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
