[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。

代码按照图中顺序

package test8;

public class Adapter implements Cat,Dog{
    private Cat cat=new Realcat();
    private Dog dog=new Realdog();
    public void setcat(Cat _cat){
        cat=_cat;
    }
    public void setdog(Dog _dog){
        dog=_dog;
    }
    public void catchs(){}
    public void wang(){}
    public void run(){
        System.out.println("小狗学小猫：");
        cat.catchs();
    }
    public void miao(){
        System.out.println("小猫学小狗：");
        dog.wang();
    }
}

package test8;

public interface Cat {
    public void catchs();
    public void miao();
}

package test8;

public interface Dog {
    public void wang();
    public void run();
}

package test8;

public class Main {

    public static void main(String[] args) {
        Dog dog=new Adapter();
        Cat cat=new Adapter();
        dog.run();
        cat.miao();
    }
}

package test8;

public  class Realcat implements Cat{
    public void miao(){
        System.out.println("喵喵叫！");
    }
    public void catchs(){
        System.out.println("抓老鼠！");
    }
}

package test8;

public class Realdog implements Dog{
    public void wang(){
        System.out.println("汪汪叫！");
    }
    public void run(){
        System.out.println("跑跑跑！");
    }
}
