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.
