You may find the following hierarchy useful when you code your classes. A fee invoice for an MS student should look like VALENCE COLLEGE ORLANDO FL 10101 The purpose of this project is to create a fee invoice application for students attending Valence College, a college in the State of Florida. There are two types of students: graduate (PhD and MS) and undergraduate. An out- of-state undergraduate student pays twice the tuition of a Florida-resident undergraduate student (all pay the same health and id fees of $35). A graduate student is either an PhD or an MS student. PhD students don't take any courses, but each has an advisor and a research subject. Each Phd student must supervise at least one lab. A lab can be supervised by more than one PhD student (Labs can't be supervised by undergraduate students nor MS students). MS students can only take graduate courses, and undergraduate students can only take undergraduate courses. At this time, Valence College offers the following list of classes/labs: (Use it in your project as lect.txt). 89745, COT6578, Advanced Computer theory, Graduate, F2F, PSY-108, No, 4 66636, DIG2158, Introduction to Digital Systems, Undergraduate, Online, 3 32658, COT6578, Advanced Computer theory, Graduate, Mixed, LPS-35, No, 4 69745, COP5698, Programming Languages, Graduate, F2F, CB2-122, YES, 5 19745, MSB-123 36598, PSY-100 20315, HSA1-116 56980, CDL2587, Introduction to Computers, Undergraduate, F2F, MSB-116, YES, 4 98123, RMA-008 91862, RMA-008 95315, RMA-008 36636, SOF2058, Introduction to Software, Undergraduate, Online, 3 12658, LOG5578, Logic and Proof, Graduate, Mixed, LPS-35, Yes, 3 98103, CMA-008 90862, RMA-013 95310, RMA-028 60045,COP5690, Programming Languages II, Graduate, F2F, CB2-120, YES, 4 19005, MSB-103 30008, PSY-107 20300, HSA1-16 51180, CDL2587, Introduction to Computers, Undergraduate, online, 3 36637, SOF2058, Introduction to Software, Undergraduate, Online, 3 22658, LOG5578, Logic and Proof, Graduate, F2F, LPS-35, Yes, 3 98000, CMA-008 94442, RMA-013 56510, RMA-028 69970, GOL1091, Introduction to AI, Graduate, Online, 1 An explanation on how to read the list above is provided at the end of this document.

Undergraduate Students with gpa of 3.5 or higher receive a discount of 25% when the total payments exceed $500. PhD students pay a separate research fee of $700. Phd students who supervise two labs are given a discount of 50%, and PhD Students supervising 3 labs or more pay the health and id fees only.

(Student, Graduate Student, Undergraduate Student, MsStudent and PhdStudent). Both Student and Graduate Student are to be made. abstract. The Student class must contain the abstract method: abstract public void printInvoice(); Additional classes may be added. See 6) below 2) The abstract method, printInvoice, is to be overridden to display the right fee invoice, depending on the type of the student. Data fields of all classes are to be made private. 3) You may use any data structure to store your objects. That is: you may use an array, array list, LinkedList ...etc. 4) Your code should handle ALL exceptions. The bottom line is that your code should NOT crash! 5) Your code must have a user-defined exception class called IdException that handles the ids entered by the user. Note that an person's ID must be of the form LetterLetterDigit Digit Digit Digit like er7894. No two persons can have the same id. An exception of type IdException is thrown when the id entered is either duplicated or in wrong format. Handle that anyway you see fit! 6) This project requires additional code to manage the courses and labs. Note that the Java classes and data stuctures needed to manage the courses/Labs is left to you (the student) to decide on... 7) The main menu of your programs has two options: Student Management and Class Management. The Student Management option shows a sub- menu that allows the user to: Sample Run: Assume that the user enters a valid menu option (for all the menus) Student Management Main Menu 1 2 Course Management 0: Exit Enter your selection: 2 Course Management Menu: Choose one of: Course Management Menu: Choose one of: B Course Management Menu: Choose one of: A Search for a class or lab using the class/lab number delete a class C Add a lab to a class A B Search for a class or lab using the class/lab number delete a class x Back to main menu C Add a lab to a class x Back to main menu Enter your selection: c a. add a student b. search for a student by id c. delete a student d. print the fee invoice of a student by id. e.

Understanding the structure of lec.txt

Each line in lec.txt represents a class being offered at Valence College.

A class is either a lecture (LEC) or a lab (LAB). A lecture (LEC) is characterized by:

- Class Number (CN), a unique five-digit number assigned for each lecture/lab

- Prefix (like COP3330)

- Title (like Introduction to Object Oriented Programming)

- Location (like CB 2-201)

- Graduate or undergraduate.

- Modality: Online, Face-to-Face(F2F) or Mixed Mode (Mixed)

- If Modality is F2F or Mixed, then the following entry is the location where that

class is taking place. The next YES/NO field is to specify whether that class

has a lab or not. When a non-online class has a lab, the labs are listed right

after. See below for more information about the labs. Online sections don’t have

labs.

- Credit hours is the last field of any lecture.

Examples:

89745,COT6578,Advanced Computer theory,Graduate,F2F,PSY-108,No,4

32658,COT6578,Advanced Computer theory,Graduate,Mixed,LPS-35,No,4

That means that the college offers two sections of COT6578, one is F2F and the other

is online. Both of those sections don’t have labs.

When a lecture has a lab, the labs’ information is provided

right after the lecture information

Example:

69745,COP5698, Programming Languages,Graduate,F2F,CB2-122,YES,4

19745,MSB-123

36598,PSY-100

20315,HSA1-116

That means the COP5698 with cn 69745 has three labs. 19745, 36598 and 20315 are the

cns of the labs. MSB-123, PSY-100 and HSA1-116 are the building-room numbers where

those labs are scheduled to take place.

Note that if the Modality is Online, then the line of the

lec.txt has the form:

CN,PREFIX,LECTURE TITLE,GRADUTE/UNDERGRADUTE/ONLINE,CREDIT HOURS

Example:

36636,SOF2058,Introduction to Software,Undergraduate,Online,3
