Die Bubblesort

OK so I have to make this program where it takes input (names) from the user. The names are strings of course. The names are entered into an array where a bubblesort method dealy then sorts them alphabetically. I have it so that It will takes names from the user and puts them in an array but I have not the slightest clue on how to sort them. I have some sort of pseudo code kind of deal going on at the bottom.
import java.util.Scanner;

Code:

---

public class NameList
{

    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        int listLength, index = 0;
        String[] nameList;
        String nameIndex;

        System.out.print("How many names? ");
        listLength = scan.nextInt() + 1;
        nameList = new String[listLength];

        while (index < listLength)
        {
            nameIndex = scan.nextLine();
            nameList[index] = nameIndex;

            System.out.print("=> ");
            index++;
        }

        for (int k = nameList.length - 2; k > 1; k--)
        {
            for (int j = k; nameList[j] < nameList[j + 1]; j++)
            {
                swap(nameList[j], nameList[j + 1]);
            }
        }
    }
}

You can't use < for comparing strings. Use the compareTo method.
Then you obviously also need to implement that swap method (that should be simple enough).
Also make sure to understand the algorithm.

Thanks but I ended up just using

Arrays.sort(nameList);

Does the same thing. Screw bubblesort;
