用java写一个拼图游戏代码

好的，以下是一个简单的拼图游戏Java代码：

import java.util.*;

public class PuzzleGame {
    
    public static void main(String[] args) {
        int[][] board = {{1, 2, 3}, {4, 5, 6}, {7, 8, 0}}; //初始状态
        shuffle(board); //打乱拼图
        int steps = playGame(board); //开始游戏
        System.out.println("完成游戏，步数为：" + steps);
    }
    
    //打乱拼图
    public static void shuffle(int[][] board) {
        Random rand = new Random();
        for (int i = board.length - 1; i > 0; i--) {
            for (int j = board[0].length - 1; j > 0; j--) {
                int x = rand.nextInt(i+1);
                int y = rand.nextInt(j+1);
                int temp = board[i][j];
                board[i][j] = board[x][y];
                board[x][y] = temp;
            }
        }
    }
    
    //开始游戏，返回步数
    public static int playGame(int[][] board) {
        int steps = 0;
        while (!isFinished(board)) {
            printBoard(board);
            System.out.print("请输入要移动的数码（1-8）：");
            Scanner sc = new Scanner(System.in);
            int num = sc.nextInt();
            if (moveTile(board, num)) {
                steps++;
            } else {
                System.out.println("移动失败，请重新输入！");
            }
        }
        return steps;
    }
    
    //判断是否完成游戏
    public static boolean isFinished(int[][] board) {
        int count = 1;
        for (int i = 0; i < board.length; i++) {
            for (int j = 0; j < board[0].length; j++) {
                if (board[i][j] != count) {
                    return false;
                }
                count++;
            }
        }
        return true;
    }
    
    //移动数码
    public static boolean moveTile(int[][] board, int num) {
        int row = -1, col = -1;
        for (int i = 0; i < board.length; i++) {
            for (int j = 0; j < board[0].length; j++) {
                if (board[i][j] == num) {
                    row = i;
                    col = j;
                    break;
                }
            }
        }
        if (row == -1 || col == -1) {
            return false; //数码不存在
        }
        if (row > 0 && board[row-1][col] == 0) { //向上移动
            board[row-1][col] = num;
            board[row][col] = 0;
            return true;
        } else if (row < board.length-1 && board[row+1][col] == 0) { //向下移动
            board[row+1][col] = num;
            board[row][col] = 0;
            return true;
        } else if (col > 0 && board[row][col-1] == 0) { //向左移动
            board[row][col-1] = num;
            board[row][col] = 0;
            return true;
        } else if (col < board[0].length-1 && board[row][col+1] == 0) { //向右移动
            board[row][col+1] = num;
            board[row][col] = 0;
            return true;
        }
        return false; //移动失败
    }
    
    //输出当前状态
    public static void printBoard(int[][] board) {
        System.out.println("当前状态：");
        for (int i = 0; i < board.length; i++) {
            for (int j = 0; j < board[0].length; j++) {
                System.out.print(board[i][j] + " ");
            }
            System.out.println();
        }
    }
}

请注意，这只是一个简单的示例，实际上，拼图游戏需要实现更复杂的算法和图形界面。如果您有其他问题或需要更详细的解释，请随时问我。
