隨著高校的信息化建設進程日益深入，計算機網絡技術的飛速發展，高校校園網建設的逐步完善，傳統的考試方式已經不能適應現代化考試的需要。開發基于 Java的在線考試系統，通過此軟件可以實現多學科網上在線考試，既能把教師從繁重的試卷命題、批閱試卷、試卷分析等工作中解放出來，又免去了印制紙質試卷、按考場分發試卷、紙質試卷保存等很多繁重工作，而且提高了試卷的保密性。本文設計了基于 C/S模式，采用了易于維護的文件來存儲試題和用戶，服務器采用 Java組件構成的考試系統，它運用方便、操 作簡單，效率很高。也就是說實現了真正的無紙化考試，滿足考生隨時隨地考試并迅速獲得成績，大大減輕了教師出題、組卷和改卷等繁重的工作量。 關鍵詞： 在線考試 。客戶 /服務器模式 。文件存儲 II The design and implementation of online examination system based on Java Author： WEI Zengli Instructor： BAI Ling Abstract: As colleges and universities information construction process is being more and more deeply， the rapid development of puter work technology， campus work construction of colleges and universities gradually improve， the traditional examination way already can not adapt to the need of modern test。 Development of online examination system based on Java， by this software can realize multidisciplinary online exam， can the teachers from the onerous paper proposition, marking examination papers, papers and tests, analysis, and was relieved from the printed paperbased test, according to the test venue distribution examination paper, paperbased test to save a lot of hard work， and improve the confidentiality of the test paper。 In this paper, based on C/S mode is designed， adopted the file to store the test question and the user easy to maintain， server using Java ponents of the test system， is it convenient to use, simple operation, high efficiency。 That is the real paperless examination， meet the candidates and quickly obtain test anytime and anywhere， greatly reduced the teacher, group volume and change the questions such as heavy workload。 Key words: The online test。C/S mode。File storage I 目 錄 引言
