import java.net.URL;

public class MainClass {

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

    URL u = new URL("http://www.java2s.com:80/index.html");
    System.out.println("The URL is " + u);

    String host = u.getHost();
    if (host != null) {
      int atSign = host.indexOf('@');
      if (atSign != -1)
        host = host.substring(atSign + 1);
      System.out.println("The host is " + host);
    } else {
      System.out.println("The host is null.");
    }

    System.out.println("The port is " + u.getPort());

  }

}

The scheme is http
The user info is null
The host is www.java2s.com
The port is 80
The path is /index.html
