    Post Make a constructor

    Hey guys, for this code I need to have a proper constructor and I dont know which part of the code to make as a constructor. I thought the prices and the size of the pizza I can make as a constructor but I dont know how to do it.

    Here is my code:

    import java.util.;
    public class Pizza {
    public static void main(String[] args)
    {
    final int NUMBER_CHOICES = 4;
    String[] Size = {"S", "M", "L", "X"};
    double[] size_prices = {6.99, 8.99, 12.50, 15.00};
    String chosenSize;
    double pizzaPrice = 0.00;
    boolean validChoice = false;
    Scanner inputDevice = new Scanner(System.in);
    System.out.print("Choose your pizza sizes - S, M, L, or X: ");
    chosenSize = inputDevice.nextLine();
    for(int s = 0; s < NUMBER_CHOICES; ++s)
    {
    if(chosenSize == null ? Size[s] == null : chosenSize.equals(Size[s]));
    {
    validChoice = true;
    pizzaPrice = size_prices[s];
    }
    }
    if(validChoice)
    System.out.println("The size f your pizza is " +
    chosenSize + " and total need to pay is $" + pizzaPrice);
    else
    System.out.println("Sorry - Wrong size! Please try again");
    }
    }

    split the code into sections

    public class Pizza {
        some common variables
     
        Pizza() {    }
     
        Pizza(String size) { }
     
        double sizeToPrice(String size) { }
     
        void sizeInput() {   }
     
        public static void main(String[] args) {
           Pizza p = new Pizza();       
        }
    }

    Take a look at the tutorial: https://docs.oracle.com/javase/tutor...structors.html
    Make a try. If there are error messages, copy the full text and paste it here.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
