Question

Hello can someone help me in my code I left it as comment  task #0, task#1, task#2a and task#2b the things that I am missing I'm using java

domain class

public class Pizza
{
private String pizzaCustomerName;
private int pizzaSize; // 10, 12, 14, or 16 inches in diameter
private char handThinDeep; // 'H' or 'T' or 'D' for hand tossed, thin crust, or deep dish, respecitively
private boolean cheeseTopping;
private boolean pepperoniTopping;
private boolean sausageTopping;
private boolean onionTopping;
private boolean mushroomTopping;
  
public Pizza(String aPizzaCustomerName, int aSize, char aPizzaType, boolean aCheeseTopping, boolean aPepperoniTopping, boolean aSausageTopping, boolean aOnionTopping, boolean aMushroomTopping)
{
  
pizzaCustomerName = aPizzaCustomerName;
pizzaSize = aSize;
handThinDeep = aPizzaType;
cheeseTopping = aCheeseTopping;
pepperoniTopping = aPepperoniTopping;
sausageTopping = aSausageTopping;
onionTopping = aOnionTopping;
mushroomTopping = aMushroomTopping;
}
  

The rest I can add says it's too big

Answer 1

/Task #0: Write the if-statements to set the value of the cheeseTopping boolean flags to true or false, depending on
// whether the user says Yes or No. Use charAt(0) to get the first letter of their response, and check for
// an uppercase and a lowercase version of the first letter ('Y' or 'y')
// Continue asking the user about all the other toppings (pepperoni, onion, sausage, mushroom), and setting the appropriate flags to true or false

Task #0 Implementation

Above the task #0, we have read the value of user input for additional cheese, now we have to check the user input, if it is Yes or 'Y', we need to set the cheeseTopping to true, otherwise false. We can code this as below:

       if (userInput.charAt(0) == 'y' || userInput.charAt(0) == 'Y') {
            cheeseTopping = true;
        } else {
            cheeseTopping = false;
        }

Now, similarly we need to continue asking the user for other topping too, and get the user input. And as per their input, we need to set respective flags:

       userInput = JOptionPane.showInputDialog("Would you like pepperoni?");
        if (userInput.charAt(0) == 'y' || userInput.charAt(0) == 'Y') {
            pepperoniTopping = true;
        } else {
            pepperoniTopping = false;
        }

        userInput = JOptionPane.showInputDialog("Would you like sausage?");
        if (userInput.charAt(0) == 'y' || userInput.charAt(0) == 'Y') {
            sausageTopping = true;
        } else {
            sausageTopping = false;
        }

        userInput = JOptionPane.showInputDialog("Would you like onion?");
        if (userInput.charAt(0) == 'y' || userInput.charAt(0) == 'Y') {
            onionTopping = true;
        } else {
            onionTopping = false;
        }

        userInput = JOptionPane.showInputDialog("Would you like mushroom?");
        if (userInput.charAt(0) == 'y' || userInput.charAt(0) == 'Y') {
            mushroomTopping = true;
        } else {
            mushroomTopping = false;
        }

// Task #1: Create an instance of aPizzaOrder by invoking the constructor, and passing it the values in firstName, pizzaSizeInInches, pizzaType, cheeseTopping, pepperoniTopping, sausageTopping, onionTopping, mushroomTopping.

Task #1 Implementation

We need to create an instance of aPizzaOrder which is an object of Pizza class, so to instantiate the instance, we need to use the new keyword and call the constructor of Pizza class by passing all the parameter values that we have calculated in above task. So, it can be done as:

aPizzaOrder = new Pizza(firstName, pizzaSizeInInches, pizzaType, cheeseTopping, pepperoniTopping, sausageTopping, onionTopping, mushroomTopping);

//Task #2a: Determine how many more toppings and concatenate them to the toppings String variable, and add 1 to numberOfToppings for each topping:

Task #2a Implementation

The statement written above this task, checks if order has cheese topping, if it is, we need to increase the numberOfToppings by 1 and add topping name in the topping string. Similarly, we need to do for other topping options like below:

        if(aPizzaOrder.getPepperoniTopping()){
            numberOfToppings += 1;
            toppings = toppings + "Pepperoni ";
        }
        if(aPizzaOrder.getSausageTopping()){
            numberOfToppings += 1;
            toppings = toppings + "Sausage ";
        }
        if(aPizzaOrder.getOnionTopping()){
            numberOfToppings += 1;
            toppings = toppings + "Onion ";
        }
        if(aPizzaOrder.getMushroomTopping()){
            numberOfToppings += 1;
            toppings = toppings + "Mushroom ";
        }

//Task #2b: Set the initial cost of the pizza based upon the size. Hint: Use an if-statement (10inch = 10.99; 12inch = 12.99; 14inch = 14.99; 16inch = 16.99)

Task #2b Implementation

In this task, we have to set the initial cost of Pizza on the basis of Pizza sizes. If it is 10 inches, cost is 10.99, if it is 12 inches, cost is 12.99, if it is 14 inches, cost is 14.99, if it is 16 inches, cost is 16.99. So, we can do it using if-else statements and set the initial cost of Pizza like below:

       if(aPizzaOrder.getPizzaSize() == 10){
            cost = 10.99;
        }
        else if(aPizzaOrder.getPizzaSize() == 12){
            cost = 12.99;
        }
        else if(aPizzaOrder.getPizzaSize() == 14){
            cost = 14.99;
        }
        else if(aPizzaOrder.getPizzaSize() == 16){
            cost = 16.99;
        }

This completes all the required tasks. Let me know if you have any query or any difficulty in understanding it.

Thanks!
