getLocalHost() shows wrong IP address

I am trying to execute following code. I am new to Java, so this is my first time in java.net. There is no error in program, but I am getting localhost address as 192.168.56.1 whereas my IP is 192.168.2.10

import java.net.*;
class InetAddressDemo
{
    public static void main(String[] args)
    {
        try
        {
            InetAddress address = InetAddress.getLocalHost();
            System.out.println("\nLocalhost Address : " + address + "\n");
        }
        catch (Exception e)
        {
            System.out.println(e);
        }
    }
}

A short answer, to get the IP Address that you already mention in your question you have to use :

String address = InetAddress.getLocalHost().getHostAddress();

You can find a good explanation about that here : Getting the IP address of the current machine using Java

You should enumerate network interfaces, since you may have multiple interfaces. getLocalHost() returns only the loopback address of your machine.

Enumeration Interfaces = NetworkInterface.getNetworkInterfaces();
while(Interfaces.hasMoreElements())
{
    NetworkInterface Interface = (NetworkInterface)Interfaces.nextElement();
    Enumeration Addresses = Interface.getInetAddresses();
    while(Addresses.hasMoreElements())
    {
        InetAddress Address = (InetAddress)Addresses.nextElement();
        System.out.println(Address.getHostAddress());
    }
 }
