Program Dasar Game Tic Tac Toe dengan Java AWT

Gloddaggghhhh..!!!
Jadi juga bikin program game tic tac toe yang dinamai TikTakTuk menggunakan bahasa Java, pakai AWT aja ah (yang Swing ntar aja [tapi ga janji] :p).

Sesuai judul, ini hanya program dasar... bukan program final... tujuannya untuk mempelajari algoritmanya dan even driven pada Java GUI doang... nothing less nothing more. Dan program dimainkan oleh dua orang.

Yang tidak ada di program ini :

• new game
• skor
• pop up message (message box gitu loh)
• milih X atau O
• artificial intelligence / kecerdasan buatan (manusia vs komputer)
• status bar
• menu bar
• bayaran utk penulis :p~~~
  

Ini dia source code-nya :
