object-oreinted programming.

Upon the ordering transaction, display the order details in the tabular format and save the
order data to a text file for historical purposes. The order ID will be generated automatically
using a sequential number and prefixed with the letter 'P'. Save the order date with the current
date. You may use the Calendar class in Java to derive the current date. Apply 5% government
sales tax to the gross total of the transaction.

Figure 3: Pizza Order Page
The user may select option 2 in the main menu to view back the previous order details by
entering the Order ID. In this case, you should design a class called Order to capture all the
information stated in Figure 3.0. Users can place a maximum of up to 8 pizzas per order. You
may create another class called OrderLine to present each ordered pizza details (e.g. Deluxe
Cheese-L and quantity 2) in an order.
Currently, all the pizza information is saved into a file called pizza.txt. Create a Pizza entity
class to capture the pizza details. The Pizza class should have a name and a price for each
different size. Certain pizzas might have different prices although with the same size. There
are 4 different prices for each pizza separated by a comma in the file. The following record
represents P-8.9, R-16.0, L-26.0 and XL-36.0.
Blazing Seafood, 8.9,16.0,26.0,36.0
However, certain pizza does not have the price for the personal pizza and the system will
simply place a zero in the record. Hence, users are not allowed to select their personal pizza
on the ordering page. While the program is launched, you are required to load and populate
all the pizza details from the given pizza.txt file to the object array.
For option 3, the user can add new pizza details including the prices for each pizza size and
update the pizza.txt file.
Validation should be done for each transaction to avoid logical errors (e.g. prevent negative
value for the chocolate weight). Application of advanced OOP concepts such as Inheritance,
composition & aggregation will gain higher marks in the overall assessment.

You are about to create a prototype of a Pizza Ordering system using the Java programming
language. Create a simple user interface of the program (figure 1.0) in the console mode
environment. The initial interface is as follows:
Pizza Ordering System
1
1
1
1
1 [Order Pizza
2 [View Order
3 [Add New Pizza
4 [Exit
Enter Option: 1
Figure 1: Main Menu
Use a loop to allow the user to select the option repeatedly until the [Exit] option was selected.
When the user selects option 1, a new menu as shown in Figure 2.0 will be displayed to allow
the user to select the type pizza, size and quantity of the pizza.
<<Pizza Menu>>
