实验8：适配器模式

本次实验属于模仿型实验，通过本次实验学生将掌握以下内容：

1、理解适配器模式的动机，掌握该模式的结构；

2、能够利用适配器模式解决实际问题。

 

[实验任务一]：双向适配器

实现一个双向适配器，使得猫可以学狗叫，狗可以学猫抓老鼠。

实验要求：

1.  画出对应的类图；

 

2.  提交源代码；

ICat.java

package shipeiqi;

 

public interface ICat {

 

    public void eat();

    public void catLook();

   

}

 

IDog.java

package shipeiqi;

 

public interface IDog {

   

    public void wang();

    public void dogLook();

 

}

 

DogImpl.java

package shipeiqi;

 

public class DogImpl implements IDog{

    

    public void dogLook() {

        // TODO Auto-generated method stub

        System.out.println("狗的样子");

    }

 

    public void wang() {

        // TODO Auto-generated method stub

        System.out.println("狗汪汪叫");

    }

 

}

 

CatImpl.java

package shipeiqi;

 

public class CatImpl implements ICat{

    

    public void catLook() {

        // TODO Auto-generated method stub

        System.out.println("猫的样子");

    }

 

    public void eat() {

        // TODO Auto-generated method stub

        System.out.println("猫抓老鼠");

    }

 

}

 

Adapter.java

package shipeiqi;

 

public class Adapter implements ICat,IDog{

 

    private IDog DogImpl = null;

    private ICat CatImpl = null;

   

    /*public Adapter(IDog DogImpl ) {

        // TODO Auto-generated constructor stub

        this.DogImpl = DogImpl;

    }

    public Adapter(ICat CatImpl) {

        // TODO Auto-generated constructor stub

        this.CatImpl = CatImpl;

    }*/

   

   

    public Adapter(IDog DogImpl,ICat CatImpl) {

        // TODO Auto-generated constructor stub

        this.DogImpl = DogImpl;

        this.CatImpl = CatImpl;

    }

    @Override

    public void dogLook() {

        // TODO Auto-generated method stub

        System.out.println("狗模仿");

        CatImpl.catLook();

    }

 

    @Override

    public void wang() {

        // TODO Auto-generated method stub

        System.out.println("狗模仿");

        CatImpl.eat();

    }

 

    @Override

    public void catLook() {

        // TODO Auto-generated method stub

        System.out.println("猫模仿");

        DogImpl.dogLook();

    }

 

    @Override

    public void eat() {

        // TODO Auto-generated method stub

        System.out.println("猫模仿");

        DogImpl.wang();

    }

   

   

}

Client.java

package shipeiqi;

 

public class Client {

   

    public static void main(String[] args) {

        Adapter adapter = new Adapter(new DogImpl(),new CatImpl());

 

        adapter.catLook();

        adapter.eat();

 

        System.out.println("**************");

 

        adapter.dogLook();

        adapter.wang();

    }

 

}

3.注意编程规范。
