title: "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 2
body: <p>I am trying to create a Tic-Tac-Toe game in Java for one of my classes. The program takes an int from the command line and creates a JButton 2D array of that size. It also has an undo and a new game button. The program compiles and runs and when I click the new game button no exception occurs, but when I click on one of the game spaces, it throws this exception. </p>

  </code></pre>
  
  <p>My newMove method simply takes the x and y locations of the button and the turn (1 or 2), and adds it to the 2D int array associated with the GameTester class. </p>
  
  <pre><code>public void newMove(int x, int y, int turn)
      {
      board[x][y] = turn;
  }
  </code></pre>
  
  <p>This is part of the loop within my ActionListener that includes where the newMove method is called.</p>
  
  <pre><code> if (event == buttons[x][y])
  {
      theBoard.moveLog(x,y);
      theBoard.newMove(x,y,toggle);
      if (toggle == 1)
      {
          buttons[x][y].setText("X");
          toggle = 2;
      }
      else
      {
          buttons[x][y].setText("O");
          toggle = 1;
      }
              ..... 
      }
  </code></pre>
  
  <p>Any help is greatly appreciated! :)                     </p>
