ID: 3595887 • Letter: A
Question
a. Create a method to calculate the price of a pizza and return it as a double. The method should take at least 3 parameters: Size, toppings, and crust style. Create an app which makes 3 pizzas and describes them at the console.
b. Create a method to validate a “coupon code” passed to it. The code should be a String and the method should return a double representing the value of the coupon. Pick a few “valid” codes and assign them each a discount value. Return 0.0 if the code is not valid. Create an app which makes 2 pizzas, one with a valid code and one without, and describes them at the console. GUI in Java
c. Create an app that uses the methods you created in #a and #b. Allow the user to enter values in four text fields for each of the parameters you need (size, toppings, crust style, and coupon code). Display the resulting price.

Q1. Pizza Maker on Console without GUI
public class MyPizza {
Map <String,Integer>topping=new HashMap<>();
Map <String,Integer>crust=new HashMap<>();
public double calcpizzaprice(int Size, String toppings, String cruststyle)
{
double price=0.0;
topping.put("mushrooms",23);
topping.put ("onion",24);
crust.put("cheese-burst",50);
crust.put ("wheat-thin-crust",60);
price=Size*(topping.get(toppings)+crust.get(cruststyle));
return price;
}
public static void main(String[] args)
{
MyPizza pizza1=new MyPizza();
MyPizza pizza2=new MyPizza();
System.out.println("------------------------------------------------------");
System.out.println("Total Prize is::"+pizza1.calcpizzaprice(2,"mushrooms","cheese-burst"));
System.out.println("------------------------------------------------------");
System.out.println("------------------------------------------------------");
System.out.println("Total Prize is::"+pizza1.calcpizzaprice(5,"onion","wheat-thin-crust"));
System.out.println("------------------------------------------------------");
}
