This involves implementing a simple university personnel management program. The program contains at least three classes: Staff, Student and Faculty. Your program stores relevant information such as university ID, name, etc. Different information is stored depending on the type of the object. For example, a student has a GPA, a faculty has a title and department (professor, mathematics). For each data member, your program must include a getter and a setter, and each class must include at least two constructors. The goal of this Project is to demonstrate the use of classes, inheritance, abstract classes, abstract methods, and method overriding.

For a student, we need a: - full name - id - gpa - Number of credit hours currently taken For a faculty, we need a: - full name - id - department (mathematics, engineering or english) - Rank (professor or adjunct) For a staff, we need a: - full name - id - department (mathematics, engineering or english) - status (part time or full time) Students in this college pay $236.45 per credit hour in addition to a $52 administrative fee. Your code should generate a tuition invoice (a method within the class Student). Note that students get a 25% off total payment if their gpa is greater or equal to 3.85.

Your code should implement the following inheritance hierarchy: Student Person Faculty Employee Staff Both classes Student and Employee inherit from the abstract class Person. The abstract class Person has what is common to a Student and an Employee (Faculty or Staff). The class Person must include: public abstract void print(); The abstract method print is overridden to: -print the fee invoice for a student. -print the information of a faculty -print the information of a staff It is left to you (the programmer) to come out with other abstract methods if you see fit (this is optional). The class Employee should also be abstract, and it is supposed to include what is common to a staff and a faculty object. Test your code with ONE array of size 100 of type Person (It must be an array, not an auravlist, linked list, hash map or anything else...). The sample run below should give you a clear idea about how your code should run. The user's entry is marked in bold so you can tell what your code should display to the screen and what the user enters. Please note well that: 1) Your code should run exactly as shown on the sample run below (However, the TA will not deduct points because you skipped two lines instead of three or your tuition invoice has 56 hyphens instead of 63 2) When asked to enter the faulty's department, mathematics and Mathematics are considered to be the same. Your program should display Mathematics if faculty information is to be displayed to the screen. However, if the user enters Mathematics department, then this is an invalid entry. Consider these departments only: Mathematics, Engineering and Sciences. As for the rank of a faculty, consider these ranks only: Professor and Adjunct. 3) The university ID has no required form so you may choose to enter anything to be the ID. 4) Your code should handle up to 5000 people (faculty, staff and students combined)
