     @Override
     public String toString() {
         return this.getClass().getName()+"-----"+giftImpl.getClass().getName();
     }
 }

5.Flower.java

 public class Flower  extends GiftImpl {

 }

6.Ring.java

 public class Ring extends GiftImpl {

 }

7.MM.java

 public class MM {

     private String name;

     public String getName() {
         return name;
     }

     public void setName(String name) {
         this.name = name;
     }

 }

8.Boy.java

 public class Boy {

     private String name;

     public void pursue(MM mm){
         Gift gift = new WildGift(new Flower());
         give(gift, mm);
         System.out.println(gift);
     }

     public void give(Gift gift, MM mm) {

     }
 }

9.Test.java

 public class Test {

     @org.junit.Test
     public void test() {
         Boy b = new Boy();
         b.pursue(new MM());
     }

 }

三、运行结果
