Java制作一款扫雷游戏（含有源码）
Java制作一款扫雷游戏
题目
- 扫雷游戏分为初级、中级和高级三个级别，初级模式99个方块中有10个雷、中级模式1616个方块中有40个雷、高级模式16*30个方块中有99个雷，单击游戏菜单可以选择“开局”、“初级”、“中级”、“高级”或“退出”。
- 选择级别后出现相应雷区，若不选择默认初级模式，用户使用鼠标左键单击雷区中任一方块开始计时。
- 用户要揭开某个方块，单击它。若所揭方块下有雷，用户便输了这一局，若所揭方块下无雷，则显示一个数字，该数字代表方块的周围的8个方块中共有多少颗雷。
- 如果用户认为某个方块下埋着雷，右键单击该方块，方块将出现一个扫雷标记。用户每标记出一个扫雷标记（无论用户是否正确），程序将显示的剩余雷数减少一个。
- 准确地找出所有雷，将取得该局游戏的胜利。否则，将会弹出失败框。
