How we write code was greatly influenced by Java 8. How we package the code and interact with it will be impacted by Java 9. In this presentations, we will learn about the major features of Java 9. We will start by discussing the current concerns and how the module system tries to alleviate those pains. We will learn about modules, how to define dependencies, and also how to work with existing jar files. Finally we will explore Java 9 REPL, the reasons to use it, and various features that can benefit the programmers.
