Help with Java Arrays and methods ASAP Please!!!

[gypsyman58]

First I need to create 2 classes. The first will contain an ID number and an array of 5 course titles. I also have to create a get and a set method for populating the ID. I also must create a method to get a course. It does this by taking an integer and returning the course to that position (0 through 4). Then I must create a set method that sets the value of one of the courses by taking two arguements a name and an integer and returning the name to the position indicated by the integer.

After that I must write an application that prompts the user for grades for 5 different courses: it will prompt for the the id number, then course data for each of 5 courses for that ID number. The user will enter the ID number of the student, then when prompted a number from 1 to 5 indicating which course, and a letter grade for the course.

So far this is what I have:

// CollegeCourse.java
// Chapter 8, Exercise 5a
// A CollegeCourse has an ID, credits, and a letter grade
 
public class CollegeCourse
{
    private String courseID;
    private int credits; 
    private char grade;
    public String getID()
    {
        return courseID;
    }
    public int getCredits()
    {
        return credits;
    }
    public char getGrade()
    {
        return grade;
    }
    public void setID(String idNum)
    {
 
    }
}
 
 

// Student.java
// Chapter 8, Exercise 5c
// A Student has an ID, and five CoollegeCourses,
 
public class Student
{
    private int stuID;
    private CollegeCourse[] course = new CollegeCourse[5]; 
 
    public int getID()
    {
        return stuID;
    }

    }
}
 

// InputGrades.java
// Chapter 8, Exercise 5b
// Allows input of 5 grades each for 10 students
 
import javax.swing.*;
public class InputGrades
{
    public static void main(String[] args)
    {
// http://www.brpreiss.com/books/opus5/html/page89.html
        Student[] students = new Student[10]; 
 
        int x, y, z;
        String courseEntry, entry = "", message;
        int idEntry, credits;
        char gradeEntry = ' ';
        boolean isGoodGrade = false;
        char[] grades = {'A', 'B', 'C', 'D', 'F'};
        for(x = 0; x < students.length; ++x)
        {
            Student stu = new Student();
            entry = JOptionPane.showInputDialog(null, "For student #" + (x + 1) + ", enter the student ID");
            idEntry = Integer.parseInt(entry);
            stu.setID(idEntry);
*********stuck here****************
            CollegeCourse temp = new CollegeCourse();
            temp.setID(courseEntry);
            temp.setCredits(credits);
            temp.setGrade(gradeEntry);
            stu.setCourse(temp, y);
        }
        students[x] = stu;
    }
        for(x = 0; x < students.length; ++x)
        {
            message = "Student #" + (x + 1) + " ID #" + students[x].getID();
            for(y = 0; y < 5; ++y)
            {
                CollegeCourse temp = new CollegeCourse();
                temp = students[x].getCourse(y);
                message = message + "\n" + temp.getID() + " " + temp.getCredits() + " credits. Grade is " + temp.getGrade(); 
                JOptionPane.showMessageDialog(null,message);
            }
            System.exit(0);
        }
    }
}
