This relates to a previous question ( .. i forgot to get an answer before i closed it :( ) 

How do i search for a string in a 2 dim string array (column 0)

I have the following 2 dim string table. It is sorted by its first column.

I then thought i could use a Array.binarySearch (works fine for a one dimensional array) but i can't get my head around on how to do it on a 2 dim.

I need some expert advice.

import java.util.Arrays;
import java.util.Comparator;

public class TwoDimStringTable {
    public static void main(String [] args) {
        int i = 0;
        String[][] sTabell = new String[8][2];
        sTabell[0][0] =  "Ola";                sTabell[0][1] =  "Ola";
        sTabell[1][0] =  "var";                sTabell[1][1] =  "kunne";
        sTabell[2][0] =  "fra";                sTabell[2][1] =  "engelsk";
        sTabell[3][0]=   "Sandefjord";         sTabell[3][1]=   "ei";
        sTabell[4][0] =  "Han";                sTabell[4][1] =  "men";
        sTabell[5][0] =  "var";                sTabell[5][1] =  "han";
        sTabell[6][0] =  "lettmatros";         sTabell[6][1] =  "klarte";
        sTabell[7][0] =  "ombord!";            sTabell[7][1] =  "seg";

        for ( i = 0; i <= sTabell.length-1; i++) {
            System.out.println(sTabell[i][0] + "  " + sTabell[i][1]);
        for (i = 0; i < sTabell.length; i++) {
        Arrays.sort(sTabell, new Comparator<String[]>() {
            public int compare(String[] r1, String[] r2) {
                return, r2);
        for ( i = 0; i <= sTabell.length-1; i++) {
            System.out.println("i = " + i + " " + sTabell[i][0] + "  " + sTabell[i][1]);
