2. Consider the course enrollment system. Four classes are used. The student enrollment (methods: getName. GetDate,prepareInvoice,postPayment) ,the course, the account receivable, the enrollment report generator. The account receivable and the enrollment report generator are derived classes from student enrollment class. Please give the class diagram of the system and see if there is any problem in the operation of the classes. If there is provide the appropriate class diagram.
