Don't forget that a deprecated method isn't replaced by a drop-in replacement:
if such a replacement is possible, you'd merely scrape out the old code and
drop in the new. No deprecation needed. A good example would be upgrading a
sort() method from the bubble sort to the quicksort algorithm.
Deprecated methods tend to have a revised API, i.e. returning a Collection or a
List instead of an array, so you'd want to deprecate the older method as an
indication that Java now provides better ways of handling data passed to or
from the method, i.e. if our sort() method now returns a List or Collection
instead of Object[].

Yes, they would and have deprecated their own methods, usually for the sort of
reasons I've just used as examples.
