Java实现俄罗斯方块游戏源代码（启动即可玩）

这是一个用Java Swing实现的俄罗斯方块游戏，具有经典的游戏机制和图形界面。游戏中，玩家需要旋转和移动不断下落的方块，使其填满一行来消除该行并得分。

该项目适合学习Java GUI编程、游戏开发基础以及面向对象编程（OOP）概念。

功能特性

图形界面：
- 使用Java Swing库实现用户界面。
- 提供直观的游戏界面，显示当前下落的方块和游戏得分。
游戏逻辑：
- 方块自动下落，玩家可以通过键盘控制方块的移动和旋转。
- 当方块填满一行时，该行会被消除，玩家得分增加。
- 游戏结束时，显示最终得分并停止游戏。
控件说明：
- 左右箭头键：移动方块左右。
- 上箭头键：旋转方块（顺时针）。
- 下箭头键：旋转方块（逆时针）。
- 空格键：快速下落方块。
- 'D'键：快速下降一行。
- 'P'键：暂停和继续游戏。
扩展性：
- 代码结构清晰，便于扩展和修改，例如添加新的方块形状或改变下落速度。
- 通过调整计时器的延迟，可以轻松改变游戏难度。

技术亮点

面向对象编程：
- 使用类和对象封装游戏中的方块形状、游戏逻辑和界面。
- 代码模块化，便于理解和维护。
事件驱动编程：
- 使用键盘事件和计时器事件控制游戏流程。
- 实现了对用户输入的实时响应，使游戏更加流畅。
Swing库的应用：
- 学习如何使用Swing库创建窗口、绘制图形、处理事件。
- 通过定制化绘制方法，展示不同颜色和形状的方块。
