    Default Tic Tac Toe Program

    Alright, so I have run into a bit of an error and I am not sure where I have gone wrong. I have two sets of code that should work together. The problem seems to be in the second file TicTacEvent on line 5. I read something about associating the file, but I do not fully understand what the means or how I am supposed to go about doing that.

      void b2()
      {
        clicks = clicks + 1;
        if ((clicks%2)==1)
        {
          gui.boxes[0][1].setIcon(a);
          check[0][1] = 1; 
        }
        else
        {
          gui.boxes[0][1].setIcon(b);
          check[0][1] = 2;
        }
      }

    import javax.swing.*;
    import java.awt.event.*;
    import java.awt.*;
     
    public class TicTacEvent implements ItemListener, ActionListener, Runnable
    {
      TicTac gui;
      Thread playing;
      ImageIcon a = new ImageIcon("x.jpg");
      ImageIcon b = new ImageIcon("o.jpg");
      int clicks = 0;
      int win = 0;
      int[][] check = new int[3][3];
     
      public TicTacEvent (TicTac in)
      {
        gui = in;
        for (int row=0; row<=2; row++)
        {
          for (int col=0; col<=2; col++)
          {
            check[row][col]=0;
          }
        }
      }
     
      public void actionPerformed (ActionEvent event)
      {
        String command = event.getActionCommand();
     
        if (command.equals("Play"))

    method itemStateChanged(java.awt.event.ItemEvent)
    The compiler is telling you to define that method in your class because you promised to do that when you coded: implements ItemListener
    If you don't understand my answer, don't ignore it, ask a question.

    Ok, so I have been trying to get my head around this but I am clearly missing something basic. I have to be honest and just say that I just do not understand what I need to do. The standard approach to define a method would be something like public void ItemListener(), but does not seem to make sense and if it did I would have no clue where to put it. Then there is declaring an abstract class which seems to make more sense but again, I am confused by how to use it.

    I apologize as this is the most advanced thing that I have ever done and I am try to learn by putting different pieces of information together.

    implements ItemListener, ActionListener, Runnable
    The class implements several interfaces. See what it did for the ActionListener interface and the Runnable interface and do the same kind of thing for the ItemListener interface's required method.
