Create and objects in ArrayList when mouse is pressed

[Chrisir]

@alex119

why do I have to check if the size is greater than 0, to use the object inside the ArrayList

When the list is empty, its size() is = 0.

it’s empty. Nada. Nothing. Niente.

So when you say bulletList.get(0) you try to access an element that isn’t there (number 0).

This gives you an error.

(apparently it works when you pressed the mouse because then the ArrayList has an entry or a few entries)

TRY

println(bulletList.size());
