Tic Tac Toe is very simple game. It need only very simple AI to develop. So I'm giving you very simple Java code which the CPU player can find the empty cell and play there. There is no other skills on CPU player.
The only characteristics of CPU player is to find the empty cells and select a cell in random to play there.
