[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；
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 zhua(){}
public void wang(){}
public void run(){
System.out.println("小狗学小猫：");
cat.zhua();
}
public void cry(){
System.out.println("小猫学小狗：");
dog.wang();
}
}
package test8;
public interface Cat {
public void cry();
public void zhua();
}
package test8;
public interface Dog {
public void wang();
public void run();
}
package test8;
public class Realcat implements Cat{
public void cry(){
System.out.println("喵喵叫！");
}
public void zhua(){
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("快快跑！");
}
}
package test8;
public class main {
public static void main(String[] args) {
Dog dog=new Adapter();
Cat cat=new Adapter();
dog.run();
cat.cry();
}
}
3.注意编程规范。
