我是一个初学者，正在创建一个程序，将8个皇后放在棋盘上。
我必须：

1）创建一个空白棋盘（8X8 2D整数数组，全为0）
2）使用循环，要求用户在板上放置8个位置，在该位置将0替换为1
3）显示最终板

我不必进行任何错误检查或检查重复的位置。

我的代码无法正确存储值。
只有最后一个可以正确打印。

        int columnValue = Integer.parseInt(JOptionPane.showInputDialog("Enter the column value (1-8)"));
        int rowValueFinal = rowValue - 1;
        int columnValueFinal = columnValue - 1;

最佳答案

该循环不需要存在。

您正在清理整个电路板并仅设置一个单元格

for (int i = 0; i < 8; i++) {
    for (int j = 0; j < 8; j++) {
        if (i == rowValueFinal && j == columnValueFinal) {
            chessBoardArray[i][j] = 1;
        } else {
            chessBoardArray[i][j] = 0;
        }
    }
}

您应该将整个循环替换为

chessBoardArray[rowValue - 1][columnValue - 1] = 1;
