[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：
-
画出对应的类图；
-
提交源代码；
Adapter.java
package robot;
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 zhua(){}
public void wang(){}
public void run(){
System.out.println("A dog learns from a cat:");
cat.zhua();
}
public void cry(){
System.out.println("A cat like dog:");
dog.wang();
}
}
Cat.java
package robot;
public interface Cat {
public void cry();
public void zhua();
}
Dog.java
package robot;
public interface Dog {
public void wang();
public void run();
}
Main.java
package robot;
public class main {
public static void main(String[] args) {
Dog dog=new Adapter();
Cat cat=new Adapter();
dog.run();
cat.cry();
}
}
Realcat.java
package robot;
public class Realcat implements Cat{
public void cry(){
System.out.println("miao miao!");
}
public void zhua(){
System.out.println("Catch the mouse!");
}
}
Realdog.java
package robot;
public class Realdog implements Dog{
public void wang(){
System.out.println("wang wang!");
}
public void run(){
System.out.println("Make a run for it!");
}
}
3.注意编程规范。
