适配器模式java

[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！");
}
}
