5 ways to use the static keyword in Java

I just had an interview where one of the questions was something like "Describe 5 ways to use the static keyword in Java." I could only think of 2 on the spot, and afterwards I found 2 more. What is the 5th?

  1. Declaring a field belonging to a class as opposed to an instance of the class.
  2. Declaring a method that can be called on a class as opposed to an instance.
  3. Declaring a nested class as static
  4. Defining a static class initializer.
  5. ???

Would declaring a static interface be considered a class in this instance? If not then there's another use.

Constants - static final (which is really the same as #1, but could be consider a separate usage)
