混合然后打印阵列，但它们最终都是相同的吗？

标签： java arrays

我正在进行数独游戏。我有一个数组（puzzle [] [] []）包含九个其他数组（zone1 [] [] - zone9 [] []），每个数组最初包含{{1,2,3}，{4,5,6 }，{7,8,9}}（并且他们已经从zone1.clone（）中分配了这些值，因此它不是引用问题。）

我将这些值与：

混合 
Random rand = new Random();
for(int z = 0; z < 9; z++) //cycles through zones
{
    for(int i = 0; i < 3; i++) //cycles through zone rows
    {
        for(int j = 0; j < 3; j++) //cycles through zone columns
        {
            int temp = puzzle[z][i][j];
            int newI = rand.nextInt(3);
            int newJ = rand.nextInt(3);
            puzzle[z][i][j] = puzzle[z][newI][newJ];
            puzzle[z][newI][newJ] = temp;
        }
    }
}

然后我通过将所有值添加到char数组（添加边框）将拼图打印到屏幕上。那里不应该有任何问题，因为我只是分别通过拼图[8] [2] [2]添加拼图[0] [0] [0]。

因此，当我运行该程序时，我希望得到9个＆＃34;区域＆＃34;具有不同的混合值。相反，我得到了这个：

/-----------------------\
| 2 1 5 | 2 1 5 | 2 1 5 |
| 6 9 8 | 6 9 8 | 6 9 8 |
| 4 3 7 | 4 3 7 | 4 3 7 |
|-------+-------+-------|
| 2 1 5 | 2 1 5 | 2 1 5 |
| 6 9 8 | 6 9 8 | 6 9 8 |
| 4 3 7 | 4 3 7 | 4 3 7 |
|-------+-------+-------|
| 2 1 5 | 2 1 5 | 2 1 5 |
| 6 9 8 | 6 9 8 | 6 9 8 |
| 4 3 7 | 4 3 7 | 4 3 7 |
\-----------------------/

我确定它很简单，但我只是没有看到它。

编辑：好的，这是打印部分。

输出如下：

因此，您的代码片段可以完成他们的工作（尽管生成的电路板对于Sudoku无效）。 问题出在其他地方。

此解决方案只需one random value和one loop即可启动益智游戏。

    for(byte r = zero, c; nine > r; r ++) {
        if(three == r || six == r) {
            rand = maze[r - three][zero];
            rand = nine == rand ? one : (byte)(rand + one);
        } else {
            rand = zero < r ? maze[r - one][six] : rand;
        }
        for(c = zero; nine > c; c ++) {
            maze[r][c] = rand;
            rand = nine == rand ? one : (byte)(rand + one);
        }
    }
