java - 通过ip地址连接

Question

我正在尝试从文本文件中获取 IP 地址，因此当我使用以下代码时它不起作用..

  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);

我什至通过 InetAddress 尝试了同样的操作，如下所示..但效果不佳。

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

但是当我在 get 中手动提供 ip 时，它就可以工作了。我不明白我错在哪里？

  String get="192.168.1.224";

Answer 1

简单地说:

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