I'm currently working on a simple program that takes user input to create a gorcery list with prices and item names. It's not giving me any error codes when I run but rather nothing is appearing. I'll attach a photo below.

how do you want to take item if your itemNames has 0 elements so size is 0

[stable berry]

so should i keep it at a set amount or ask the user for the amount of items beforehand and set that to the size?

[wintry hill]

u can even do while true, and if user wants to finish shopping he should write for example finish.

if (item.equals("finish")) break;

[stable berry]

Would this work?

I've tried running and am now getting a seperate problem

[cunning osprey]

look up how to take in a Double

it should be scanner.nextDouble() you're calling scanner.next()

[stable berry]

Sorry for not updating the screenshot, I did notice that and fixed it earlier

write this code here, on chat

import java.util.Scanner;
import java.util.ArrayList;

public class TotalPrice{
   public static void main(String[] args) {
       Scanner inpt = new Scanner(System.in);
       
       ArrayList<String> itemNames = new ArrayList<String>();
       ArrayList<Double> itemPrices = new ArrayList<Double>();

       for (int i = 0; i < itemNames.size(); i++) {
           String item = inpt.nextLine();
           System.out.println("Please type in the name of the item you would like to purchase: ");
           itemNames.add(item); //itemNames.add....system.in
           Double price = inpt.nextBoolean();
           System.out.println("Please type in the price of the item: ");
           itemPrices.add(price);
           if (item.equals("finish")) break;
           else {
               System.out.println("Error, please retype.");
           }
           
                 }
       }

If Scanner#nextLine reads an empty line after calling a different Scanner#next method, take a look at this StackOverflow post.
