Explanation of Solution

Program:

File name: “CollegeCourse.java”

//Define a class named CollegeCourse

public class CollegeCourse

{

    //Declare the private variables

    private String courseID;

    private int credits;

    private char grade;

    //Define a get method that returns the course ID

    public String getID()

    {

        //Return the value

        return courseID;

    }

    //Define a get method that returns the credit hours

    public int getCredits()

    {

        //Return the value

        return credits;

    }

    //Define a get method that returns the letter grade

    public char getGrade()

    {

        //Return the value

        return grade;

    }

    //Define a set method that takes the course ID

    public void setID(String idNum)

    {

        //Assign the value

        courseID = idNum;

    }

    //Define a set method that takes the credit hours
