Question

This is the question -

Create a class named Pizza with the following data fields:

description - of type String
price - of type double

The description stores the type of pizza (such as sausage and onion). Include a constructor that requires arguments for both fields and a method named display to display the data. For example, if the description is 'sausage and onion' and the price is '14.99', the display method should output:

sausage and onion pizza Price: $14.99

Create a subclass named DeliveryPizza that inherits from Pizza but adds the following data fields:

deliveryFee - of type double
address - of type String

The description, price, and delivery address are required as arguments to the constructor. The delivery fee is $3 if the pizza ordered costs more than $15; otherwise it is $5.

This is the code I have but the program does not like what I have especially the display parts-

public class DeliveryPizza extends Pizza

{

private double deliveryFee;

private String address;

public DeliveryPizza(String desc, double price, double deliveryFee, String address){

super(desc, price);

this.deliveryFee = deliveryFee;

this.address = address;

}

public void displayto(){

super.displayto();

System.out.println("Delivery Fee: "+deliveryFee+"\nAddress: "+address);

}

--------------------------------------

public class DemoPizzas {

public static void main(String args[]) {

// Write demo program here

DeliveryPizza pizza = new DeliveryPizza("sausage and oninon", 14.99, 3, "78/383 Milenium Street, WI");

pizza.displayto();

}

------------------------------------------

// Define the Pizza class here

private String description;

private double price;

public Pizza(String desc, double price) {

this.description = desc;

this.price = price;

}

public void displayto() {

System.out.printf("%s pizza Price: $%.2f\n", description, price);

}
