How do i store prices for food on a menu?

[airfrog19]

I'm having trouble implementing prices for my menu program. At the end of the loop it just prints out the food i ordered, but doesn't print out the prices. How do i do this ?

This is what i have: 

 

package project.pkg1;

import java.util.Scanner;

import java.text.DecimalFormat;

 

public class Project1 {

 

 

    public static void main(String[] args) {

     int choice = 0;

     boolean doneOrdering = false;

     String order;

     Scanner Keyboard = new Scanner(System.in);

     DecimalFormat moneyFormat = new DecimalFormat("$#,###.00");

     

     

     double num, GoodBurger = 0, GoodSalad = 0, Soda = 0, KidsMeal = 0;

     double GoodBurgers = 7.75;

     double GoodSalads = 7.00;

     double Sodas = 2.00;

     double KidsMeals = 3.00;

     double tax;

     double subtotal = 0, total;

     final double salestax = 0.875;

     

     

     System.out.println("Welcome to Good Burger!");

     System.out.println("=======================");

     System.out.println("Place your orders and type 'Finish' when you are done");

     System.out.println("--------------------------------------------------------");

    

    

     System.out.println("1. GoodBurger $7.75");

     System.out.println("2. GoodSalad $ 7.00");

     System.out.println("3. Soda $2.00");

     System.out.println("4. KidsMeal $3.00 \n");

     System.out.println("What would you like? \n");

    

     while(!doneOrdering){

         choice = Keyboard.nextInt();

         if( choice == 1){

             System.out.println("GoodBurger");

             subtotal = subtotal + GoodBurger;

         }

         else if( choice == 2){

             System.out.println("Good Salad");

             subtotal= subtotal + GoodSalad;

         }    

         else if( choice == 3){

             System.out.println("Soda");

             subtotal= subtotal + Soda;             

         } 

         else if( choice == 4){

             System.out.println("KidsMeal");

             subtotal = subtotal + KidsMeal;

         }

         else if( choice == 5){

             doneOrdering = true;

         }

         else{

             System.out.println("Invalid");

         }

          

     }

It doesn't print out the price,pretty obvious.

(+)You could try printing the price of each food when you chose it(if you want), I haven't done java in a long time but it should be like this : 

 

syso("<foodname> " + <foodpricevariable>);    <- syso is just a shortened form for System.out.printl in Eclipse , you need to write it full though.

 

 

Also change the subtotal thing to:

subtotal += GoodBurgers/GoodSalads/Sodas/KidsMeals ( the variable in which you store the price of a certain food type).

 

Then, at the end (choice == 5), also print the subtotal variable.

 

else if( choice == 5){

             doneOrdering = true;

             syso("Total : " + subtotal);

         }

It doesn't print out the price.Simply.

how do i do calculate the subtotal?

Read my updated post.

You're already calculating it.

Wait no...Time to update my first post again.

[airfrog19]

Read my updated post.

You're already calculating it.

So i need to create another variable for the price of each food?

And where would i put syso("<foodname> " + <foodpricevariable>); ? In the beginning?

You already have them :

 

     double GoodBurgers = 7.75;

     double GoodSalads = 7.00;

     double Sodas = 2.00;

     double KidsMeals = 3.00;

 

Just change

 

subtotal = subtotal + GoodBurger/GoodSalad/etc. ( not the doubles I've just listed)

to :

subtotal  = subtotal + GoodBurgers/GoodSalads/etc. ( the variables in which you store the price for each food)

 

Then print it at the end.(choice == 5)

Ok got it. Just one more question: Once i get get all the prices, i have to print out a receipt of what i ordered. Do you know how to do that. I know it has something to do with Arrays.

You're already printing the name of the food (and the price of it if you did as I said) each time you order it.

If you have, let's say, 2 burgers, and want to print : 2 x Burgers : <price>

Then you need to change it a little bit.Create counter(s) for the amount of times you order each type of  food, remove all the printing in the first 4 choices.

You already have counters for the amount of times you order a food :

 

     double GoodBurger = 0, GoodSalad = 0, Soda = 0, KidsMeal = 0;   <-These are counters

 

Change each of the first 4 choices into this :

 

if (choice==<whatever>) {

<counter>++;

subtotal += <foodpricevariable>;

}

 

Then, at choice == 5 :

 

if(<counter>) syso(<counter> + " x <food name> : " + <counter> * <foodpricevariable>)

 

Then apply it for each of the food types.

Then at the end print the total, like you're already doing.
