In starter code for CreatingCourses java, please complete one TODO in main and define three methods (see the starter code). The program does the following: (1) Prompt the user to enter a sequence of courses through a loop and save all the courses in an array list. (2) When user doesn't have more courses to enter, sort the courses by their category and then by CRN. You will need to implement the Comparable interface somewhere. (3) If the user didn't enter any course, the program should print "No courses entered." and exit. Otherwise, proceed as follows: a. Display all the courses. b. Prompt user to enter a course name, search through the array list (when comparing, ignore case difference). If found, display "Course found." And then display the course. If not found, display "Course not found." n No courses entered. Sample run 2: Do you have a course to enter (Y/N)? Enter CRN number: 1000 Enter course category: Math Enter course name: Pre Calc Is this a STEM course (true/false)? true Is this course an (online), an (in-person), or a (hybrid) course? online Do you have a course to enter (Y/N)? Y Enter CRN number: 1001 Enter course category: English Enter course name: Composition II Please enter course level (lower or upper): lower Is the English course a reading course (R), a writing course (W), or both (RW)? W Do you have a course to enter (Y/N)?
