I'm taking an intro to Java course and currently we're taking about arrays. I have the two java files below that I need for the assignment to work, but I'm not sure what to do next with my code.

Here's what the assignment says to do:

Create a 'CollegeCourse class. The class contains fields for the course ID (for example, "History"), credit hours (for example, 3) and a letter grade (for example, 'A'). Include get() and set() accessor methods for each field.

Create a 'Student' class containing an ID number and an array of five CollegeCourse objects. Create a get() and set() method for the Student ID number.
Also, create a get() method that returns one of the student's CollegeCourses; the method would take an integer argument and return the CollegeCourse in the position(0 through 4).
Next, create a set() method that sets the value of one of the student's CollegeCourses; the method would take two arguments -- a CollegeCourse and an integer representing the CollegeCourse's position (o through 4).

-----------------------
//CollegeCourse.java file below:

class CollegeCourse
{
private String courseID;
private int creditHours;
private char letterGrade;

public CollegeCourse(String course, int credits, char grades)
{
courseID = course;
creditHours = credits;
letterGrade = grades;
}

//Set Functions

public void setcourseID(String name)
{
courseID = name;
}
public void setcreditHours(int num)
{
creditHours = num;
}
public void setletterGrade(char letter)
{
letterGrade = letter;
}

//Get Functions

public String getCourseID()
{
return courseID;
}
public int getCreditHours()
{
return creditHours;
}
public char getLetterGrades()
{
return letterGrade;
}
}

==========================
public class Student
{
public static void main(String[] args)
{
showValues(courses[0]);
}

public Student(int ID)
{
idNumber = ID;
courses[0] = new CollegeCourse ("History", 0, 'A');
courses[1] = new CollegeCourse ("Math", 0, 'A');
courses[2] = new CollegeCourse ("English", 0, 'A');
courses[3] = new CollegeCourse ("Music", 0, 'A');
courses[4] = new CollegeCourse ("Science", 0, 'A');
}

public int getCourse()
{
return idNumber;
}
public static void showValues(Show c)
{
System.out.println c.getCourse();
}
}


Thanks
