九宫格游戏的 JAVA 实现

二维数组实现九宫格小游戏，还未添加输赢判断逻辑，后面补充

public void twoDimList(){
        Scanner scanner = new Scanner(System.in);
        String[][] qipan = {
  {"[]","[]","[]"},{"[]","[]","[]"},{"[]","[]","[]"}};
        int i = 1;
        while(i > 0){
            if(i % 2 == 1){
                System.out.println("请蓝方落子");
                System.out.println("请输入X轴坐标");
                int x = scanner.nextInt();
                System.out.println("请输入Y轴坐标");
                int y = scanner.nextInt();
                if(x >= 1 && y >= 1 && x <= qipan[0].length && y <= qipan.length) {
                    if(qipan[qipan.length-y][x-1].equals("[]")) {
                        qipan[qipan.length-y][x-1] = "X";
                    }
                    else {
