java编译一个扫雷游戏程序

以下是一个简单的Java扫雷游戏程序的代码示例：

import java.util.Random;
import java.util.Scanner;

public class Minesweeper {
    private char[][] board;
    private boolean[][] revealed;
    private int rows, cols;
    private int remaining;

    public Minesweeper(int rows, int cols, int mines) {
        this.rows = rows;
        this.cols = cols;
        this.board = new char[rows][cols];
        this.revealed = new boolean[rows][cols];
        this.remaining = rows * cols - mines;

        // initialize board with empty cells
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < cols; j++) {
                board[i][j] = '.';
                revealed[i][j] = false;
            }
        }

        // randomly place mines on the board
        Random random = new Random();
        int count = 0;
        while (count < mines) {
            int i = random.nextInt(rows);
            int j = random.nextInt(cols);
            if (board[i][j] != '*') {
                board[i][j] = '*';
                count++;
            }
        }
    }

    public void play() {
        Scanner scanner = new Scanner(System.in);
        while (true) {
            // print board
            System.out.println(getBoardString());

            // get user input
            System.out.print("Enter row and column (e.g. 3 4): ");
            int row = scanner.nextInt() - 1;
            int col = scanner.nextInt() - 1;

            // check if cell is valid and not already revealed
            if (row < 0 || row >= rows || col < 0 || col >= cols) {
                System.out.println("Invalid cell, try again.");
                continue;
            }
            if (revealed[row][col]) {
                System.out.println("Cell already revealed, try again.");
                continue;
            }

            // reveal cell and update remaining count
            revealed[row][col] = true;
            if (board[row][col] == '*') {
                System.out.println("Boom! Game over.");
                return;
            } else {
                remaining--;
                if (remaining == 0) {
                    System.out.println("Congratulations! You win!");
                    return;
                }
            }

            // update adjacent cells
            if (board[row][col] == '.') {
                updateAdjacentCells(row, col);
            }
        }
    }

    private void updateAdjacentCells(int row, int col) {
        int[][] directions = {
            {-1, -1}, {-1, 0}, {-1, 1},
            {0, -1}, {0, 1},
            {1, -1}, {1, 0}, {1, 1}
        };
        for (int[] dir : directions) {
            int r = row + dir[0];
            int c = col + dir[1];
            if (r >= 0 && r < rows && c >= 0 && c < cols && board[r][c] == '*') {
                board[row][col]++;
            }
        }
    }

    private String getBoardString() {
        StringBuilder sb = new StringBuilder();
        sb.append("  ");
        for (int j = 0; j < cols; j++) {
            sb.append(j + 1);
        }
        sb.append("\n");
        for (int i = 0; i < rows; i++) {
            sb.append((char) ('A' + i)).append(" ");
            for (int j = 0; j < cols; j++) {
                if (revealed[i][j]) {
                    sb.append(board[i][j]);
                } else {
                    sb.append(".");
                }
            }
            sb.append("\n");
        }
        return sb.toString();
    }

    public static void main(String[] args) {
        Minesweeper game = new Minesweeper(8, 8, 10);
        game.play();
    }
}

这个程序使用了一个二维字符数组来表示扫雷的棋盘，其中`.`表示未翻开的空格，`*`表示地雷，数字表示该格周围地雷的数量。使用一个二维布尔数组来表示哪些格子已经被翻开了。程序会随机放置指定数量的地雷，然后让用户逐步翻开格子，直到所有非地雷格子都被翻开为止。如果翻开了地雷格子，游戏结束。如果所有非地雷格子都被翻开了，用户获胜。
