java - How can Arrays.asList return an instantiated List?

Question

Arrays.asList returns a typed List. But List is an interface so how can it be instantiated? If try and instantiated a typed List I get an error saying it is not possible.

Edit

Nevermind I see what's going on, just got confused by the docs for a moment.

It's an Arrays.ArrayList which shouldn't be confused with java.util.ArrayList. It is a wrapper for the array which means any changes you make, alter the original array, and you can't add or remove entries. Often it is used in combination with ArrayList like

 List<String> words = new ArrayList<>(Arrays.asList("Hello", "There", "World"));
