Java Reference

Question

Hi, I was wondering what reference site or doc can we use for Java.
When I´m Using Javascript I usually go to W3C but the information they have on Java is limited.
Any tip?

Answer 1

It is a german site but the links to the documentations are all in english:
https://javabeginners.de/docs.php

Answer 2

By the way:
Google " documentation of java api (+ version number)" gives a lot of results
