literal answer: Collections is a utility class for doing various things with collections. ArrayList is a class that implements the List interface, giving effectively a dynamic array

inferred answer: the same as the difference between a case of beer, and a beer. ArrayList is a part of the Collections "framework"

@OP: note that Collection is not the same as Collections. The first is an interface extended by the java.util.List interface. And the java.util.ArrayList class implements the java.util.List interface again.
