ゲーム TicTacToe を実行するプログラムを作成しようとしています。すべてのメソッドの作成が完了し、あとはドライバー プログラムを作成するだけです。ドライバプログラムを作成する前に、ボードを文字と一緒に印刷しようとしましたが、私の方法は正しくないと思います。私のエラーは次のようになります。
java.lang.ArrayIndexOutOfBoundsException: 3

ここに私の2つのプログラムがあります：
これは私のドライバー プログラムですが、まだ完成していないようです。最後に表示されるのはテンプレートです。これにより、各プログラムがどのように機能するかがわかります。
class TicTacToe
{
public static void main(String [] args)
{
//System.out.println("Welcome! Tic-Tac-Toe is a two player game.");
//System.out.println("Enter player one's name: ");
TicTacToeBoard game = new TicTacToeBoard();
System.out.println(game.toString());
//int count = 0;
game.move('x', 1, 3);
// game.move('o', 1, 1);
/* while (game.gameWon() !true || count != 9)
{
System.out.print(game.move());
System.out.print(game.isEmpty());
}*/
}
}
これがすべてのメソッドの場所です......
