Guys this how can i place an O automatically in a position that a omputer will generate?

Please edit your post and wrap your code with code tags:
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.

What have you tried? Which part of this is giving you trouble? Break your problem down into smaller steps, focus on a single step (with an SSCCE), and we'll go from there.

Like we said, code you post should use the highlight tags. And it should also be in the form of an SSCCE. Posting a snippet is too little, posting your entire project is too much.

I see some problems in the code:
1) The copy and paste of statements were not fixed:

      else
         	if(input.equals("X"))
       	{
             button3.setText("X");
             button3.setEnabled(false);
        }
         else
         	if(input.equals("X"))
       	{
             button4.setText("X");
             button4.setEnabled(false);
        }
         else
         	if(input.equals("X"))

The too many repeated tests for equal to X

2)The nested code is not properly indented making the code hard to read:

       while(count == 2 || count == 4 || count == 6 || count == 8 || count == 10)
 
        	{
//*******>>>> FOLLOWING CODE SHOULD BE INDENTED <<<<<<<<<<<<<<<<<<<***
            String input = JOptionPane.showInputDialog("welcome  you will take X and computer wiil take O \n Please ENTER number you want to play ");
        int pawn = Integer.parseInt(input);
        if ( input.equals("1"))
        {
        	button1.setText("X");
            button1.setEnabled(false);
            //letter = "X";

Try debugging the code by adding several println() statements that print out messages when methods are executed and also print out the values of variables as they are used and changed.
For example print out a message at the start of each method.
Print out the value of the count variable as it is changed and every where its value is tested.
The printout will show you what the program is doing and help you understand why the program executes like it does.

Did you read post#6? The new code has the same problems:

  else
         	if(input.equals("X"))
       	{

Have you tried debugging the program to see what it is doing when it executes? See post#6.

it says...
Create a Tic Tac Toe game. In this game, two players alternate placing Xs and Os
into a grid until one player has three matching symbols in a row, either horizontally,
vertically, or diagonally. Create a game in which the user is presented with a threeby-
three grid containing the digits 1 through 9. When the user chooses a position by
typing a number, place an X in the appropriate spot. Generate a random number for
the position where the computer will place an O. Do not allow the player or the
computer to place a symbol where one has already been placed. Figure 9-26 shows
the first four windows in a typical game. When either the player or computer has
three symbols in a row, declare a winner; if all positions have been exhausted and no
one has three symbols in a row, declare a tie. Save the game as TicTacToe.java.
You are required to develop this game using NETBEANS as the interface.

That's not how this works. We aren't going to do your homework for you.

We've asked you to do several things, many of which you seem to be ignoring. How can we help you if you just ignore our advice?

Please see the link in my signature on asking questions the smart way, then we'll go from there.
