Java Socket線程的設計原理介紹
Java Socket線程我們經(jīng)常會用到的技術，但是有很多程序員還是有不少的使用問題，下面我們就看看如何才能進行有關的代碼編寫，希望大家又說收獲。網(wǎng)絡的偉大之一也是信息共享，Server可以主動向所有Client廣播消息，同時Client也可以向其它Client發(fā)布消息。
成都創(chuàng)新互聯(lián)公司是一家以成都網(wǎng)站建設公司、網(wǎng)頁設計、品牌設計、軟件運維、網(wǎng)站推廣、小程序App開發(fā)等移動開發(fā)為一體互聯(lián)網(wǎng)公司。已累計為成都格柵板等眾行業(yè)中小客戶提供優(yōu)質(zhì)的互聯(lián)網(wǎng)建站和軟件開發(fā)服務。
下面看看如何開發(fā)一個可以實時傳遞消息的程序。
Java Socket線程的設計原理：
服務器端接受客戶端的連接請求，同時啟動一個線程處理這個連接，線程不停的讀取客戶端輸入，然后把輸入加入隊列中，等候處理。在線程啟動的同時將線程加入隊列中，以便在需要的時候定位和取出。

以上就是對Java Socket線程的詳細介紹。這就是程序運行后，多用戶登陸并且輸入信息后的屏幕。實現(xiàn)了信息的實時廣播。用戶輸入"l"就可以列出在線人員表。
