練習2：採用GUI介面設計以下程式：
編制一個程式，將身份證號.txt 中的資訊讀入到記憶體中；
按姓名字典序輸出人員資訊；
查詢最大年齡的人員資訊；
查詢最小年齡人員資訊；
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；
查詢人員中是否有你的同鄉。
輸入身份證資訊，查詢所提供身份證號的人員資訊，要求輸入一個身份證數字時，查詢介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，查詢匹配的範圍逐漸縮小。

練習3：採用GUI介面設計以下程式
編寫一個計算器類，可以完成加、減、乘、除的操作
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式，由計算機隨機產生10道加減乘除練習題，學生輸入答案，由程式檢查答案是否正確，每道題正確計10分，錯誤不計分，10道題測試結束後給出測試總分；
將程式中測試練習題及學生答題結果輸出到檔案，檔名為test.txt。

學習方法：
1.理論課：老師課堂講解基礎知識
2.實驗課：老師和助教學長演示程式並進行講解。
3.課下自主學習：
（1）結合課本內容和相關的示例程式，並自主查閱資料，完成程式設計練習。
（2）程式設計練習完成後，助教進行答疑講解；老師根據作業中的問題，在課堂上進行講解。
學習心得：
通過本學期的學習，我從一開始的對Java完全沒有概念到慢慢的瞭解並學習到它的應用，但仍感覺在知識的邊緣探索，
沒有很深入的學習到它的真正運用價值，雖然在理論上的學習尚且能聽懂，但還是不會將它應用到程式設計中，實現一個問題的解決程式。
老師和學長還介紹了Java在未來的學習方向和發展，日後還是很有必要更深入更熟練的去學習運用Java知識。
個人認為老師的教學方式很好，在講解示例程式碼之後再讓我們去通過執行結果學習每一個細節是通過什麼方法來實現的，希望老師可以在課堂上多講一點示例程式。
最後，由衷感謝老師的諄諄教導和學長的耐心講解，讓我收穫到了很多有用的知識和道理。
