Erik was correct. You can create an empty list by leaving it blank and adding in values later.
If you already have some sort of Collections that contains data, you can input that into the parenthesis to fill your new list.

It really reminds me of C# generics
List<int> numbers =new List<int>();
I don't know Java. But my hunch is it inializes a list of strings
