Programming Project 2 List of students

CMSC 215 Intermediate Programming
Programming Project 2
The second programming project involves writing a program that produces a list of students who
are eligible for membership in an honor society. This program consists of four classes. The first
class is the Student class. It has three instance variables which include the student name, credit
hours earned and quality points. At a minimum, it should have following methods:
 A constructor that allows the student’s name, credit hours and quality points to be
initialized.
 A method named gpa that returns the student’s grade point average, which is computed
as the quotient of the quality points and credit hours
 A method eligibleForHonorSociety that returns whether a student’s gpa exceeds the
threshold for honor society membership, which applies to all students
 A toString method that returns a string containing the student name and grade point
average
 A class (static) method setGpaThreshold that sets the minimum gpa threshold for honor
society membership
The Student class has two subclasses. The first is Undergraduate. It has an additional instance
variable that specifies the student’s year: either a freshman, sophomore, junior or senior. At a
minimum, it should have following methods:
 A constructor that allows the student’s name, credit hours, quality points and year to be
initialized
 An overridden method eligibleForHonorSociety that applies the requirement that the
student be either a junior or senior in addition to the requirement that applies to all
students to be eligible for honor society membership
 An overridden toString method that returns a string containing the student name, grade
point average, and year
The second subclass is Graduate. It has an additional instance variable that reflects whether the
student is pursuing a master’s degree or doctorate At a minimum, it should have following
methods:
 A constructor that allows the student’s name, credit hours, quality points and degree
sought to be initialized
 An overridden method eligibleForHonorSociety that applies the requirement that the
student be seeking a master’s degree in addition to the requirement that applies to all
students to be eligible for honor society membership
 An overridden toString method that returns a string containing the student name, grade
point average, and degree sought
Finally there should be a fourth class Project2 that contains the main method. It should read in
student information from a text file named students.txt. If the file does not exist, an error
message should be displayed and the program should terminate. Each line of the text file will
represent the information for one student. An example of how the text file will look is shown
below:
Brown,William 72 230 Junior
Johnson,Mary 21 77 Masters
Jones,Sally 32 95 Sophomore
For undergraduate students, the final value is the student’s year. For graduate students, the final
value is the degree the student is seeking. As the students are read in, Student objects of the
appropriate type should be created and they should be stored in an array list of type Student. As
the students are read in, the total of all grade point averages should be accumulated so that an
average gpa can be computed. You may assume that the file that the data in the file will be
formatted correctly.
Once all the student data is read in, the threshold for honor society membership should then be
set to the midpoint of the average gpa and the highest possible gpa of 4.0 by calling the
setGpaThreshold method. The threshold should also be displayed on the console. Then a report
should be displayed on the console that lists all students who are eligible for membership .
Be sure to follow good programming style, which means making all instance variables private,
naming all constants and avoiding the duplication of code. Furthermore you must select enough
test data to completely test the program.
You are to submit two files.
1. The first is a .zip file that contains all the source code for the project. The .zip file
should contain only source code and nothing else, which means only the .java files. If
you elect to use a package, the .java files should be in a folder whose name is the
package name. Every outer class should be in a separate .java file with the same name
as the class name. Each file should include a comment block at the top containing your
name, the project name, the date, and a short description of the class contained in that
file.
2. The second is a Word document (PDF or RTF is also acceptable) that contains the
documentation for the project, which should include the following:
a. A UML class diagram that includes all classes you wrote. Do not include
predefined classes
b. A test plan that includes test cases that you have created indicating what aspects
of the program each one is testing
c. A short paragraph on lessons learned from the project
