Please, make sure response is with JOptionPane for dialog boxes.

I have a code, but cant figure it out with dialog boxes.

Write an application that displays a menu of three types of coffee for the Coffee Shop as follows:

American	$1.99
Espresso	2.50
Latte	2.15
Option:

Prompt the user to choose an item using the number (1, 2, 3 or 0) that corresponds to the item. If a different number s entered, then display an error message and finish the program. If the user types 1, 2, or 3, make a question: How many coffees?

After that, display the total cost for the coffee selected with a friendly message. Remember to use dialog box.
