Java books

Hi gurus,
could you please share authors' name of Core Java books? I have worked on java for more than three years so I have knowledge on pretty much everything; however, I do not know things by name. For example I used polymorphorism or inheritance while doing code but do not know their identity by name and other behaviors/types. Well I tried my hands on Sun website but hope book would be more particular to acquire holistic view.

It would be nice if you kindly provide be author names of good books on Core Java.

Thanks indeed.
John
