Lombok is a tool that makes it possible to write classes in Java the way it is supposed to. It reduces a lot of the boilerplate code required that many modern languages already have built-in support for, such as Golang and Kotlin. Lombok supports the traditional OOP class structure with getters and setters, but my favorite part is the Lombok Builder which enables us to write immutable classes with almost no code required at all. In this article, we are going to explore that and hopefully, you will be convinced and start using it yourself.
Java 9 comes with support for a feature that has been requested a lot, Reactive Streams. However, the idea of Reactive Streams isn’t anything new. It has existed in external libraries such as (and probably most popular) RxJava. But it’s nice to finally see support from it in an official Java release.
