CSC 217 Lab 08 Implement and Test CourseRoll

The updated design contains a new package, edu.ncsu.csc216.pack_scheduler.course.roll and a new class CourseRoll.

Create edu.ncsu.csc216.pack_scheduler.course.roll Package

Create the edu.ncsu.csc216.pack_scheduler.course.roll package in the src/ folder of PackScheduler.

Create CourseRoll Class

Create CourseRoll in the src/ folder of the edu.ncsu.csc216.pack_scheduler.course.roll package.

Create CourseRollTest Class

Create CourseRollTest in the test/ folder of the edu.ncsu.csc216.pack_scheduler.course.roll package. You will need to create the edu.ncsu.csc216.pack_scheduler.course.roll package in the test/ source folder.

When testing, you may find it useful to work with the CourseCatalog and StudentDirectory objects for quickly loading and finding Courses and Students.

Implement CourseRoll State

CourseRoll has the following state:

  • roll: a custom LinkedAbstractList of Students
  • enrollmentCap: the roll’s enrollment capacity
  • MIN_ENROLLMENT: the smallest class size is 10
  • MAX_ENROLLMENT: the largest class size is 250

Test and Implement CourseRoll.CourseRoll() and CourseRoll.setEnrollmentCap()

Write a test for CourseRoll’s constructor. You should implement CourseRoll.getOpenSeats() and CourseRoll.getEnrollmentCap() to help with testing the constructor. The getOpenSeats() method returns the difference between the enrollmentCap and the size of the roll.

The constructor of CourseRoll should create an empty LinkedAbstractList of Students. The enrollmentCap should be set using setEnrollmentCap(). setEnrollmentCap() should throw an IllegalArgumentException if the enrollmentCap is less than MIN_ENROLLMENT or greater than MAX_ENROLLMENT. Additionally, the enrollmentCap can change if roll has been constructed and the new enrollmentCap is not less than the number of currently enrolled students. Add tests for setEnrollmentCap().

Test and Implement CourseRoll.enroll(Student s)

Write tests for CourseRoll.enroll(Student s).

CourseRoll.enroll(Student s) should add the Student to the end of the roll. An IllegalArgumentException is thrown if:

  • The Student is null
  • There is no more room in the class
  • The Student is already enrolled
  • If adding the student to the LinkedAbstractList generates an exception. In that case, the exception should be propagated to an IllegalArgumentException.

Test and Implement CourseRoll.drop(Student s)

Write tests for CourseRoll.drop(Student s).

CourseRoll.drop(Student s) should remove the Student from the roll. An IllegalArgumentException is thrown if:

  • The Student is null
  • If removing the student from the LinkedAbstractList generates an exception. In that case, the exception should be propagated to an IllegalArgumentException.

Test and Implement CourseRoll.canEnroll(Student s)

Write tests for CourseRoll.canEnroll(Student s).

CourseRoll.canEnroll(Student s) returns true if the Student can be added to the CourseRoll and false if:

  • There is no more room in the class
  • The Student is already enrolled

You may find it useful to use canEnroll() in CourseRoll.enroll() for the checks.
