Best way to sort data from a file alphabetically

Question

If I have a file as such:
FIRST_NAME|LAST_NAME
I want to display the data in alphabetical order by last name and by first name. what is the best way to do this? I found java.util.Arrays
but i thought that it might be best if i read the data into a linked list. I want to display it on a form, so that I can press a next and previous button. Next will show the next record in alphabetical order after the previous one(B->C) and previous would go (C->B)
thanks.

Answer 1

How about this:
Create a PersonRecord object, and have it implement Comparable.
import java.util.Comparator;
public class PersonRecord implements Comparable < PersonRecord >
    public static Comparator < PersonRecord > surnameComparator ()
        public int compare (PersonRecord pr1, PersonRecord pr2)
            return pr1.getSurname ().compareTo (pr2.getSurname ());
    public static Comparator < PersonRecord > nameComparator ()
        public int compare (PersonRecord pr1, PersonRecord pr2)
            return pr1.getName ().compareTo (pr2.getName ());
}See java.util.Comparator, java.lang.Comparable.
Then use Arrays.sort(List, Comparable) at your own discretion...
I've said enough; work that part out yourself.
