Pizza Order Application

Here we have created an application using graphical user interface that will allow the user to order the Pizza. For the pizza, it could be selected with a desired size, and toppings. Two types of toppings are available for selection with $0.25 for each Vegetarian topping and $0.50 for each Meat topping. Following sizes available for selection, with corresponding price:
· Small - $6.50
· Medium - $8.50
· Large - $12.50
· Extra Large - $16.00

If no size and no toppings were selected, a standard pizza would be ordered, where the size is small, and it contains only Cheese (same price as Extra Cheese). The user should be able to pay the total cost of the ordered pizza, with 7.75% tax added.

Here is the code:

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import java.text.*;
import javax.swing.*;

public class PizzaOrder extends JFrame implements ActionListener, KeyListener {
	double smallPizzaPrice = 6.50, mediumPizzaPrice = 8.50,
