Question

I need help creating a Tic-Tac-Toe game programmed in JAVA. The game has to be a player vs computer (artificial intelligence) Tic-Tac-Toe. The board has to be 1D (one-dimension).

Requirements:

1. Computer (artificial intelligence) must be aggressive and take every opportunity to win the game, block the user from winning and if the human makes a mistake, then the computer will capitalize on it and win if possible

2. Don't use infinite loops: for(;;) while (true) nor use break statements to exit loops.

3. Not looking for a player vs player tic tac toe, it has to be a player vs computer tic tac toe.
