Java parameterized types are subject to type erasure so that generic types are lost at runtime. This means that, at runtime, a List<String> is indistinguishable from a List<Integer> or a List<Object>, without inspecting the elements in the list.

All this to say, you don't need to worry about the parameterized type at all. You can just create a List.
