這個(gè)是因?yàn)閹团笥炎鲎鳂I(yè)記錄一下，現(xiàn)場(chǎng)學(xué)習(xí)嗄，都忘了。好了不多說(shuō)了。

---

?1、首先得知道Swing，Swing是一個(gè)新型的java窗口工具(還是那么Love Orange W，哈哈哈)

2、聊天室怎么少得了Socket(套接字)

以上就是兩個(gè)窗口聊天的主要用到底工具(功能)

1、聊天室多人聊天的，所以我們會(huì)以客戶(hù)端和服務(wù)端兩端就夠了

2、我們開(kāi)始寫(xiě)服務(wù)端代碼，其實(shí)服務(wù)端和客戶(hù)端代碼都是一樣的，會(huì)一個(gè)就會(huì)兩個(gè)了，主要的就是在于區(qū)分Socket的端口與連接端口區(qū)別。不多bb了。上代碼

2.1、服務(wù)端的代碼
