Need help with bolded TODO methods in class CS2420Student in Java. 

NOTES:

The CS2420Student class must adhere to the following rules:

The equals method inherited from UofUStudent may not be overridden.

The addScore method adds one score for the student, in the given category. If category is not exactly one of four strings: "assignment", "test", "lab", or "quiz", then the method has no effect.

The addScore method must make good use of a switch statement.

For the purposes of this assignment, all scores (including labs and quizzes) are out of 100.

The computeFinalScore method must use the weighting of score categories given: assignments 40%, tests 40%, labs 10%, Canvas quizzes 10%, with the modification that if a student has below a 65% test average, their test average is their final course score. If the student does not have at least one score in each of the categories (assignment, test, lab, quiz), this method returns 0.0.

The computeFinalGrade method must use the mapping of numeric scores to letter grades given. If the student does not have at least one score in each of the categories, this method returns "N/A".

Private helper methods may be added, as needed, but no public methods may be added, other than those listed above. (Note that this is a general rule for CS 2420 assignments students are always permitted to add private methods to classes, but are restricted from adding public or protected methods.)
