用Java写扫雷小游戏

好的，下面是一个简单的Java扫雷小游戏示例代码：

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

public class MineSweeper {
    private final int ROWS = 10;
    private final int COLS = 10;
    private final int MINES = 10;
    private int[][] board;
    private boolean[][] revealed;
    private boolean gameOver;
    
    public MineSweeper() {
        board = new int[ROWS][COLS];
        revealed = new boolean[ROWS][COLS];
        gameOver = false;
        initializeBoard();
    }
    
    private void initializeBoard() {
        Random random = new Random();
        int count = 0;
        while(count < MINES) {
            int row = random.nextInt(ROWS);
            int col = random.nextInt(COLS);
            if(board[row][col] == 0) {
                board[row][col] = -1;
                count++;
            }
        }
        for(int i = 0; i < ROWS; i++) {
            for(int j = 0; j < COLS; j++) {
                if(board[i][j] != -1) {
                    int countMines = 0;
                    if(i > 0 && j > 0 && board[i-1][j-1] == -1) countMines++;
                    if(i > 0 && board[i-1][j] == -1) countMines++;
                    if(i > 0 && j < COLS-1 && board[i-1][j+1] == -1) countMines++;
                    if(j > 0 && board[i][j-1] == -1) countMines++;
                    if(j < COLS-1 && board[i][j+1] == -1) countMines++;
                    if(i < ROWS-1 && j > 0 && board[i+1][j-1] == -1) countMines++;
                    if(i < ROWS-1 && board[i+1][j] == -1) countMines++;
                    if(i < ROWS-1 && j < COLS-1 && board[i+1][j+1] == -1) countMines++;
                    board[i][j] = countMines;
                }
            }
        }
    }
    
    private void reveal(int row, int col) {
        if(row < 0 || row >= ROWS || col < 0 || col >= COLS || revealed[row][col]) return;
        revealed[row][col] = true;
        if(board[row][col] == -1) {
            gameOver = true;
            return;
        }
        if(board[row][col] == 0) {
            reveal(row-1, col-1);
            reveal(row-1, col);
            reveal(row-1, col+1);
            reveal(row, col-1);
            reveal(row, col+1);
            reveal(row+1, col-1);
            reveal(row+1, col);
            reveal(row+1, col+1);
        }
    }
    
    private void displayBoard(boolean showMines) {
        System.out.print(" ");
        for(int j = 0; j < COLS; j++) {
            System.out.print(" " + (j+1));
        }
        System.out.println();
        for(int i = 0; i < ROWS; i++) {
            System.out.print((char)('A' + i));
            for(int j = 0; j < COLS; j++) {
                if(revealed[i][j] || showMines) {
                    if(board[i][j] == -1) {
                        System.out.print(" *");
                    } else {
                        System.out.print(" " + board[i][j]);
                    }
                } else {
                    System.out.print(" -");
                }
            }
            System.out.println();
        }
    }
    
    public void play() {
        Scanner scanner = new Scanner(System.in);
        while(!gameOver) {
            displayBoard(false);
            System.out.print("Enter row (A-J) and column (1-10): ");
            String input = scanner.nextLine();
            if(input.length() != 2) {
                System.out.println("Invalid input, try again.");
                continue;
            }
            int row = input.charAt(0) - 'A';
            int col = input.charAt(1) - '1';
            reveal(row, col);
        }
        displayBoard(true);
        System.out.println("Game over!");
        scanner.close();
    }
    
    public static void main(String[] args) {
        MineSweeper game = new MineSweeper();
        game.play();
    }
}

该示例代码中包含了以下功能：

- 随机生成雷区，并计算每个方格周围的雷数。
- 支持玩家揭示方格，如果揭示到雷则游戏结束。
- 在控制台中显示当前的雷区状态，包括已揭示的方格和未揭示的方格。
- 当游戏结束时，显示全部雷区的状态。

可以根据需要对该示例代码进行修改和扩展，例如增加计时器、记录最高分等功能。
