JAVA代码主人喂宠物吃东西狗只吃骨头猫只吃鱼求代码用多态
/*
animal是个抽象方法java代码给宠物喂食，Cat 和Dog extends 这个就是用java代码给宠物喂食的多态
*/
package Test;
public class Test{
public static void main(String[] args){
Feeder feeder = new Feeder();
feeder.feedAnimals();

Q1: java程序 一个主人有两只宠物,一条狗一只猫,狗叫旺财，猫叫小花，分别给宠物喂食
public class Person {
public static void main(String args[]) {
Animal a1 = new Animal("猫","小花","鱼");
Animal a2 = new Animal("狗","旺财"，"骨头");
a1.eat();a2.ert();
}
}
class Animal {
String species;
String animalName;
String foodName;
Animal(String species,String animalName,String foodName) {
this.species = species;
this.animalNam e= animalName;
this.foodName = foodName;
}
public void eat() {
System.out.print("我的"+species+","+animalName +" 吃了 ："+foodName);
}
}
//我也才学java不到一个月，我就能理解这么多
//还可以写继承的。亦可以写成多线程的。
//继承就是把Animal类当父类，再写两个类继承它。这里又可以复习多态，哈哈。
//多线程就是同事喂这俩动物。
