Thread: 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")) 
    {
      startPlaying();
    }
    if (command.equals("1")) 
    {

Post the full text of the error message

This is the error message that I am getting


1 error found:
File: /Users/brad/Desktop/TicTacEvent.java [line: 5]
Error: /Users/brad/Desktop/TicTacEvent.java:5: TicTacEvent is not abstract and does not override abstract method itemStateChanged(java.awt.event.ItemEvent) in java.awt.event.ItemListener

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.
