我想在Java中使用标志启动Minsweeper

Question

https://github.com/shonejin/Minesweeper/blob/master/src/com/shonejin/minesweeper/game/Board.java

我研究Minesweeper算法。我想开始游戏并附加标志。

我在第65行修改了以下代码，但未更改

    // randomly place mines in the board
    // and update "count of mines" of neighboring cells
    private void putMines() {
        Random rand = new Random();
        int mines = NMines;
        while (mines-- > 0) {
            int pos = rand.nextInt(NCovered);
            int x = pos % N;
            int y = pos / N;
            if (isMine[y][x])
                mines++;
            else {
                isMine[y][x] = true;
                for (int d = 0; d < di.length; d++) {
                    mineCnt[y + di[d] + 1][x + dj[d] + 1]++;
                    states[x][y] = CellStates.FLAGGED  // What I attached

                }
            }
        }
    }
