桥接模式8（11）

Posted 2022-09-04 zzlcome

 桥接是先有桥，才有两端的东西（可以分离某个东西）
 适配是先有两边的东西，才有适配器

public class BridatePMain 

    public static void main(String[] args) 
        BridgeP bp = new BridgePRight();
        CrossBridge cross = new CrossBridge(bp);
        cross.goRight();
    

//目的地与桥绑定
interface BridgeP
    public  void crossBridge();


//在桥右边
class BridgePRight implements BridgeP

    @Override
    public void crossBridge() 
        System.out.println("我到了桥右边");
    



abstract class BridgePLeft
    
    protected BridgeP bp;
    public BridgePLeft(BridgeP bp)
        this.bp = bp;
    
    public abstract void goRight();


class CrossBridge extends BridgePLeft

    public CrossBridge(BridgeP bp) 
        super(bp);
    
    
    @Override
    public void goRight() 
        System.out.println("我要过桥");
        bp.crossBridge();
