Write a test program that creates a Person , Student , Employee , Faculty , and Staff , and invok

    Design a class named  Person and its two subclasses named  Student and Employee .Make  Faculty and  Staff subclasses of  Employee . A person has a name,address, phonenumber, and email address. A student has a class status (freshman,sophomore,junior, or senior). Define the status as a constant. An employee has an office,salary, and date hired. A faculty member has office hours and a rank. A staffmember has a title. Override the toString method in each class to display the class name and the person’s name.

    Write a test program that creates a Person , Student , Employee , Faculty , and  Staff , and invokes their  toString() methods.

public class Person {String name;  String address;  String telphone;  public Person(String n,String a,String t){   name=n;   address=a;   telphone=t;  }  public String toString(){   return name+" Person";    }public void display(Person person){System.out.println(person);}}

public class Employee extends Person{String office;double salary;public Employee(String n,String a,String t,String o,double s){super(n, a, t);office = o;salary = s;}public String toString(){return name+"employee";}}

public class Student extends Person{final String class1="一年级";final String class2="二年级";final String class3="三年级";    final String class4="四年级";    public Student(String n,String a,String t)    {     super(n, a, t);    }     public String toString()    {     return name+" Student";    }}

public class Faculty extends Employee{int Level;public Faculty (String n,String a,String t,String o,double w,int level) {super(n, a, t, o, w);Level = Level;}public String toString(){return name+"Faculty";}}
public class Staff extends Employee{String position;public Staff(String n,String a,String t,String o,double w,String p){super(n,a,t,o,w);position=p;}public String toString(){return name+"staff";}}

public class Test {public static void main(String[] args) {Person p = new Person("网", "数据库的","2345678" );p.display(p);Student s = new Student("王宏","河南省漯河市","15839652309");s.display(s);Employee e = new Employee ("李四","河南省漯河市","0395112222","人事局",222.00);e.display(e);Faculty f = new Faculty("明明", "河北", "11232312", "帮手", 234,1);f.display(f);Staff sta = new Staff("红红","河南省周口市","13849472334","人事科",345.00,"副局长");sta.display(sta);}}
