How can you create objects in a loop and save its memory to a different location?

how can I create numerous objects inside a loop and store each cycle inside a different location of memory? For example, I am writing a test program for my shopping bag program, and I would like to add Candy and Milk to my shopping bag. When I type these objects in for the user input, and print it out, it only prints out the last object. Which is milk. I have thought about using array list, but I do not know how to add the object name,price,quantity to that array list of an object.

Here is my code if you would prefer to look at it:

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


public class TestDriver 
{

    public static void main (String[]args)
    {
        ArrayList<ShoppingBag>list= new ArrayList<ShoppingBag>();
        Scanner sc = new Scanner(System.in);
        Boolean answer=true;

        ShoppingBag shop= new ShoppingBag(6);

        while(answer==true)
        {

        System.out.println("Enter the name of the items(Enter None to stop): ");
        String name=sc.next();
            if(name.equalsIgnoreCase("none"))
                {
                    answer=false;
                }
            else
                {
                shop.setName(name);
                System.out.println("Enter count: ");
                int count=sc.nextInt();
                shop.setNumberOfItems(count);
                System.out.println("Enter cost(unit price): ");
                float subTotal= sc.nextFloat();
                shop.setSubtotal(subTotal); 

                }

        }
        System.out.println(shop.toString());






    }
