Find Your Host Name

     

Here we are going to explore a method to retrieve the host name of the local system in a very simple example. Here we are just call the InetAddress class and after made a object of that class we call a getLocalHost() method and pass it in the object.

In this way we find out the ip address of the local system in a very simple manner. the complete code of the example is as under.

Here is the Code of the Example :

Hostname.java

import java.net.*;

public class Hostname{
  public static void main(String args[]){
  try{
  InetAddress local= InetAddress.getLocalHost();
  System.out.println ("Local hostname is: " + local.getHostName());
  }
  catch (UnknownHostException e){
  System.err.println ("Can't detect localhost : " + e);
  }
  }
}

The above example shows the host name of the local system. The output of the above example is as under, where the local hostname shows as comp20.

Here is the Output of the Example :

C:\roseindia>javac Hostname.java

C:\roseindia>java Hostname
Local hostname is: comp20
