如何获得socket客户端的机器名？

Question

InetAddress addr=InetAddress.getLocalHost();
System.out.println(addr.getHostName());

Answer 1

InetAddress.getLocalHost获得的不是本地的地址吗？

Answer 2

import java.net.*;public class MyAddress
  {
     public static void main(String[] args)
       {
         try
          {
            InetAddress address=InetAddress.getLocalHost();
            System.out.println(address);
          }
        catch(UnknownHostException e)
          {
            System.out.println("Could not find this computer's address.");
           }
        }
    }
