Person Student Employee Faculty Staff 类

实现一个名为Person的类和它的两个子类Student和Employee

Employee有子类Faculty和Staff。Person中的人有姓名、地址和电话号码。

学生有班级状态（一、二、三、四年级）。将这些状态定义为常量。

Employee中的雇员有办公室、工资。Faculty中的教员有级别。

Staff中的职员有职务称号。覆盖每个类中的toString方法，显示类名和各类中的各个属性。

public class Person
{
String Name;
String Address;
static String Tel;

public Person()
{
}

public Person(String Name,String Address,String Tel)
{
this.Name = Name;
this.Address = Address;
Person.Tel = Tel;
}

public String toString()
{
return "姓名："+Name+"类名："+"Person";
}
}

public class Student extends Person
{
 int class_Num;

public Student()
{

}

public Student(String Name,String Address,int class_Num)
{
super(Name,Address,Tel);
this.class_Num = class_Num;
}

public String toString()
{
return "姓名："+Name+"类名"+"Student";
}
}

public class Employee extends Person {


String Office;
double Salary;

public Employee()
{

}

public Employee(String Name,String Tel,String Address,String Office,double Salary)
{
super(Name,Address,Tel);
this.Office = Office;
this.Salary = Salary;
}

public String toString()
{
return "姓名："+Name+"类名"+"Employee";
}
}

public class Faculty extends Employee{
String Level;

public Faculty()
{

}

public Faculty(String Name,String Tel,String Address,String Office,double Salary,String Level)
{
super(Name,Tel,Address,Office,Salary);
this.Level = Level;

}

public String toString()
{
return "姓名："+Name+"类名"+"Faculty";
}
}

public class Staff extends Employee
{
String Post;

public Staff()
{

}

public Staff(String Name,String Tel,String Address,String Office,double Salary,String Post)
{
super(Name,Tel,Address,Office,Salary);
this.Post = Post;
}

public String toString()
{
return "姓名："+Name+"类名"+"Staff";
}
}

测试类：

public class Staff extends Employee
{
String Post;

public Staff()
{

}

public Staff(String Name,String Tel,String Address,String Office,double Salary,String Post)
{
super(Name,Tel,Address,Office,Salary);
this.Post = Post;
}

public String toString()
{
return "姓名："+Name+"类名"+"Staff";
}
}

运行结果：

姓名：张天宇类名：Person
姓名：楼听雨类名：Person
姓名：刘高类名Employee
姓名：丽丽类名Faculty
姓名：胡歌类名Staff
