Do not allow the ID to be changed after an object has been constructed. Provide a method in the ProfessorRating class to compute and return the overall ratinmg avaerage. Print all ratings and the average rating formatted with not digits to the right of the decimal from the implementation class. Use a single class method to enter all data.
