How to obtain full host name?

Question

when I write following code in cmd:

ping localhost

I see following result:

Pinging hostname.A.B.com [::1] with 32 bytes of data:
Reply from ::1: time<1ms
Reply from ::1: time<1ms
Reply from ::1: time<1ms
Reply from ::1: time<1ms

When I write

InetAddress.getLocalHost().getCanonicalHostName();

it returns only hostname

How can I achieve to return hostname.A.B.com from java code ?

P.S.

It is not duplicate. I use code from top answer but I don't achieve desired result.

In your case, you grab the localhost address InetAddress.getLocalHost() so if you haven't put your fully qualified name for your host, you only get the hostname. In linux (and probably OS X and other UNIX system), you need to add your qualified hostname to /etc/hosts to your localhost entry for this to work.
