You could use A List model based on Sorted collections to store your elements. These collections are based on the java.lang.Comparable interface.

Examples of its use can be seen on the java tutorial, starting on page:

http://java.sun.com/docs/books/tutorial/collections/interfaces/order.html

This example from the tutorial uses a class "Name" implementing "Comparable"

import java.util.*;

        class NameSort {
            public static void main(String args[]) {
                Name n[] = {
                    new Name("John", "Lennon"),
                    new Name("Karl", "Marx"),
                    new Name("Groucho", "Marx"),
                    new Name("Oscar", "Grouch")
                };
                List l = Arrays.asList(n);
                Collections.sort(l);
                System.out.println(l);
            }
        }

    If you run this program, here's what it prints:

        [Oscar Grouch, John Lennon, Groucho Marx, Karl Marx]
