Change and only show me the lines you changed inmy code. Modify my code to these instructions The project consists in creating an application that allows the cashier of a pizzeria to take the
pizzeria to take orders from customers and calculate their bill.
The application must contain two windows
The first (main) window must allow to enter the order of a customer thanks to
-Buttons
-comboBoxes
-The window must also contain labels that display the price of each menu
Example of an order
 2 Small pizzas with 6 toppings + 1 Large pizza with 2 toppings + 2 juices + 2 Pop
A button must allow to add the different types of pizza if the customer wants it
as in the example above.
Once the order is finished, a Pay button opens the second window
in which the details of the order are displayed.
A total button displays the invoice with taxes (13%).
Another Close button allows you to close the second window and return to the main window in order to
window to take another order.
Here are the prices of the menu
Pizza Prices:
Small: $6.79
Medium: $8.29
Large: $9.49
Extra Large: $10.29
Party Square: $15.99
Topping:
Small: $1.20
Medium: $1.40
Large: $1.60
Extra Large: $1.80
Party: $2.30
Drinks:
 Pop $1.10
Juice $1.35
Water $1.00
