Find Your Host Name/IP Address

     

In this section you will learn about the getLocalHost() method to print the Host name as well as the IP Address of the local system. For do for the same we have to call InetAddress class then we need to create a object, in which we store the local host information. Then after we use the print command to print the stored value of the InetAddress object local. The example for the above process is as under.

Here is the Code of the Example :

IPaddress.java

import java.net.*;

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

The output of the above example is as under, In which the host name of the local system is Comp20 and the IP address is 192.168.10.103.

Here is the Output of the Example :

C:\roseindia>javac Ipaddress.java

C:\roseindia>java Ipaddress
Local IP Address is : comp20/192.168.10.103
