URL: https://www.geeksforgeeks.org URI: https://www.geeksforgeeks.org
Example 2:
// Java program to convert URL to URI  import java.net.*;  class GFG {    public static void main(String args[])    {          // url and uri objects        URL url = null;        URI uri = null;          try {              // create an invalid URL              // display the URL            System.out.println("URL: " + url);              // convert the URL to URI            uri = url.toURI();              // display the URI            System.out.println("URI: " + uri);        }        // if any error occurs        catch (Exception e) {              // display the error            System.out.println(e);        }    }} |
