1、本科畢業(yè)設(shè)計(論文)題目QQ:年級專業(yè)班級學號學生姓名指導教師職稱論文提交日期基于JAVA的聊天系統(tǒng)的設(shè)計與實現(xiàn)摘要網(wǎng)絡(luò)聊天工具已經(jīng)作為一種重要的信息交流工具,受到越來越多的網(wǎng)民的青睞。目前,出現(xiàn)了很多非常不錯的聊天工具,其中應(yīng)用比較廣泛的有Netmeeting、騰訊QQ、MSN-Messager等等。該系統(tǒng)開發(fā)主要包括一個網(wǎng)絡(luò)聊天服務(wù)器程序和一個網(wǎng)絡(luò)聊天客戶程序兩個方面。前者通過Socket套接字建立服務(wù)器,服務(wù)器能讀取、轉(zhuǎn)發(fā)客戶端發(fā)來信息,并能刷新用戶列表。后者通過與服務(wù)器建立連接,來進行客戶端
2、與客戶端的信息交流。其中用到了局域網(wǎng)通信機制的原理,通過直接繼承Thread類來建立多線程。開發(fā)中利用了計算機網(wǎng)絡(luò)編程的基本理論知識,如TCP/IP協(xié)議、客戶端/服務(wù)器端模式(Client/Server模式)、網(wǎng)絡(luò)編程的設(shè)計方法等。在網(wǎng)絡(luò)編程中對信息的讀取、發(fā)送,是利用流來實現(xiàn)信息的交換,其中介紹了對實現(xiàn)一個系統(tǒng)的信息流的分析,包含了一些基本的軟件工程的方法。經(jīng)過分析這些情況,該聊天工具采用Eclipse為基本開發(fā)環(huán)境和java語言進行編寫,首先可在短時間內(nèi)建立系統(tǒng)應(yīng)用原型,然后,對初始原型系統(tǒng)進行
