Android sort array

how can i sort this array by date or name?

String[][] datetable= new String[21][2];

datetable[0][0] = "2011.01.01";
datetable[0][1] = "Name1";
datetable[1][0] = "2011.01.03";
datetable[1][1] = "Name2";
.
.
.
datetable[20开发者_JAVA百科][0] = "2011.02.16";
datetable[20][1] = "Name3";

I would do what the poster linked to, only I wouldn't use final so much.

Arrays.sort(datetable, new Comparator<String[]>() {
    @Override
    public int compare(String[] entry1, String[] entry2) {
        // Sort by date
        return entry1[0].compareTo(entry2[0]);
    }
});
