写一个八皇后小游戏的Java代码

当然可以，下面是八皇后小游戏的Java代码：

public class EightQueens {
    private int row = 8;
    private int[] result = new int[row];
    private int count = 0;

    public void getEightQueens() {
        check(0);
        System.out.println("共有" + count + "种解法！");
    }

    private void check(int n) {
        if (n == row) {
            printQueens();
            count++;
            return;
        }
        for (int i = 0; i < row; i++) {
            result[n] = i;
            if (judge(n)) {
                check(n + 1);
            }
        }
    }

    private boolean judge(int n) {
        for (int i = 0; i < n; i++) {
            if (result[i] == result[n] || Math.abs(n - i) == Math.abs(result[n] - result[i])) {
                return false;
            }
        }
        return true;
    }

    private void printQueens() {
        for (int i = 0; i < row; i++) {
            for (int j = 0; j < row; j++) {
                if (result[i] == j) {
                    System.out.print("Q ");
                } else {
                    System.out.print("* ");
                }
            }
            System.out.println();
        }
        System.out.println();
    }

    public static void main(String[] args) {
        EightQueens eightQueens = new EightQueens();
        eightQueens.getEightQueens();
    }
}

有什么问题需要我帮您解答么？
