[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. 对应的类图：
2. 源代码：
Cat接口：
public interface Cat {
void cry();
void catchMouse();
}
实体Cat类：
public class ConcreteCat implements Cat{
@Override
public void cry() {
System.out.println("猫叫");
}
@Override
public void catchMouse() {
System.out.println("猫抓老鼠");
}
}
适配器类：
public class Adapter implements Dog,Cat{
private Cat cat;
private Dog dog;
public Cat getCat() {
return cat;
}
public void setCat(Cat cat) {
this.cat = cat;
}
public Dog getDog() {
return dog;
}
public void setDog(Dog dog) {
this.dog = dog;
}
@Override
public void cry() //猫学狗叫
{
System.out.print( "猫学");
dog.wang();
}
@Override
public void catchMouse() {
cat.catchMouse();
}
@Override
public void wang() {
dog.wang();
}
@Override
public void action() //狗学猫抓老鼠
{
System.out.print( "狗学");
cat.catchMouse();
}
}
}
Test测试类
public class Test {
public static void main(String args[])
{
Cat cat1 = new ConcreteCat();
Dog dog1 = new ConcreteDog();
Adapter A1 = new Adapter();
A1.setCat(cat1);
A1.setDog(dog1);
cat1 = (Cat) A1;
cat1.catchMouse();
cat1.cry();
dog1 = (Dog) A1;
dog1.action();
}
