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
