Java案例——猫狗案例加入跳高功能分析及其代码实现（面向对象）

动物类：姓名，年龄，吃饭，睡觉。

动物培训接口：跳高

猫继承动物类

狗继承动物类

部分猫继承猫类并实现跳高接口

部分狗继承狗类并实现跳高接口

代码展示：

Animal.java

Dog.java

ErhaDog.java

package demo09;/*** @Author:liger* @Description:爱学Java* @Time：-11-04 16:57*/public class ErhaDog extends Dog implements JumpInterface{@Overridepublic void eat() {System.out.println(this.getName()+"今年"+this.getAge()+"喜欢吃狗粮");}@Overridepublic void sleep() {System.out.println("二哈喜欢睡在地上");}public ErhaDog(String name,int age){super(name,age); //调用父类有参构造方法}public void door(){System.out.println(this.getName()+"在看门");}@Overridepublic void jump() {System.out.println("狗没学会跳高");}}

Tomcat.java

package demo09;/*** @Author:liger* @Description:爱学Java* @Time：-11-04 16:56*/public class Tomcat extends Cat implements JumpInterface{@Overridepublic void eat() {System.out.println(this.getName()+"今年"+this.getAge()+"tom喜欢吃鱼");}@Overridepublic void sleep() {System.out.println(this.getName()+"喜欢睡在沙发上");}public Tomcat (String name,int age){super(name,age);//调用父类有参构造方法}public void mouse(){System.out.println(this.getName()+"抓老鼠");}@Overridepublic void jump() {System.out.println(this.getName()+"学会了跳高");}}

JumpInterface.interface

public interface JumpInterface {void jump();}

Test.java

package demo09;/*** @Author:liger* @Description:爱学Java* @Time：-11-04 16:50*/public class Test { //定义测试类public static void main(String[] args) {Cat c=new Tomcat("tom",10);// 使用有参构造方法c.eat();c.sleep();Tomcat tomcat= (Tomcat) c; //向下转型tomcat.mouse();tomcat.jump();Dog d=new ErhaDog("二哈",20);//使用有参构造方法d.eat();d.sleep();ErhaDog e= (ErhaDog) d;//向下转型e.door();e.jump();}}
