Known during development as Project Jigsaw, these tools let you break down your app and the core Java API into units known as modules. When you deliver an application you no longer have to deliver the entire core Java class library. Instead you only include what's needed. I'll demonstrate this with a new set of classes for making network requests. These tools were being developed during Java 9's development but at the time Java 9 was released, they were considered still to be in incubator status.
