Double Dimension Arrays Java

My code works perfectly fine though i don't know how to print the number of the row before the word "row". It should be Row 1, Row 2, and so on. Any clues on how to do it? And also a clue to store these strings in a simpler way. Thank youuu :)

System.out.println("\t A \t B \t C \t D \t E \t F");
String [][] TwoDim = new String[13][6];
TwoDim[0][0] = "*";
TwoDim[0][1] = "*";
TwoDim[0][2] = "X";
TwoDim[0][3] = "*";
TwoDim[0][4] = "X";
TwoDim[0][5] = "X";

TwoDim[1][0] = "*";
TwoDim[1][1] = "X";
TwoDim[1][2] = "*";
TwoDim[1][3] = "X";
TwoDim[1][4] = "*";
TwoDim[1][5] = "X";

TwoDim[2][0] = "*";
TwoDim[2][1] = "*";
TwoDim[2][2] = "X";
TwoDim[2][3] = "X";
TwoDim[2][4] = "*";
TwoDim[2][5] = "X";

TwoDim[3][0] = "X";
TwoDim[3][1] = "*";
TwoDim[3][2] = "X";
TwoDim[3][3] = "*";
TwoDim[3][4] = "X";
TwoDim[3][5] = "X";

TwoDim[4][0] = "*";
TwoDim[4][1] = "X";
TwoDim[4][2] = "*";
TwoDim[4][3] = "X";
TwoDim[4][4] = "*";
TwoDim[4][5] = "*";

TwoDim[5][0] = "*";
TwoDim[5][1] = "X";
TwoDim[5][2] = "*";
TwoDim[5][3] = "*";
TwoDim[5][4] = "*";
TwoDim[5][5] = "X";

TwoDim[6][0] = "X";
TwoDim[6][1] = "*";
TwoDim[6][2] = "*";
TwoDim[6][3] = "*";
TwoDim[6][4] = "X";
TwoDim[6][5] = "X";

TwoDim[7][0] = "*";
TwoDim[7][1] = "X";
TwoDim[7][2] = "*";
TwoDim[7][3] = "X";
TwoDim[7][4] = "X";
TwoDim[7][5] = "*";

TwoDim[8][0] = "X";
TwoDim[8][1] = "*";
TwoDim[8][2] = "X";
TwoDim[8][3] = "X";
TwoDim[8][4] = "*";
TwoDim[8][5] = "X";

TwoDim[9][0] = "*";
TwoDim[9][1] = "X";
TwoDim[9][2] = "*";
TwoDim[9][3] = "X";
TwoDim[9][4] = "X";
TwoDim[9][5] = "X";

TwoDim[10][0] = "*";
TwoDim[10][1] = "*";
TwoDim[10][2] = "X";
TwoDim[10][3] = "*";
TwoDim[10][4] = "X";
TwoDim[10][5] = "*";

TwoDim[11][0] = "*";
TwoDim[11][1] = "*";
TwoDim[11][2] = "X";
TwoDim[11][3] = "X";
TwoDim[11][4] = "*";
TwoDim[11][5] = "X";

TwoDim[12][0] = "*";
TwoDim[12][1] = "*";
TwoDim[12][2] = "*";
TwoDim[12][3] = "*";
TwoDim[12][4] = "X";
TwoDim[12][5] = "*";

for(int i = 0; i<13; i++){
    System.out.print("Row \t");
    for(int j = 0; j <6; j++){
        System.out.print(TwoDim[i][j] + "\t");
    }
    System.out.println();
}

Don't use the hardcoded value of row and column,Use below code:

    for(int i = 0; i<TwoDim.length; i++){   // Iterate to row count

        System.out.print("Row-"+(i+1)+"\t"); // Change i to i+1

            for(int j = 0; j <TwoDim[i].length; j++){  // Iterate the column count
                System.out.print(TwoDim[i][j] + "\t");
        }

        System.out.println();
    }

System.out.print("Row " + i +  "\t");

i is the first index in your array, and thus corresponds to the row. If you want to make is 1 based rather than a 0 based index, output i + 1 each time.

Well, iis your row number, starting from 0, so just write (assuming you want to start at 1):

for(int i = 0; i<13; i++){
    System.out.print("Row \t"+(i+1)+" ");
    for(int j = 0; j <6; j++){
        System.out.print(TwoDim[i][j] + "\t");
    }
    System.out.println();
}

Did you tried:

for(int i = 0; i<13; i++){
   System.out.print("Row \t " + i);
   for(int j =0; j < 6; j++ {
       ...
   }
}

Try this:

System.out.print("Row \t"+i);

In case your indexing starts from 1

 System.out.print("Row \t"+(i+1));

Change your line

System.out.print("Row \t");

to something like this:

System.out.print("Row " + (i + 1) + "\t");
