JAVA作业求解答

Question

2、动物园仿真系统
(1) 抽象类动物：实例变量名字和体重，构造方法，和无返回值的抽象方法feed(int time)，以及实例变量的访问和修改方法
(2) 子类狮子：实现抽象方法，控制台输出“狮子一天吃肉”+time +”次”
(3) 子类熊猫：实现抽象方法，控制台输出“熊猫一天吃竹子”+time+”次”
(4)测试类：主函数使用抽象类创建狮子和熊猫，并执行抽象方法feed

abstract class animalTest {

public abstract void feed(int time);

public animalTest(String name, double weight) {

}
}

class lion extends animalTest{

public lion(String name, double weight) {
super(name, weight);
}

@Override

@Override

public class animal{
public static void main(String[] args) {
animalTest lion = new lion("辛巴",500);
animalTest panda = new panda("阿宝",300);
lion.feed(3);
panda.feed(4);
