adres IP

dlaczego nie wyswietla mi adresu IP?

import java.net.;
import java.io.;

public class Main
{
public static void main(String args[])
{
if(args.length < 1)
{
System.out.println("Wywolanie programu: Main www.google.pl");
System.exit(0);
}

	String host = args[0];
	InetAddress adres = null;
	
	try
	{
		adres = InetAddress.getByName(host);
	}
	
	catch(UnknownHostException e)
	{
		System.out.println("Nie mozna uzyskac adresu");
		System.exit(0);
	}
	
	String ip = adres.getHostAddress();
	System.out.println(host + " " + ip);
}

}

bo cię Java nie lubi? ;-P
