Get Local Host Name

In this Example we want to describe you a code that helps you in understanding a code how to 'Get Local Host Name'. For this we have a class name GetLocalHostName. Inside the main method we have -

For this we have a class name GetLocalHost,Inside the main method we have a class NetworkInterface,this class represents a Network Interface made up of a name and a list of IP addresses assigned to this interface. This is used to identify the list of multicast group joined to identify the local interface.

1)getNetworkInterface( ) - This method returns you the interface used on this machine.

The System.outprintln print the interface name by calling the get Display Name ( ) method.

2)getDisplayName ( ) - This method returns you name of the network interface.

3)getInet Addresses( ) - This method returns you Enumeration with all the subset of the Inet addresses bound to this network interface.

4)get Host Name( ) - This method returns you the information about the hostname for the current machine.

5)get Host Address( ) -This method return you the address of the host.

The inet Address class provides you the IP address of the current system.

GetLocalHostName.java

import java.net.*;
import java.util.*;

public class GetLocalHostName {

public static void main(String args[]) throws Exception {

  Enumeration<NetworkInterface> nets =
NetworkInterface.getNetworkInterfaces();

0 for (NetworkInterface netint : Collections.list(nets)) {
  System.out.println("\nInterface Name : " + netint.getDisplayName());

  Enumeration<InetAddress> inetAddresses = netint.getInetAddresses();

for (InetAddress inetAddress : Collections.list(inetAddresses)) {

   System.out.println("Local host Name\t: " + inetAddress.getHostName());
   System.out.println("Host Address\t: " + inetAddress.getHostAddress());
  }
  }
  }
}

Output:

Interface name : MS TCP Loopback interface
Local host name : localhost
Host Address  : /127.0.0.1

Display name  : Intel(R) PRO/100 VE Network Connection -
Packet Scheduler Miniport
Local host name : SAM
