Implement refactored classes and draw the UML class Diagram for the following 6 classes in Java :

--------------------------------------------------------------------------------

1. university class:

import java.util.*;

public class university

{

public static void main(String[] args)

{

School engSchool = new School("Computing School");

Student s = new Student("Jason", "Fisherman", "Freshman", "CS/CSE", 3.5);

Faculty f = new Faculty("Mick", "Armstrong", "ENG", "SOA", false, 1000.00, 0);

OfficeStaff os= new OfficeStaff("Bella", "Broudy", true , 0, 20.00);

TechnicalSupportStaff ts = new TechnicalSupportStaff("Clara", "Ray" , "Database", false, 12000.50, 0);

engSchool.addstudent(s);

engSchool.addfaculty(f);

engSchool.addofficeStaff(os);

engSchool.addTSS(ts);

engSchool.displaySchoolInfo();

}

}

--------------------------------------------------------------------------------
