Linked List implementation of various classes

[the_rider9]

I am relatively new to Java, and I am currently in a dead end on a program with no idea how to continue. Here is where I am at.

I implemented a typical singly linked list which contains multiple nodes of class "Student" (1 node per student). However, I need every student to be able to implement a class called "Courses" any amount of time. For example, 1 student in the linked list might have 4 courses (math, bio, phys,english) whereas another student in the linked list might have 23.

What data structure would be optimal for accessing different courses from different students? How would I tie both classes together in such a fashion?

Thanks in advance!

What kind of "container" you put the items in would depend on how you want to access them.
Serially from the beginning: ArrayList
Randomly by name: Map

I agree with Norm, data structure will depend on how you will access "Courses". I think ArrayList is a better choice, but this is my personal opinion. Regarding your second question i think you can use something similar to that:

import java.util.*;
public class Student {
	Student(String aName,String... args)
	{
		name=aName;
		cname=args;
		for(int i=0;i<cname.length;i++)
		{
			cour.add(new Courses(cname[i]));
		}
	}
	public void showAll()
	{
		for(int i=0;i<cname.length;i++)
		{
			System.out.println(cour.get(i).showCourses());
		}
	} 
	 private String name;
	 private String[] cname;
	 private ArrayList<Courses> cour = new ArrayList<Courses>();
}

Class "Courses" here has only one method "showCourse()" that returns name of the course.
