java小程序，多态报错
package com.wangsufu;
public class Doutai_2 {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Master master = new Master();
master.feed(new Cat(), new Fish());
}
}
class Animal
{
public void eat()
{
System.out.println("不知道吃啥");
}
}
class Cat2 extends Animal{
public void eat()
{
System.out.println("猫吃鱼！");
}
}
class Dog2 extends Animal
{
public void eat()
{
System.out.println("狗吃骨头！");
}
}
class Food{
public void showname()
{
System.out.println("...");
}
}
class Bone extends Food
{
public void showname()
{
System.out.println("我是骨头");
}
}
class Fish extends Food
{
public void showname()
{
System.out.println("我是鱼");
}
}
class Master{
public void feed(Animal an,Food f)
{
f.showname();
an.eat();
}
}
报错如下：
The method feed(Animal, Food) in the type Master is not applicable for the arguments (Cat, Fish)
[解决办法]
哪了你的cat类了?哪了你的dog类了?
不是叫cat2吗?
