无论什么时候不要去继承一个已经完成好的类！

package com.yikuan.cn;

//定义一个抽象类

abstract class Person{

private int age;

private String name;

//构造方法

public Person(int age,String name){

this.age = age;

this.name = name;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

//抽象方法

public abstract void want();

}

//创建一个学生类

class Student extends Person{

private int score; //成绩

public int getScore() {

return score;

}

public void setScore(int score) {

this.score = score;

}

//重写父类中的构造方法

@Override

public void want() {

System.out.println("姓名："+getName()+" 年龄"+getAge()+" 成绩"+getScore());

}

//构造方法

public Student(int age, String name, int score) {

super(age, name);

this.score = score;

}

}

//创建一个工人类

class Worker extends Person{

private int money;

public int getMoney() {

return money;

}

public void setMoney(int money) {

this.money = money;

}

@Override

public void want() {

System.out.println("姓名："+getName()+" 年龄"+getAge()+" 工资"+getMoney());

}

public Worker(int age, String name, int money) {

super(age, name);

this.money = money;

}

}

public class Test1 {

public static void main(String[] args) {

//实例化学生类

Student student = new Student(10, "小明", 100);

student.want();

Worker worker = new Worker(35, "小明爸", 1000);

worker.want();

}

}
