扫雷游戏是一种经典的计算机游戏，它要求玩家在一个网格中清除所有非地雷方块，同时避开地雷。下面是一个简单的Java实现，包括游戏界面、逻辑和用户交互。

1. 游戏设计

1.1 游戏规则

网格大小：10x10
地雷数量：随机生成
非地雷方块：显示数字表示周围地雷的数量
玩家可以通过点击方块来清除它
如果点击地雷，游戏结束
如果清除所有非地雷方块且没有点击地雷，游戏胜利

1.2 数据结构

int[][] grid：表示游戏网格
boolean[][] visited：表示方块是否被访问过
Random random：用于生成随机地雷

2. 游戏实现

2.1 初始化游戏

import java.util.Random;
import javax.swing.*;

public class Minesweeper {
    private static final int SIZE = 10;
    private static final int MINES = 10;
    private int[][] grid;
    private boolean[][] visited;
    private Random random;
    private JLabel[][] displayGrid;
    private JButton[] buttons;

    public Minesweeper() {
        grid = new int[SIZE][SIZE];
        visited = new boolean[SIZE][SIZE];
        random = new Random();
        displayGrid = new JLabel[SIZE][SIZE];
        buttons = new JButton[SIZE * SIZE];

        initializeGrid();
        initializeDisplay();
        initializeButtons();
    }

    private void initializeGrid() {
        for (int i = 0; i < SIZE class="hljs-keyword">for (int j = 0; j < SIZE xss=removed class="hljs-number">1 : 0;
            }
        }
    }

    private void initializeDisplay() {
        JFrame frame = new JFrame("Minesweeper");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLayout(new GridLayout(SIZE, SIZE));

        for (int i = 0; i < SIZE class="hljs-keyword">for (int j = 0; j < SIZE xss=removed class="hljs-keyword">new JLabel();
                displayGrid[i][j].setPreferredSize(new Dimension(50, 50));
                displayGrid[i][j].setBorder(BorderFactory.createLineBorder(Color.BLACK));
                frame.add(displayGrid[i][j]);
            }
        }

        frame.pack();
        frame.setVisible(true);
    }

    private void initializeButtons() {
        JPanel buttonPanel = new JPanel();
        buttonPanel.setLayout(new GridLayout(SIZE * SIZE, 1));

        for (int i = 0; i < SIZE xss=removed class="hljs-keyword">new JButton();
            buttons[i].addActionListener(e -> onClick(i / SIZE, i % SIZE));
            buttonPanel.add(buttons[i]);
        }

        JFrame frame = (JFrame) displayGrid[0][0].getParent();
        frame.add(buttonPanel, BorderLayout.SOUTH);
    }

    private void onClick(int row, int col) {
        if (grid[row][col] == -1) {
            JOptionPane.showMessageDialog(null, "Game Over!");
            return;
        }

        visited[row][col] = true;
        displayGrid[row][col].setText(String.valueOf(countAdjacentMines(row, col)));

        if (countAdjacentMines(row, col) == 0 && grid[row][col] == 0) {
            for (int i = 0; i < SIZE class="hljs-keyword">for (int j = 0; j < SIZE class="hljs-keyword">if (!visited[i][j] && grid[i][j] == 0) {
                        onClick(i, j);
                    }
                }
            }
        }
    }

    private int countAdjacentMines(int row, int col) {
        int count = 0;
        for (int i = -1; i <= 1; i++) {
            for (int j = -1; j <= 1; j++) {
                if (i == 0 && j == 0) continue;
                int newRow = row + i;
                int newCol = col + j;
                if (newRow >= 0 && newRow < SIZE>= 0 && newCol < SIZE xss=removed class="hljs-number">1) {
                    count++;
                }
            }
        }
        return count;
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> new Minesweeper());
