RxJava is a Java VM implementation of Reactive Extensions: a library for composing asynchronous and event-based programs by using observable sequences.
It extends the observer pattern to support sequences of data/events and adds operators that allow you to compose sequences together declaratively while abstracting away concerns about things like low-level threading, synchronization, thread-safety and concurrent data structures.
This library provides some expressions, IF, Match like Scala. IF enables java if-statement to return a value as Scala if-expression. Match also enables java to use pattern-match expression.
