title: How to change the first row and column in a 2D array
body: <p>Hello I'm fairly new to java and am creating a game that involves a 2D array. I'm trying to have a line at the top and side of the grid to display 0-10 and A-J which will be coordinates of the grid. I've made a simple 2D array: </p>
  
  <pre><code>String[][] board = new String [10][10];
  
      for (int row = 0; row&lt;board.length;row++) {
          for (int column = 0; column&lt;board.length; column++) {
              board[row][column] = ".";
              System.out.print(board[row][column] + "  ");
          }
          System.out.println();
      }
  </code></pre>
  
  <p>I've done some trial and error but I can't seem to find a solution and there's not much on this I can find on google. Any advice will be appreciated</p>
