我一直有一個與服務器套接字連接的問題，我有一個這個小遊戲的程序，並試圖使用套接字來獲得它連接，但是當我到達serverSocket = new ServerSocket(53000);它只是停止和凍結，doesn此後似乎沒有任何關係，或者採取任何聯繫。並且在kkSocket = new Socket(duke, 53000);之後，它剛好崩潰，似乎沒有連接，我確定我的防火牆沒有打開，我添加了互聯網權限，並且我嘗試了許多不同的設備名稱，我已將什麼我有我的設備命名，嘗試當前的IP地址，並沒有什麼會通過，我有一個銀河聯繫和nexus 7平板電腦，他們都有問題時，試圖溝通彼此，任何信息將是偉大的，謝謝。ServerSocket連接問題

使用try-catch語句來捕獲和顯示正在發生的任何錯誤，並縮小問題的位置。 – mittmemo
定義「它只是崩潰」。當你遇到異常時，不要自己編寫自己的消息，特別是那些像「其他錯誤」一樣平庸和無內容的消息。打印異常附帶的消息，最好是堆棧跟蹤。否則，你不知道發生了什麼問題，因爲你不知道。 – EJP
