A. Implement the CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Next, create the Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the student's ID number. Also create a get method that returns one of the student's CollegeCourses ; the method takes an integer argument and returns the CollegeCourse in that position (O through 4). Next, create a set method that sets the value of one of the Student's CollegeCourse objects; the method takes two arguments - a CollegeCourse and an integer representing the CollegeCourse's position (O through 4). B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course data for five courses. Use prompts containing the number of the student whose data is being entered and the course number-for example, Enter ID for student \#1, and Enter course ID \#5. Verify that the protessor enters only A, B, C, D, or F for the grade ogramming Exercise 8-7
