java设计一个名为person的类和它的两个名为student和employee的子类

person，student，employee，faculty和staff类，设计一个名为person的类和它的两个名为student和employee的子类。employee类又有子类：教员类faculty和职员类staff。每个人都有姓名，地址电话号码和电子邮件地址。学生有班级状态。將这些常量定义为变量。—–java语言程序设计11.2

这里没有把常量定义为变量而是输入任意值

import java.util.*;
public class eleven112 {
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
System.out.print("student or employee?0 or 1:");
if(input.nextInt()==0) {
System.out.print("enter the classstate:");
student a=new student();
String classstate=input.nextLine();
a.setclasstate(classstate);
input.nextLine();
System.out.print("enter the name address tel email:");
String name=input.nextLine();
String address=input.nextLine();
String tel=input.nextLine();
String email=input.nextLine();
person b=new person();
b.setall(name, address, tel, email);
System.out.println("classstate: "+a.get()+b.toString());
}
else {
System.out.print("enter salary: ");
double salary=input.nextDouble();
input.nextLine();
System.out.print("enter office ");

String office=input.nextLine();

staff c =new staff();
c.em(office, salary);
System.out.print("enter the chenghao:");
c.chenghao=input.nextLine();
person d=new person();
System.out.print("enter the name address tel email:");
String name=input.nextLine();
String address=input.nextLine();
String tel=input.nextLine();
String email=input.nextLine();
d.setall(name, address, tel, email);
System.out.println(d.toString());
System.out.println(c.toString());

}

}
}

class student extends person{
private String classstate;
public void setclasstate(String classtate) {
this.classstate=classtate;
}
public String get() {
return classstate;
}
}
class employee extends person{
String office;
double salary;
public void em(String office,double salary) {
this.office=office;
this.salary=salary;
}
public String get() {
return "office: "+office+"salary: "+salary;
}

}
class staff extends employee{
String chenghao;
public String toString() {
return "office:"+super.office+"salary: "+super.salary+"称号："+chenghao;
}

}
class person{
String name,address,tel,email;
public void setall(String name,String address,String tel,String email) {
this.name=name;
this.tel=tel;
this.address=address;
this.email=email;

}
public String toString() {
return "name: "+name+"address: "+address+"tel: "+tel+"email: "+email;
