Yes. It constructs a new ArrayList which is also a List.
List is an interface and can't be constructed directly. ArrayList is a class that implements the List interface. By coding this way, if you later decide that you would prefer to use a LinkedList instead of an ArrayList, you only have to change minimal code. The variable still remains a List and none of the uses of the variable change.
