import java.net.*; 
  
class Solution { 
    public static void main(String args[]) 
    { 
        // url  object 
        URL url = null; 
  
        try { 
            // create a URL 
            url = new URL("https:// www.geeksforgeeks.org"); 
  
            // get the  ExternalForm 
            String _ExternalForm = url.toExternalForm(); 
  
            // display the URL 
            System.out.println("URL = " + url); 
  
            // display the  ExternalForm 
            System.out.println(" String representation= "
                               + _ExternalForm); 
        } 
        // if any error occurs 
        catch (Exception e) { 
  
            // display the error 
            System.out.println(e); 
        } 
    } 
}

輸出：

URL = https:// www.geeksforgeeks.org
 String representation= https:// www.geeksforgeeks.org

範例2：

            // get the  ExternalForm 
            String _ExternalForm = url.toExternalForm(); 
  
            // display the URL 
            System.out.println("URL = " + url); 
  
            // display the  ExternalForm 
            System.out.println(" String representation= "
                               + _ExternalForm); 
        } 
  
        // if any error occurs 
        catch (Exception e) {
