What's new in Java 9 ?

Question

Is learning java 9 worth the hassle? I've heard of JShell which can execute java code without any class or main function just like python. Is it as incredible as python or is it a gimmick?

^There ya go. Plenty of info on the changes.

For me personally, I haven't had a need to focus on Java 9 yet, but it's definitely worth catching up on the changes and learning them. From what I can tell, looks like mostly good changes.

As for if Java is a gimmick, no, it's not. As for saying Python and incredible in the same sentence, no, it's not. Python and Java isn't even something that I would be comparing together. If you're asking if you should focus on Java over Python, then my completely bias opinion is yes. :) In all fairness though, Python is capable in what it does, and even though it has a crappy syntax, it doesn't mean it's useless.
