COP2800 - Java Programming Course Project
Fall 2014 Page 1 of 8 Juan López
INSTRUCTIONS:
In this project, you will create a java program to manage the
grades of one college course.
The user interface for the program will be text-menu driven.
Figure 1 depicts what the menu should look like upon launching
the program.
===============================================
=
1 - Add student to course
2 - Add exam grade for student
3 - Remove a student from course
4 - Show grades for 1 student
5 - Show grades for all students in the course
6 - Save course to file
7 - Load course from file
8 - Quit program
===============================================
=
Enter selection between 1 and 8:
Figure 1 - Menu for course program
1 - Read all instructions CAREFULLY!
The User interface is described in Section 1 of this document.

The Java Classes you must implement are described in Section
2 of this document.
2 - All programming must follow the guidelines in Appendix I
of the text book (page A-79).
3 - The Project must be submitted as a zipped Java Application
as implemented on NetBeans.
4 - The Project must be uploaded by Dec 1, 11:59 PM
(Monday).
5 - Extra credit opportunities are listed in the last page. They
are optional.
SECTION 1: USER INTERFACE
The program will behave in the following manner:
A - Menu: Menu item selection must be validated.
Upon program launching, the Menu will be drawn on the screen
(see Figure 1). If a user
enters an invalid menu number, the program must advise the
user to enter a valid
selection, and try again.
B - Menu Selections:
Selection 1 - Add Student to a course
When user selects item 1, the program asks the user for the
Student's last name, first
name, student id, and her year in college.

If the Student ID provided is not in the course, the program then
adds the student to the
course, and prints out the student’s record confirming the
addition:
Student added successfully:
Student ID: 1234
Student Name: Smith, Joan
Year in School: 4
Grades: <none>
The program will validate that a student with that ID is not
already in the course:
===============================================
=
1 - Add student to course
2 - Add exam grade for student
3 - Remove a student from course
4 - Show grades for 1 student
5 - Show grades for all students in the course
6 - Save course to file
7 - Load course from file
8 - Quit program
===============================================
=
Enter selection between 1 and 8: 1
Enter student ID: 1234
ERROR: Student ID already exists.

(hint: a new Student
object should be created,
then added to the Course
object's ArrayList of
Students).
Select 2 - Add an exam grade for a student
When user selects item 2, the program prompts the user for the
student’s id.
If there is no student with the ID entered, the program will let
the user know, and then re-
output the main menu.
If a student is found, the program will ask the user for the
grade. Grades will be between
0 and 100. The system will not hold more than 5 grades per
student.
After adding the grade, the program will print out the student’s
record, confirming the
addition of the new grade:
Student grade added successfully:
Student ID: 1234
Year in School: 4

Grades: 82
Average: 82.0
Select 3 - Remove a student from the course
student's id.
If there is a student with that id, the program prints the student
info then asks user to
confirm he wants to delete the student from the course.
Student ID: 1234
Year in School: 4
Grades: 82
Average: 82.0
Are you sure you want to delete? (Y/N):
If the user responds with a "Y", the program then deletes the
student from the course
and outputs the confirmation.
Student 1234 deleted.
(hint: the program first finds the Student that needs to be
deleted from the Course object's Student ArrayList.
Upon the user confirming, the program deletes that Student

object from the Course object's ArrayList of
Students)
Select 4 - Show grades for 1 student in the course
student's id. The
program then prints out the student's grade in the following
format:
Student record:
Student ID: 1234
Year in School: 4
Grades: 82, 94, 89
Average: 89.0
Select 5 - Show grades for all the students in the course
When the user selects item 5, the program will print a list of all
the students and their
grades in the following format:
Course roster:

ID Name Year Grades Average
---------------------------------------------------------------------------
------
1234 Lopez, Juan 3 2, 86, 98 62.00
1235 Alvarez, Jeanie 5 95 95.00
1237 Washington, Jerome 3 <no grades> 0.00
1240 Pierre, Monique 3 <no grades> 0.00
Select 6 - Save course to file
When the user selects item 6, the program will prompt the user
for the file name. The
program then saves the file in the format depicted on Figure 2.
If the file cannot be created, the program will return an error
message to the user, then
take the user back to the main menu
Figure 2 - Course file format - use the pipe (“|”) as the delimiter
1234|Lopez|Juan|3|3|2|86|98|-1|-1
1235|Alvarez|Jeanie|5|1|95|-1|-1|-1|-1
1237|Washington|Jerome|3|0|-1|-1|-1|-1|-1
Student ID
Last
Name
First
Name

Year in
School
Number of
Grades
Grades (up to 5,
-1 means no
grade exists)
Select 7 - Load course from file
When the user selects item 7, the program will prompt the user
for the name of the file to
be loaded. The file to be loaded will be of the same format
depicted in Figure 2.
If the file could not be loaded, the program will return an error
message to the user, then
outputs the main menu.
Select 8 - Quit Program
When the user selects item 8, the program prints the word
"Goodbye!", then exits.
Goodbye!

SECTION 2: JAVA CLASSES
Your java program must implement at least 3 classes as
described below.
1 - CourseUI class
The CourseUI class has the user interface to the program.
It should present all output to user and receive all input from
the user.
This class should have one
This class needs only one method - the main method.
Your solution should have much more than one method, to
make the code readable.
2 - Student class
The Student class has all information about 1 student:
last name (a string)
first name (a string)
year in school (an integer from 1 - 5)
student id (an integer between 1 and 99999)
an Array of exam scores.
each exam score is an integer from 0 - 100.
a student will have no more than 5 exam grades
The Student class should have at least the following public
methods:
Constructors:
Student(int inId, String inLastName, String inFirstName, int
inYearInSchool)
Student(String inRecordStringFromFile)
Accessors:
String getStudentName()
String getId()
String getYearInSchool()

String getGrades()
double getAverageGrade()
String getStudentFileString()
Mutators:
void setLastName(String inLastName)
void setFirstName(String inFirstName)
void setId(int inId)
void setYearsInSchool(int inYears)
void addExamScore(int inScore)
void removeExamScore(int scoreNbr)
for extra credit
SECTION 2: JAVA CLASSES (continued)
3 - Course class
The Course class has the information about the course:
an ArrayList of Student objects
name of the file (a string)
flag to know whether file has changed (a boolean)
The Course class should have at least the following public
methods:
void addStudent(in inId, String inLastName,
String inFirstName, int yearInSchool)
void removeStudent(int inStudentID)

void addScoreToStudent(int inStudentID, int inScore)
void removeScoreFromStudent(int inStudentID, int inScore)
Student getStudent(int inStudentId)
String getStudentGrades(int inStudentId)
String getAllStudentGrades()
void saveCourseToFile(PrintWriter inOutput)
void loadCourseFromFile(Scanner inFileName)
for extra credit

Extra Credit #1 - Add option to Remove an exam grade from
student
Value: 1 homework assignment
Add menu option: Remove an exam grade from a student
When user selects to remove an exam grade from a student, the
program prompts the user
for the student’s id.

If a student is found, the program will list all the grades
associated with that student and
prompt the user for the exam number to delete:
Enter student ID: 1235
Student: Lopez, Jennifer
===========
Num - Score
===========
[ 0] - 94
[ 1] - 100
Enter Quiz number: 1
About to delete [ 1] - 100
Are you Sure? (y/n) y
After removing the grade, the program will print out the
student’s record, confirming the exam
score removal:
Grade [1] deleted:
Student ID: 1235
Student Name: Lopez, Jennifer
Year in School: 5
Grades: 94
Average: 94.00
Extra Credit #2 – When the user selects Quit, if he has made
changes to the
course and has not saved, prompt him to save changes.

Extra Credit #3 – Create a version of the program in another
language.
