Java簡(jiǎn)易qq聊天，代碼

這種東西，除非是網(wǎng)絡(luò)上原本就有的。否則你幾乎要不到的，即使是簡(jiǎn)易版想做出來(lái)，除非是高手，起碼要一個(gè)星期。

10年積累的成都網(wǎng)站設(shè)計(jì)、成都做網(wǎng)站經(jīng)驗(yàn)，可以快速應(yīng)對(duì)客戶對(duì)網(wǎng)站的新想法和需求。提供各種問(wèn)題對(duì)應(yīng)的解決方案。讓選擇我們的客戶得到更好、更有力的網(wǎng)絡(luò)服務(wù)。我雖然不認(rèn)識(shí)你，你也不認(rèn)識(shí)我。但先網(wǎng)站制作后付款的網(wǎng)站建設(shè)流程，更有柳南免費(fèi)網(wǎng)站建設(shè)讓你可以放心的選擇與我們合作。

關(guān)于仿QQ聊天對(duì)話框的JAVA代碼

1、swing的界面可以直接用netbeans畫(huà)出來(lái)嘛。

2、可以把輸出的聊天內(nèi)容都放在一個(gè)StringBuffer里，每打出一句話，就把這句話追加在StringBuffer，然后把StringBuffer里的內(nèi)容輸出到Textarea中。

3、好友列表可以用JList

怎樣用java 編寫(xiě)簡(jiǎn)易qq聊天工具？？？？

首先，學(xué)習(xí)java GUI編程，學(xué)習(xí)監(jiān)聽(tīng)器。建議看馬士兵的視頻。然后上網(wǎng)上down源代碼，分析類，確定類的屬性和方法。第一遍，就是跟著源碼敲一遍，然后分段看，一段一段的看懂，再實(shí)現(xiàn)。慢慢就會(huì)了。很有收獲滴！ 這是高仿QQ2012登錄界面 源代碼
