The document outlines the design of a class structure in Java, starting with a base class named 'Person' and two subclasses 'Student' and 'Employee', with 'Faculty' and 'Staff' further subclassed from 'Employee'. It details the attributes of these classes, such as name, address, office, salary, and class status, along with a custom 'mydate' class for handling dates. Each class includes an overridden 'toString' method for displaying relevant information.

1. Java
(The Person, Student, Employee, Faculty, and Staff classes) 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, phone number, and e-mail 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. Use the MyDate class defined below to create an object for date
hired. A faculty member has office hours and a rank. A staff member has a title. Override the
toString method in each class to display the class name and the persons name.
File name: MyDate.java
//Import date package for Date class
import java.util.Date;
class MyDate {
int year; int month; int day;
public MyDate() {
long timein_Sec=System.currentTimeMillis();
Date currentDate=new Date( timein_Sec);
year=currentDate.getYear()+1900;
month=currentDate.getMonth()+1;
day=currentDate.getDate();
System.out.println("current Time HH:MM:SS "+ currentDate.getHours()
+":" +currentDate.getMinutes()+":" +currentDate.getSeconds());
}
public MyDate(int MM,int DD,int YYYY) {
year=YYYY; day=DD; month=MM;
}
public MyDate(long elapTime) {
Date userDate=new Date(elapTime);
year=userDate.getYear()+1900;
month=userDate.getMonth()+1;
day=userDate.getDate();
System.out.println("User Date Time HH:MM:SS "+ userDate.getHours()
+ ":"+userDate.getMinutes()+ ":"+userDate.getSeconds());
}
public void setDate(long elapsedTime){
Date currentDate=new Date(elapsedTime);
year=currentDate.getYear()+1900;
month=currentDate.getMonth()+1;
day=currentDate.getDate();
