通过IP地址连接

Question

我试图从文本文件中获取IP地址，所以当我使用下面的代码时，它确实没有工作..

  System.out.println("get = "+get);     //get is where the ip address is stored after reading from file and it is successfully received as well
  Socket client=new Socket(get,5000);

我甚至通过InetAddress尝试了同样的事情，如下所示..但它不能正常工作。

  InetAddress ik= InetAddress.getByName(get);
  Socket client=new Socket(ik,5000);    

但是当我手动提供ip时，它可以正常工作。我不明白我错在哪里？

  String get="192.168.1.224";

Answer 1

只是：

System.out.println("get = "+get.trim());
Socket client=new Socket(get,5000);
