CSC 217 Lab 08 Integrate into `Course` and Related Classes

Now that the CourseRoll is complete, the Course class should use it keep track of a Course’s roll. This will require the use of a new parameter when constructing Course: enrollmentCap. Additionally, the enrollmentCap should be stored with a course record. That means an update to CourseRecordIO, CourseCatalog, and the associated test files to add the enrollment capacity value.

Integrate `CourseRoll` into `Course`

Follow the provided design to integrate CourseRoll into the Course class. You’ll add the parameter, roll and the method getCourseRoll().

You should construct the CourseRoll in the Course constructor(s). This will require a new parameter, enrollmentCap, which should follow the instructorId parameter. For the moment, this will break CourseRecordIO, CourseCatalog, and various tests. Work through the changes carefully as outlined below.

Additionally, update or add the following methods in Course:

Update Course.toString() to include the enrollmentCap from roll after the instructorId in the comma separate value string.
Update Course.getShortDisplayArray() to include a 5th element (index 4) containing the open seats in the Course’s CourseRoll.
Add the getCourseRoll() method. It should return a CourseRoll object.

Once Course compiles, update your test cases to include a value for the enrollmentCap parameter. You’ll need to change all test files that construct a Course object to use an enrollmentCap.

You should also add test cases for:

Ensuring a correct enrollmentCap or that an IllegalArgumentException is thrown if the enrollmentCap is out of bounds as described in the requirements.
Ensuring that you updates to the toString() method is correct.
Ensuring that the getShortDisplayArray() is now returning an array of length 5 and the contents are correct.

Run your Course tests in isolation. Once they compile, and you update as described above, they should pass with no regressions.

Update `CourseRecordIO` and `CourseRecordIOTest`

Now that there is an enrollment cap, you should update your test files for CourseRecordIO. Download new copies of the CourseRecordIOTest files:

Update the CourseRecordIO.readCourse() method to handle the enrollmentCap in a line of input. You may also need to update CourseRecordIOTest if you have any calls to the Course constructor.

Once CourseRecordIO and CourseRecordIOTest compile, run CourseRecordIOTest in isolation. The tests should pass with no regressions.

Update `CourseCatalog` and `CourseCatalogTest`

CourseCatalog and CourseCatalogTest also require updates.

Add an enrollmentCap parameter after the instructorId parameter and update the call to the Course constructor in CourseCatalog.
Update getCourseCatalog() to return a 5th column with the number of remaining seats. If you already delegate to Course.getShortDisplayArray(), no change will be needed unless you hardcoded the columns in the array to 4. If you do not delegate to Course.getShortDisplayArray(), you should do so!

CourseCatalogTest should change all calls to the Course constructor to add an enrollment cap. Update your tests accordingly. You may need to change your expected results file:

expected_course_catalog.txt

Fix Other Compiler Errors

Change the CourseCatalogPanel GUI file to remove any additional compiler errors related to the Course and enrollmentCap functionality.

CourseCatalogPanel Code

Update any additional tests, like RegistrationManagerTest, that need the enrollment capacity.

Make sure that all code is compiling and all tests are passing before moving on.
