It's not necessary but beneficial. Not only because it documents 
something, but also because your IDE checks that and in case you're 
changing some interface of a parent class you'll get an error message 
for the classes that now claim to override something, but don't (because 
you've changed theparents method's signature). Since this kind of 
refactoring-failure can easily lead to a non apparent error, it's good 
to check that.

Kind regards,
