On top of page 576 of K&B SCJP 6 it says that the Arrays.sort() method is overriden in the same way Collections.sort() method is.
What? Arrays and Collections extend from Object class. Object class doesn't have a sort() method, so... Where is the override? Which method did Arrays.sort() or Collections.sort() overrode? I just don't see how those two methods are overriden in any way. What am I missing here?
My guess is that is a edition mistake, please any comment on the topic would be greatly appreciated. I have been pondering this for days.
