Tic tac Toe Getting the Images to work for the buttons

[angelus2402004]

Hi. I've been working on this too long, and I can't figure out how to get this area fixed under Who's Turn it Is. I keep getting errors. The teacher said that I need to "Create an Icon variable to store the X or the O Icon that you already instantiated in the constructor"- But everything I try doesn't work. Thank You.

 public Java_game() //this is a constructor
   {
       setLayout(new GridLayout(4,3));//a 4 by 3 grid
        Icon X = new ImageIcon(getClass().getResource("X.gif"));
        Icon O = new ImageIcon(getClass().getResource("O.gif"));

  //private inner class for event handling of buttons
                         private class MessageListener implements ActionListener{

                             public void actionPerformed(ActionEvent event)
                             {
                                  count++;

                                         //Who's Turn It is
                                         if (count == 1 || count == 3 || count == 5 || count == 7 || count == 9)
                                         {

                                Icon = ("X.gif");

                                         }
                                         else if (count == 2 || count == 4 || count == 6 || count == 8 || count == 10)
                                         {

                                      Icon = ("O.gif");




        }
                                 if(event.getSource() == button0)
                                 {
                                 button0.setIcon();
                                 button0.setText(null);
                                 button0.setEnabled(false);

Can you explain what your problem is?
If you need to figure out how to put an image in a button, write an very small program that reads an image and shows it in a button. Nothing more.

Post the test program if you need help with it.

This is confusing coding:
button0.setIcon(Icon);

using a variable name with uppercase first letter that looks like the name of a class or interface.
You should use a variable name there.
