The class structure for a Person domain can be viewed as follows Suppose that we are required to model students and teachers in our application. We can define a superclass called Person to store common properties such as and and subclasses Teacher for their specific properties. - For students, we need to maintain the courses taken and their respective grades; add a course with grade, print all courses taken and the average grade. Assume that a student takes no more than 30 courses for the entire program. - For teachers, we need to maintain the courses taught currently, and able to add or remove a course taught. Assume that a teacher teaches not more than 6 courses concurrently. Write the superclass and its subclasses and You also need to include a client class to test your code.
