Sort a two dimensional array based on one column

I have the data:

"Something1" "TRUE"
"Something2" "FALSE"
"Something3" "FALSE"
"Something4" "TRUE"

That I then store in a multidimensional array:

String[][] myData = new String[data.length][2];

Now I want to sort this array so that it is ordered by “TRUE” first, so it becomes:

"Something1" "TRUE"
"Something4" "TRUE"
"Something2" "FALSE"
"Something3" "FALSE"

I’m looking at Arrays.sort(); but not sure how to implemtent this or if this is even the best way.

Answer 1

Sort your array with a custom comparator:

Arrays.sort(myData , new Comparator<String[]>() {
            @Override
            public int compare(String[] o1, String[] o2) {
                return ((String) o2[1]).compareTo(o1[1]);
            }
        });
