finalize is deprecated

[seyedjafariy]

Since Java9 this method has been deprecated. Even before java9 using finalize was always disouraged.

I really think it should be mentioned in the docs

Yes, you right,
but the main reason I added this question was to know whether he or she didn't any researches about what are the main Object's methods and how they work or not.
it will be mentioned and fixed,
