Refer to the UML diagram above and implement the Course class. After you define the Course class, you must create a Course object with the following details:
Programming I, WXES1114, taught by SMT.
Besides, your program must test all the accessor and mutator methods you had defined and the toString() method. toString() method is a special method inherited from the Object class. You have to override this method to display all the information about a course.
