Tiny college has asked you to be a part of their team because they need a programmer, analyst, and designer to help them in implementing a model of a human resources management system. In your model, you will have departments objects (representing departments). A department contains lists of teachers (either part-time or full-time teachers) and list of staffs; each of which belonging exclusively to one department. A department has a dean, who should be a teacher of that department. Implementation Details 1. Implement an abstract class Person that includes at least five shared fields and contains at least one abstract method of your choice (for example to define a person's category (teacher or staff)). 2. Extend class Person with concrete classes, and override the toString() and equals() methods of each class. 3. The class Teacher has two instance variables: speciality and degree and some other fields for its subclasses (part-time or full-time teachers) 4. The class Staff has also two instance variables: duty and workload 5. Implement an interface PayRoll that contains ComputePayRoll() method to be implemented as follows: a. For each full-time teacher, the salary is computed as (32* degreeRate * 2) * 0.85, where degreeRate is 112, 82, 42 for PhD, Master, and Bachelor, respectively. b. For each part-time teacher, the salary is computed as (hoursWorked * degreeRate *2) * 0.76, where degree Rate is 112, 82, 42 for PhD, Master, and Bachelor, respectively. c. For each staff, the salary is computed as (workload * 32 * 2) * 0.75, where workload is the weekly working hours. The working hours cannot exceed 40. d. Implement the method ComputePay Roll() inside Teacher and Staff classes.

Question

Classes should be Department, Staff, Teacher, Part-time, Full-time, abstract Person and interface Payroll

7. Trying to add a teacher or a staff member to an inexistent department (based on department id) should rise/throw an exception. 8. Trying to add a teacher or a staff member that already exists/ added (based on the id) to department should throw an exception. 9. A department class has a list of teachers and staff. A department class also has a dean, who should be a teacher of that department, otherwise an exception must be thrown. 10. Each new teacher and staff added to a department should be stored to the text file before exiting the application, generating a new version of the text file. So, if the text file does exist (which is the case), new teachers or staffs should be appended. There are files of teachers and staffs. 11. The customized exceptions handling for the cases above must be implemented. 12. Test sets should be generated for testing the effectiveness of each method in your model.

Moreover, new teachers and staff must be added/assigned through the GUI application.
