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);
		}
	}
}
