import java.net.InetSocketAddress;

import java.net.UnknownHostException;


public class Main {

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

        String hostAndPort = "nowjava.com";

        System.out.println(parse(hostAndPort));

    }


    public static InetSocketAddress parse(String hostAndPort)

            throws UnknownHostException {/**from n o w    j a v a  . c o m**/

        String[] strings = hostAndPort.split(":");
