⑶ 如何使用java編寫一個會機器的聊天機器人
聊天機器人也就是socket和server,你在他們里邊都加上一個線程,互相監聽,通過輸入和輸出流傳遞信息內,然後你從容socket端輸入一句話,寫入流,然後server端讀取,處理一下再寫入流,然後你socket讀取,這就是一個簡單的相應了,server端就會等待socket端的下次相應,這太簡單了,估計網上不會有這樣的教程,你可以大致的參考一下這個思路
⑷ java編寫一個智能聊天機器人，請大神行行好寫個
簡單的可以使用HashMap把問答對應起來,一個問題可以有多個回答.然後隨機返回回1個
當然了這肯定不智能.只能簡單答玩玩.
需要復雜的聊天機器人,需要自然語義分析、機器學習和深度神經網路方面的技術
一個人獨立寫還是很困難的.
解決方案 :
調用第三方的聊天機器人介面
介面一般都是提交一個請求(請求的參數里包含你提交的問),返回一個jsON,然後從JSON里解析出想要的回答(字元串)就可以了
聊天機器人API或者聊天機器人介面網上有的
⑸ 用java編寫多人聊天室程序，不需要太復雜求大神發給我，最好能運行，有源代碼。謝謝了

⑺ 怎樣用Java程序編寫一個聊天機器人（自動和人聊天的程序）
是這樣的錯誤么？
Frist.java:5: cannot resolve symbol
symbol : class Scanner
location: class Frist
Scanner input=new Scanner(System.in);
Scanner是JDK1.5開始才有的
這樣的錯誤是因為JDK版本不夠，不支持。內。。
我用的就是1.4.2 所以是這容樣的錯誤
