扫雷小游戏java代码

下面是一个简单的扫雷小游戏的Java代码示例：

import java.util.*;

public class Minesweeper {
    private static final int SIZE = 10;
    private static final int MINE_COUNT = 10;
    private static final char UNKNOWN = '-';
    private static final char MINE = '*';
    private static final char EXPLORED = ' ';
    
    public static void main(String[] args) {
        char[][] board = initializeBoard();
        placeMines(board);
        playGame(board);
    }
    
    public static char[][] initializeBoard() {
        char[][] board = new char[SIZE][SIZE];
        for (char[] row : board) {
            Arrays.fill(row, UNKNOWN);
        }
        return board;
    }
    
    public static void placeMines(char[][] board) {
        Random rand = new Random();
        int count = 0;
        while (count < MINE_COUNT) {
            int row = rand.nextInt(SIZE);
            int col = rand.nextInt(SIZE);
            if (board[row][col] != MINE) {
                board[row][col] = MINE;
                count++;
            }
        }
    }
    
    public static void playGame(char[][] board) {
        Scanner scanner = new Scanner(System.in);
        int exploredCount = 0;
        
        while (exploredCount < SIZE * SIZE - MINE_COUNT) {
            printBoard(board);
            
            System.out.print("请输入要探索的行坐标：");
            int row = scanner.nextInt();
            System.out.print("请输入要探索的列坐标：");
            int col = scanner.nextInt();
            
            if (board[row][col] == MINE) {
                System.out.println("你被炸死了！");
                break;
            }
            
            explore(board, row, col);
            exploredCount++;
        }
        
        if (exploredCount == SIZE * SIZE - MINE_COUNT) {
            System.out.println("恭喜你，你赢了！");
        }
    }
    
    public static void explore(char[][] board, int row, int col) {
        if (board[row][col] != UNKNOWN) {
            return;
        }
        
        int count = 0;
        
        for (int i = -1; i <= 1; i++) {
            for (int j = -1; j <= 1; j++) {
                if (isValidCell(row + i, col + j) && board[row + i][col + j] == MINE) {
                    count++;
                }
            }
        }
        
        if (count == 0) {
            board[row][col] = EXPLORED;
            
            for (int i = -1; i <= 1; i++) {
                for (int j = -1; j <= 1; j++) {
                    if (isValidCell(row + i, col + j)) {
                        explore(board, row + i, col + j);
                    }
                }
            }
        } else {
            board[row][col] = (char) (count + '0');
        }
    }
    
    public static boolean isValidCell(int row, int col) {
        return (row >= 0 && row < SIZE && col >= 0 && col < SIZE);
    }
    
    public static void printBoard(char[][] board) {
        System.out.println("当前棋盘状态：");
        
        for (char[] row : board) {
            for (char cell : row) {
                System.out.print(cell + " ");
            }
            System.out.println();
        }
    }
}

这个游戏使用字符数组表示游戏棋盘，其中未探索的单元格用"-"表示，雷的位置用"*"表示，已探索的单元格用空格表示，数字表示周围有多少个雷。游戏开始时，先生成一个大小为10x10的棋盘，并在随机位置放置10个雷。然后玩家依次输入要探索的行坐标和列坐标，程序会判断该位置是否有雷，如果有就游戏结束，否则会根据该位置周围雷的数量进行递归探索。如果玩家成功找出所有的非雷单元格，那么游戏胜利。
