COP 3330 Project 3 Solution

Please read this entire statement carefully before you start doing anything…

This project is similar to the previous one. It involves implementing a simple university personnel management program. The program contains two different kinds of objects: students and faculty. For each object, the 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, while a faculty has a title and department (professor, mathematics).

For each of any class data member, your program must include the getters and the setters, and each class must include at least two constructors. The goal of this Project is to demonstrate the use of inheritance, abstract classes or interfaces, abstract methods and method overriding. 


Student class has:
    • Full name 
    • ID
    • Gpa
    • Number of credit hours currently taken


Faculty class has:
    • Full name
    • ID
    • Department (mathematics, engineering, arts and science)
    • Rank (professor, adjunct)


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.
Both classes Faculty and Student inherit from the abstract class Person. The abstract class Person has what’s common to both Faculty and Student, and it is left to you (the programmer) to come out with an abstract method that you implement in your classes Faculty and Student, say void printInfo();

You may change the class Person to an interface to be implemented by Faculty and Student. Either way is fine!

Your code should handle any Input Mismatch Exceptions. In addition, you code must have a user-defined exception called IdException that handles the faculty and student ids entered by the user. Note that any id has to be of the form LetterLetterDigitDigitDigitDigit like el7894. See sample run below.

Test your code with one array of size 100 (or ArrayList) of type Person. 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 enter the faulty department, matheMatics and MathematiCs are  considered to be the same, and 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. 
    3) The university ID has no required form so you may choose to enter anything to be the ID.

Goodbye!

OPTIONAL: You may try having something like:
class Faculty extends Person implements SomeInterface
class Student extends Person implements SomeInterface

But the issue is how can you have one array to manage both the Faculty and Student objects? If you are interested, please give me a call (321) 900-1696 and we’ll chat about a possible solution.
