What's wrong here..

[Mahajan Bhupendra]

hi just now i have started the java.net
and the very first program give me an error
my program is ..

 import java.net.*;
class InetAddressTest {
 public static void main(String args[]) throws UnknownHostException {
InetAddress address=InetAddress.getLocalHost();
System.out.println(address);
address=InetAddress.getByName("www.rediff.com");
System.out.println(address);
 }
} 

it's giving me error..
computer1/200.200.200.38
Exception in thread "main" java.net.UnknownHostException: www.rediff.com
at java.net.InetAddress.getAllByName0(Unknown Source)
at java.net.InetAddress.getAllByName0(Unknown Source)
at java.net.InetAddress.getByName(Unknown Source)
at InetAddressTest.main(InetAddressTest.java:7)

i think it is beacause in our office we are having LAN and server is having NT4.0 with service pack 6..
is the problem beacuse of LAN or anything wrong in a program itself..

Hi,
The error message tells you what is wrong.
Exception in thread "main" java.net.UnknownHostException: www.rediff.com.
Your network does not know what "www.rediff.com" is(Unknown host). It is like you type some address and your browser returns you a Page Not Found message.
btw, your code works fine on my machine and I got the output:
www.rediff.com/64.41.191.70
Ping

we use internet frequently as we have a common connection to server and wingate(software that distributes internet to LAN clients)...
so if i type rediff.com in by browser i didn't get any error but the web site...
what should be the problem???

I'm just wondering, if main() can throw any exception. Maybe you can't change the signature. It is and always should be: public static void main(String args[])
