高级软件工程第三次作业：数独游戏界面功能
一、题目要求完成数独游戏界面功能，代码已实现以下题目要求：
- 生成任意数量的数独题目并将数独棋局依次显示，棋盘上总空格数大于30，小于60，每3*3小棋盘中挖空不少于2个。
- 数独题目有且仅有唯一解。
- 用户可以在界面上通过编辑输入完成数独题目。
- 用户完成数独题目后可以得到正确性反馈。
- 友好的使用说明

二、游戏界面实现效果：
1、游戏界面设计：用户填完数独棋盘，点击提交按钮提交后程序会显示成功和失败（见截图），如果多次失败可以查看当前棋盘的答案显示，并进入下一轮游戏。
2、正确反馈：
3、错误反馈：
三、心得体会：
第一次做小游戏的GUI界面，网上查了很多资料，也找了一些基础的视频来学习，花费时间较多，最后游戏的结果还算满意。主要学习了Javax的组件，如：Container c = getContentPane()，因为JAVAX组件不能直接加到JFRAME上，需要用JFRAM的getContentPane 获得其组件层（javax组件5层之一），而它返回的是个容器，所以用Container c来保存等等，做的过程中发现自身不足较多，后续还需要更多的学习和练习。
