ArrayList with User Input

[eikkaj]

I created something using an array previously that basically added ShoppingItems to a ShoppingList that would be sorted by priority and then purchased using a "budget".

I am trying to change this from an array to an arraylist but am having trouble.

First, I need to create the arraylist and get the input to create the shoppingitems, which include a bunch of different input (priority, cost, name, quantity).

For the array, I had this:

 public static void main(String[] args)
    {
        ShoppingList go = new ShoppingList();
                go.getElement();
                go.Sort();
        System.out.println("hello");
        go.displayResults();
    }
 

And then the getElement method was this:

public void getElement(){
        System.out.println("You can add seven items to purchase when prompted ");
    shoppingList = new ShoppingItem[numItems]; //creation of new array object
    for (int i = 0; i<= numItems - 1; i++)
        {
            shoppingList[i] = new ShoppingItem(); //shopping item objects created
            System.out.println("Enter data for the shopping item " + i);
            shoppingList[i].readInput();
            System.out.println();
        }
   }

So with my arraylist, I'm thinking it should be something like this?

public static void main(String[] args) 
    {
        ArrayList<ShoppingItem>ShoppingList = new   ArrayList<ShoppingItem>();
        ShoppingList.add(getElement());
