a) Write a method in the Department class called offerCourse (Course course) that adds the given course to the department. b) Write a method in the Department class called print CoursesOffered () that displays the list of all courses offered by the department in arbitrary order. It should show all course information (Hint: call the course's tostring() method); c) Write a method in the Student class called registerFor (Course course) that registers a student in the given course. If the student is already registered in the course, then the method does nothing. Otherwise, the appropriate student, Course, and Department objects are updated as necessary. d) Write a method in the Department class called printStudentsByName() that displays a list of all students taking courses in this department. This method should show all student information (Hint: use the Student's toString()). e) Write a method in the Student class called isRegisteredInCourse (Course course) that returns a Boolean value indicating whether or not the given student is registered for any course in this department. f) Write a method in the Department class called isstudent Registered (Student student) that returns the boolean value indicating whether or not the given student is registered for any course in this department.
