Java教练和运动员，乒乓球和篮球出国打比赛，需要学英语

先创建一个包，在包中创建如下：

Person抽象类

package jiekouchouxiang;

public abstract class Person {
    private String name;
    private int age;
    public Person(){

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

    }
    public abstract void eat();
    public  void sleep(){
        System.out.println("睡觉要有足够的睡眠");
    }
    public void show(){
        System.out.println("姓名："+name);
        System.out.println("年龄："+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;
    }


}

Player抽象类

package jiekouchouxiang;

public abstract class Player extends Person {

    public  abstract  void student();


}

    }
    public abstract void teacher();
}

English接口

    void speak();
}

PingpangPlayer

    }
    @Override
    public  void eat(){
        System.out.println("乒乓球运动员要吃清淡的饭菜");

    @Override
    public void speak(){
        System.out.println("乒乓球教练要学习英语");
    }
}

BasketballPlayer

package jiekouchouxiang;

public  class BasketballPlayer extends Player {
    @Override
    public void student(){
        System.out.println("篮球运动员要学习运球和投篮技巧");

    }
    @Override
    public  void eat(){
        System.out.println("篮球教练要吃高蛋白的饭菜");
    }
}

jiekouchouxiang

package jiekouchouxiang;

public class jiekouchouxiang {
    public static void main(String[] args) {
        PingpangPlayer ppp=new PingpangPlayer();
        ppp.setName("马龙");
        ppp.setAge(18);
        ppp.show();
        ppp.eat();
        ppp.student();
