Create a GUI (Graphical User Interface) Program named Order Total for the ABC Bookstore, Inc. in USA. The program prompts the user for the number of a newly published science fiction book ordered at $22.00 each. The program must perform the following tasks:

1. Calculate the amount due before tax (defined as number ordered times price each), the net due (defined as amount due before tax, plus tax (8.25%)). Use a separate method for calculating the order total (3 points). Also, use exception handler to throw a message if the user input is invalid (2 points).

2. Display the order total (formatted as currency)
