当我运行我的程序时，没有任何显示

Question

我只是Java oop的初学者，我真的需要帮助，我想做一个Tic-Tac-Toe游戏。 没有错误，但它没有向我显示任何内容。 控制台工作正常，因为我尝试了别的东西，但我真的不知道问题出在哪里。 对不起，如果我在英语中有任何错误，那我的母语不是。

谢谢。

        //char c;
        int i = 0;
        int[] tab;

        //test = grille.checkBoard();
        System.out.println(test);
        player.choixSigne();
        //c = player.getSigne();
        while ((test == false) && (i < 9)) {
