Question

Write a Java Program to place a pizza ordering program. It creates a pizza ordered to the specifications that the user desires. It walks the user through ordering, giving the user choices, which the program then uses to decide how to make the pizza and how much the cost of the pizza will be. Note: Use dialog boxes for communicating with the user. Remember to use the JOptionPane class which is the graphical user interface (GUI) and Comments that are not read by the computer, they are for use by the programmer. They are to help a programmer document what the program does and how it accomplishes it. This is important when a programmer needs to modify code that is written by another person.

Task 1. Name the program, PizzaOrder.java

2. Write a welcome message that said, “Welcome to ___________________ Pizza.”

3. Ask the user to input his or her first name. “Enter your first name:”

4. A menu should display to the user: Pizza sizes (inches) Cost 10” $10.99 12” $12.99 14” $14.99 16” $16.99 What size pizza would you like? 10, 12, 14, or 16 (enter the number only):

5. After the user has inputted the number another print statement should ask “What type of crust do you want? (H)Hand-tossed, (T) Thin-crust, or (D) Deepdish (enter H, T, or D):”

6. After the user has inputted the type of crust another print statement asking All pizzas come with cheese. Additional toppings are $1.25 each, choose from: Pepperoni, Sausage, Onion, Mushroom Do you want Pepperoni? (Y/N):

7. After you inputted Yes, or No another question should pop up Do you want Sausage? (Y/N): then Do you want Onion? (Y/N): then Do you want Mushroom? (Y/N):

8. At the end, it should show a receipt depending on the input: Note: The sales tax is 8.875% (below is an example) Your order is as follows:

10-inch Pizza

Hand-tossed crust $ 10.99

Pepperoni $ 1.25

The subtotal cost of your order is: $ 12.24

The tax is: $ 1.09 ----------------

total is: $ 13.33

*Your order will be ready for pick up in 30 minutes*
