I was thinking the same: wonderfully, unnecessarily large, but, that's how I used to code when I first started out. Make friends with arrays. Your exact program - the logic and all - could be condensed into at least 1/4 that size by working with arrays and more generalized methods, I'm sure. For example, you could have a method, setAllEnabled(boolean state) that looks like this:

java Syntax (Toggle Plain Text) 
  1. JButton[] gameBoard = new JButton[9];
  2.  
  3. .....
  4.  
  5. void setAllEnabled(boolean state) {
  6.     for(JButton jb : gameBoard)
  7.         jb.setEnabled(state);
  8. }

and that would do it. That one examlpe would save you a lot of room. Think of more examples!

fill it with x and o and whoever got 3 in a row wins.

10x simpler than the program.

the program for tic tac toe game is too large actually what it was needed could have been done in simpler and smaller in its size.

Sorry guys, but this is a terrible example of programming. We have endles code repeated 9 times because the author dosn't know about arrays. We have if/then/else/else... constructs running on for hundreds and hundreds of lines. We have nearly 1800 lines of code with just one single comment. We have two public Checker methods (nb capitalisation) guaranteed to create maxiimum confusion.
This would be unacceptable in any language.
