Animal类：

package saobi;

public abstract class Animal {
    private String name;
    private int age;

    public Animal() {
    }

    public Animal(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
    public abstract void eatfood();
}

Cat类：

package saobi;

public class Cat extends Animal implements Jumpping{
    public Cat() {
    }

    public Cat(String name, int age) {
        super(name, age);
    }

    @Override
    public void eatfood() {
        System.out.println("猫吃鱼");
    }

    @Override
    public void Jumpping() {
        System.out.println("猫可以跳高了");
    }
}

Dog类：

package saobi;

public class Dog extends Animal implements Jumpping{
    public Dog() {
    }
    public Dog(String name,int age){
        super(name,age);
    }

    @Override
    public void eatfood() {
        System.out.println("狗吃骨头");
    }

    @Override
    public void Jumpping() {
        System.out.println("狗可以跳高了");
    }
}

Jumpping接口：

package saobi;

public interface Jumpping {
    public abstract void Jumpping();
}

AnimalDemo类：

package saobi;

public class AnimalDemo {
    public static void main(String[] args) {
        Jumpping j = new Cat();
        j.Jumpping();
        System.out.println("----------");
        Animal a = new Cat();
        a.setName("黑网猫");
        a.setAge(5);
        System.out.println(a.getName() + "," + a.getAge());
        a.eatfood();
a=new Cat("加菲",18);
        System.out.println(a.getName()+","+a.getAge());
        a.eatfood();
        System.out.println("--------");
        Cat c=new Cat();
        c.setName("佳佳");
        c.setAge(22);
        System.out.println(c.getName()+","+c.getAge());
        c.eatfood();
        c.Jumpping();
    }
}
