Java中基于TCPsocket的一對一簡單聊天室

1、江蘇經(jīng)貿職業(yè)技術學院信息技術學院2015-2016-2學年網(wǎng)絡編程技術（java）課程期末大作業(yè)姓 名：高文頂學 號：班 級：14網(wǎng)絡專 業(yè)：計算機網(wǎng)絡技術作品名稱：模仿QQ的簡單即時通信工具2016年4月一、程序功能簡介本程序擁有圖形界面和一對一聊天程序，實現(xiàn)監(jiān)聽連接、發(fā)送、退出功能。先啟動Server服務器端程序進行端口監(jiān)聽，然后啟動Client客戶端連接Server端IP地址和端口號，Server端監(jiān)聽到后顯示連接成功，可以進行通信。二、運行界面截圖（一）界面主程序（二）客戶端程序三、核心代碼說明（一）Client.java核心代碼說明示例package gwd;import java.
