Try/Catch Unknown Host Exception

Question

I need to validate for an error of Unknown Host Exception, in case someone tries connected to a server that doesn't exist, or types the wrong host name, so i can display a message. how do I do that, with a try catch block.
I thought i would do:
try{
      my code here such as...
      DatagramSocket socket = new DatagramSocket();
      // send request
      InetAddress address = InetAddress.getByName(args[0]);
      DatagramPacket packet = new DatagramPacket(buf, buf.length, address, 4445);
      socket.send(packet);
    ...and so on, more code...
       socket.close();
} catch (IOException e) {
       e.printStackTrace();
       System.out.println("Unknown host " + args[0]);
}

Answer 1

thanks, i also had to take out the e.printStackTrace(); and replace that with
my error message and System.exit(0); and I got what i needed!
