Welcome to the Java-9-Discovery Meetup.

As Java 8 was hailed as a great release for developers, due to the introduction of Streams, Lambda expressions, Method references, Completable future, Optionals and many others that helped us with write code in functional style. It was really a new way to think how we write code.I agree when Dr. Venkat Subramaniam Says Java 9 modularity doe nothing for the way we write code but is all for packaging / deploying the code.

Of course there are things that affect us developers and some of those are the ones that we are here to talk about, But the Project Jigsaw as it is called actually affects how we package and hence at the end deploy code. We will have a look at this in once we look at the Java 9 Modularization.
