Java Java Lists Java Lists Java Lists Quiz

Unsure what the quiz question is asking of me, any help appreciated

I'm doing the beginner Java track and have found myself stuck for the second time.

First question is asking to declare a list of rocks with most of the code already written.

So I started with

List<String> rocks = new ArrayList<>();

I've re-watched the video several times now and this exact syntax is used as far as I can tell with groceryLine instead of rocks. But it wont accept it here. I don't know what the question is looking for.

The instructions say to "Fill in the blank to declare the rocks variable as a List that contains Rock‍s", but this code creates a list that contains String‍s instead.

Note that "Rock" is an object class defined later in that same code.

Sounds like you nearly had it; but the name of the object class is "Rock", singular, and with a capital "R".

All the documentation I can find online and video all use some form of list<String> example =

I'm just more confused than before sorry.

Out of curiosity I tried List<Rocks> or list<rock> or list<object> but none of that works, but i figured that much.
