Language is Java. Need subclasses of the superclass Course called MusicCourse and ComputerScienceCourse and then a class that uses both to provide the output shown. NO ABSTRACT CLASS NEEDED.

Write a program that will prompt the user for information about a schedule of courses at a university and then print out the course schedule. Do not make any assumptions about the number of courses the user will enter. There are two types of courses in the schedule: Music (MUS) courses and Computer Science (COM) courses. You program will need to ask for different information from the user depending on the type of course. After the user has entered all the course information, your program should print out the schedule. You do not have to worry about courses that overlap in time, duplicate courses, or other scheduling problems that may arise.

Both Music and Computer Science courses have a subject, a course number, and a meeting time. In addition, Computer Science courses have a lab time associated with them. Music courses have a private lesson room and a private lesson instructor associated with them.

To hold course information, you program should define subclasses of the superclass Course called MusicCourse and ComputerScienceCourse. Course meeting times and lab times in the program are stored in objects of type MeetingTime. Times will be stored using the 24-hour clock, with the fraction 0.5 representing the one-half hour time. The source for both the Course and MeetingTime classes are attached.

In addition to other methods, both the MusicCourse and ComputerScienceCourse classes must have a method called toString() that returns a neatly formatted String representation of the object when called. You must use this method to print out the course onformation. MusicCourse.toString() and ComputerScienceCourse.toString()should call the toString() methods of the Course and MeetingTime classes to do their work. Do not duplicate the functionality of Course.toString() and MeetingTime.toString(). Do not make any changes or additions to either the Course class or the MeetingTime class; you must use them exactly as they are given.
