Package Imports

   Instead of importing each class you need individually, you can import an entire package by replacing the class name with an asterisk (*) like this:

import java.net.*;

public class URLSplitter {

  public static void main(String[] args) {
   
    for (int i = 0; i < args.length; i++) {
      try {
        URL u = new URL(args[i]);
        System.out.println("Protocol: " + u.getProtocol());
        System.out.println("Host: " + u.getHost());
        System.out.println("Port: " + u.getPort());
        System.out.println("File: " + u.getFile());
        System.out.println("Ref: " + u.getRef());
      }
      catch (MalformedURLException e) {
        System.err.println(args[i] + " is not a valid URL");
      }
    }
       
  }
}
