Question

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 (0 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 (0 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 professor enters only A, B, C, D, or F for the grade value for each course.

Answer 1

The implementation involves creating a CollegeCourse class with methods to manipulate course-related details and a Student class to manage student information and their courses. An application for grade entry should ensure that only valid letter grades can be entered.

Step-by-step explanation:

The question is asking for the implementation of the CollegeCourse and Student classes, along with the methods and fields associated with them. The CollegeCourse class should have fields for course ID, credit hours, and letter grade, as well as get and set methods for each field. The Student class should contain an ID number and an array of five CollegeCourse objects, along with get and set methods for the ID number and a get method for a specific CollegeCourse. It should also have a set method to change the value of a CollegeCourse object.

To implement the CollegeCourse class, you will need to define fields for the course ID, credit hours, and a letter grade. Methods to get and set these fields should be included. The Student class will contain an ID number and an array of five CollegeCourse objects, with methods to get and set the ID number and get and set methods for the CollegeCourse objects based on their position in the array.When developing an application for a professor to enter grades for different courses, it's important to include prompts and verification processes to ensure the only acceptable grades are A, B, C, D, or F.
