            uri = new URI("https://Arnab_Kundu@www.geeksforgeeks.org");
            // get the  UserInfo
            String _UserInfo = uri.getUserInfo();
  
            // display the URI
            System.out.println("URI = " + uri);
  
            // display the  UserInfo
            System.out.println(" UserInfo=" + _UserInfo);
        }
        // if any error occurs

            // display the error
            System.out.println("URL Exception =" + e.getMessage());

Output:

URI = https://Arnab_Kundu@www.geeksforgeeks.org
 UserInfo=Arnab_Kundu

Example 2: The value returned by getUserInfo() and getRawUserInfo() is same except that all sequences of escaped octets are decoded. The getRawUserInfo() returns the exact value of the string as provided by the user but the getUserInfo() function decodes the sequence of escaped octets if any.
