Can u tell me what u know about java language?

Answer 1

We can't talk here... Big Java is watching.

Answer 2

https://docs.oracle.com/en/java/

^That's best place to look. It has the full documentation on Java and will tell you everything you want to know about Java.

https://www.sololearn.com/Course/Java/

^SoloLearn provides a course also. I'd recommend taking it as well.

Do you have any specific questions about Java that I could help you with? I'm not sure it's plausible for me to tell you what I know about Java language since that's basically just teaching you Java from start to finish.
