練習2：采用GUI界面設計以下程序：

l?編制一個程序，將身份證號.txt?中的信息讀入到內存中；

l?按姓名字典序輸出人員信息；

l?查詢最大年齡的人員信息；

l?查詢最小年齡人員信息；

l?輸入你的年齡，查詢身份證號.txt中年齡與你最近人的姓名、身份證號、年齡、性別和出生地；

l?查詢人員中是否有你的同鄉。

l?輸入身份證信息，查詢所提供身份證號的人員信息，要求輸入一個身份證數字時，查詢界面就顯示滿足查詢條件的查詢結果，且隨著輸入的數字的增多，查詢匹配的范圍逐漸縮小。

練習3：采用GUI界面設計以下程序

l?編寫一個計算器類，可以完成加、減、乘、除的操作

l?利用計算機類，設計一個小學生100以內數的四則運算練習程序，由計算機隨機產生10道加減乘除練習題，學生輸入答案，由程序檢查答案是否正確，每道題正確計10分，錯誤不計分，10道題測試結束后給出測試總分；

l?將程序中測試練習題及學生答題結果輸出到文件，文件名為test.txt。

任務3：本學期課程已結束，請匯總《面向對象程序設計課程學習進度條》的數據，統計個人專業能力提升的數據。并從學習內容、學習方法、學習心得幾個方面進行課程學習總結，也希望你對課程的不足提出建議和意見。

實驗總結：

一學期的java課結束了，收獲還是挺多的，以后在空閑時間還會繼續學習java。
