The only things that can be overridden are non-private, non-final, instance methods.
Nothing static.
Nothing final.
Nothing private.
No variables, only methods.
Note, however, that some of the "NOs" above can be hidden or shadowed.
If you want a more detailed answer, you'll have to ask a more detailed question--for example, what you think overriding means, why you're specifically asking about final and static, etc.
