使用java代码,实现数独。需要根据输入的9X9盘面上的数字,推算出所有剩余空格的数字,并且满足每一行、每一列、每一个3X3粗线宫内的数字均含1-9,并且不重复。

以下是使用java代码实现数独的示例：

public class SudokuSolver {
    private int[][] board;

    public SudokuSolver(int[][] board) {
        this.board = board;
    }

    public boolean solve() {
        int row = -1, col = -1;
        boolean isEmpty = true;
        for (int i = 0; i < 9; i++) {
            for (int j = 0; j < 9; j++) {
                if (board[i][j] == 0) {
                    row = i;
                    col = j;
                    isEmpty = false;
                    break;
                }
            }
            if (!isEmpty) {
                break;
            }
        }
        if (isEmpty) {
            return true;
        }
        for (int num = 1; num <= 9; num++) {
            if (isValid(row, col, num)) {
                board[row][col] = num;
                if (solve()) {
                    return true;
                }
                board[row][col] = 0;
            }
        }
        return false;
    }

    private boolean isValid(int row, int col, int num) {
        for (int i = 0; i < 9; i++) {
            if (board[row][i] == num || board[i][col] == num) {
                return false;
            }
        }
        int boxRow = row - row % 3;
        int boxCol = col - col % 3;
        for (int i = boxRow; i < boxRow + 3; i++) {
            for (int j = boxCol; j < boxCol + 3; j++) {
                if (board[i][j] == num) {
                    return false;
                }
            }
        }
        return true;
    }

    public void print() {
        for (int i = 0; i < 9; i++) {
            if (i % 3 == 0 && i != 0) {
                System.out.println("- - - - - - - - - - - - -");
            }
            for (int j = 0; j < 9; j++) {
                if (j % 3 == 0 && j != 0) {
                    System.out.print("| ");
                }
                System.out.print(board[i][j] + " ");
            }
            System.out.println();
        }
    }

    public static void main(String[] args) {
        int[][] board = {
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0},
            {0, 0, 0, 0, 0, 0, 0, 0, 0}
        };
        SudokuSolver solver = new SudokuSolver(board);
        if (solver.solve()) {
            solver.print();
        }
    }
}

运行以上代码，将会得到一个空的数独盘面。你可以根据需要修改盘面上的数字，然后运行程序，程序将会自动填充剩余的数字，并输出结果。
