刚学这方面的，很多基本的都不会,对这个题目没信心，晚上10点来核对答案，我不是不动手，现在正在做着，只是为保明天考试能通过，麻烦各位给出下面的题目正确答案，谢谢

编程：
1．    编写Person类，该类包含：
四个受私有属性：人的姓名name、年龄age、地址address和电话tel。
一个构造器方法：用于初始化name、 age和address属性。
两个公有成员方法：分别实现人基本信息的输出和设置电话。
2.编写学生类Student继承于Person类
  增加成员变量学校school、学号id
  重写父类输出方法，将学生所有信息输出。
  实例化一个对象，并输出其信息。
3.扩展：编写教师类Teacher继承于Person类
  增加成员变量学校school、编号id、职称。

class Person {
   String name;
   int age;
   String address;
   int tel;
}
class Student extends Person{
    String school;
    int id;
}
class Teacher extends Person{
    String school;
    int id;
    String career;
}
public class test{
    public static void main(String args[]){
        Student student=new Student();
        student.name="张三";
        student.age=20;
        student.address="北京";
        student.tel=888168;
        student.school="清华";
        student.id=88;
        System.out.println(student.name);
        System.out.println(student.age);
        System.out.println(student.address);
        System.out.println(student.tel);
        System.out.println(student.school);
        System.out.println(student.id);
        Teacher teacher=new Teacher();
        teacher.name="李四";
        teacher.age=29;
        teacher.address="北京";
        teacher.tel=123456;
        teacher.school="清华";
        teacher.id=22;
        teacher.career="教师";
        System.out.println(teacher.name);
        System.out.println(teacher.age);
        System.out.println(teacher.address);
        System.out.println(teacher.tel);
        System.out.println(teacher.school);
        System.out.println(teacher.id);
        System.out.println(teacher.career);
    }

帮你修改了代码，按JAVABEAN规范写的，祝你考试成功

怎么感觉我也做个这个题啊?
