高級軟件工程第三次做業：數獨遊戲界面功能

1、題目要求完成數獨遊戲界面功能，代碼已實現如下題目要求：

1. 生成任意數量的數獨題目並將數獨棋局依次顯示，棋盤上總空格數大於30，小於60，每3*3小棋盤中挖空很多於2個。
2. 數獨題目有且僅有惟一解。
3. 用戶能夠在界面上經過編輯輸入完成數獨題目。
4. 用戶完成數獨題目後能夠獲得正確性反饋。
5. 友好的使用說明

2、遊戲界面實現效果：

一、遊戲界面設計：用戶填完數獨棋盤，點擊提交按鈕提交後程序會顯示成功和失敗（見截圖），若是屢次失敗能夠查看當前棋盤的答案顯示，並進入下一輪遊戲。

二、正確反饋：

三、錯誤反饋：

3、心得體會：

     第一次作小遊戲的GUI界面，網上查了不少資料，也找了一些基礎的視頻來學習，花費時間較多，最後遊戲的結果還算滿意。主要學習了Javax的組件，如：Container c = getContentPane()，由於JAVAX組件不能直接加到JFRAME上，須要用JFRAM的getContentPane 得到其組件層（javax組件5層之一），而它返回的是個容器，因此用Container c來保存等等，作的過程當中發現自身不足較多，後續還須要更多的學習和練習。
