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.
