程序实现界面如下：
程序分析：本次作业基于上一次的数独作业，改正了数独生成个数0<N<1000000，并且代码已上传至conding,地址https://git.coding.net/dhlg_201810775002/shudu.git。
程序实现的功能：能生成正确的GUI界面，不同颜色位于空白处，并且可以选择相应的难易程度，开始玩数独游戏，当所有空白处填写正确后，会出现提示“恭喜你已完成此关卡”。
学习心得：第一次做GUI界面，查了很多资料和从网上百度经验，花费的时间较多。并将上一次作业没有实现的功能进行了改进，对GUI知识点进行了具体学习，如控件的设置学习，方法的实现等。希望下一次的作业能掌握更多的知识点，加强自身的学习。
