基于JAVA写一个扫雷小游戏

好的，下面是一个简单的基于Java的扫雷小游戏示例代码，供您参考。

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

public class Minesweeper {
    private int[][] board; // 存储格子状态和雷的位置
    private boolean[][] visible; // 存储格子是否被翻开
    private int n; // 游戏区域大小
    private int mines; // 雷的数量
    private int remaining; // 剩余未翻开的格子数

    // 初始化游戏
    public Minesweeper(int n, int mines) {
        this.n = n;
        this.mines = mines;
        remaining = n * n - mines;

        board = new int[n][n];
        visible = new boolean[n][n];

        // 初始化雷的位置
        Random rand = new Random();
        for (int i = 0; i < mines; i++) {
            int x = rand.nextInt(n);
            int y = rand.nextInt(n);
            if (board[x][y] != -1) {
                board[x][y] = -1;
            } else {
                i--;
            }
        }

        // 计算每个方格周围雷的数量
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < n; j++) {
                if (board[i][j] != -1) {
                    int count = 0;
                    for (int di = -1; di <= 1; di++) {
                        for (int dj = -1; dj <= 1; dj++) {
                            int ni = i + di;
                            int nj = j + dj;
                            if (ni >= 0 && ni < n && nj >= 0 && nj < n && board[ni][nj] == -1) {
                                count++;
                            }
                        }
                    }
                    board[i][j] = count;
                }
            }
        }
    }

    // 根据坐标翻开格子
    public boolean reveal(int x, int y) {
        if (board[x][y] == -1) {
            return false;
        }
        visible[x][y] = true;
        remaining--;
        if (board[x][y] == 0) {
            for (int di = -1; di <= 1; di++) {
                for (int dj = -1; dj <= 1; dj++) {
                    int ni = x + di;
                    int nj = y + dj;
                    if (ni >= 0 && ni < n && nj >= 0 && nj < n && !visible[ni][nj]) {
                        reveal(ni, nj);
                    }
                }
            }
        }
        return true;
    }

    // 打印游戏状态
    public void print() {
        System.out.print("  ");
        for (int j = 0; j < n; j++) {
            System.out.print(j + " ");
        }
        System.out.println();
        for (int i = 0; i < n; i++) {
            System.out.print(i + " ");
            for (int j = 0; j < n; j++) {
                if (visible[i][j]) {
                    if (board[i][j] == -1) {
                        System.out.print("* ");
                    } else {
                        System.out.print(board[i][j] + " ");
                    }
                } else {
                    System.out.print(". ");
                }
            }
            System.out.println();
        }
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入游戏区域大小: ");
        int n = scanner.nextInt();
        System.out.print("请输入雷的数量: ");
        int mines = scanner.nextInt();
        Minesweeper game = new Minesweeper(n, mines);
        game.print();

        while (game.remaining > 0) {
            System.out.print("请输入要翻开的格子坐标(x y): ");
            int x = scanner.nextInt();
            int y = scanner.nextInt();
            if (!game.reveal(x, y)) {
                System.out.println("你输了!");
                return;
            }
            game.print();
        }
        System.out.println("你赢了!");
    }
}

这个示例代码实现了一个基于控制台的扫雷小游戏，玩家可以输入坐标来翻开格子，并且会打印出当前游戏状态。还有很多可以改进的地方，比如添加计时、排行榜等功能。
