【導(dǎo)讀】基于JAVA實(shí)現(xiàn)聊天室。摘要隨著時(shí)代的發(fā)展時(shí)間信息兩個概念顯得越來越突出在第一時(shí)間掌握第。一手資料是打敗對手取得成功的秘訣伴隨著計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)的迅速發(fā)展通信業(yè)。也蒸蒸日上現(xiàn)在個人電腦已普及到各個家庭單位中為了能實(shí)時(shí)準(zhǔn)確地實(shí)現(xiàn)與朋。友親人同事之間的聯(lián)系網(wǎng)絡(luò)聊天是一種比較經(jīng)濟(jì)實(shí)惠的途徑其發(fā)展前景可觀。本系統(tǒng)利用Java中的socket網(wǎng)絡(luò)編程和多線程技術(shù)實(shí)現(xiàn)主要包括登陸連接。服務(wù)器管理客戶聊天三大功能管理員和用戶經(jīng)過登陸界面分別進(jìn)入到服務(wù)器端。和客戶端客戶通過socket連接服務(wù)器服務(wù)器通過多線程技術(shù)轉(zhuǎn)發(fā)信息到其他客。戶端這種服務(wù)器集中轉(zhuǎn)發(fā)信息的優(yōu)點(diǎn)是通信穩(wěn)定缺點(diǎn)是增加了服務(wù)器端的負(fù)擔(dān)。傳統(tǒng)的面對面之間的交流由于受地域和時(shí)間的影響已經(jīng)滿足不了當(dāng)今社會。的需求利用聊天室這種影響將會降到最小人與人之間的交流將會更加方便快捷。使用Java開發(fā)網(wǎng)絡(luò)程序在網(wǎng)絡(luò)飛速發(fā)展的今天已經(jīng)顯得格外重要與使用其。隨著網(wǎng)絡(luò)技術(shù)的發(fā)展和普及Inter已經(jīng)成為人們獲取有關(guān)信息和相互交
