This project is for :
- who is migrating to RxJava 2
- or just started with RxJava.
Just Build the project and start learning RxJava by examples.
RxJava 2.0 has been completely rewritten from scratch on top of the Reactive-Streams specification. The specification itself has evolved out of RxJava 1.x and provides a common baseline for reactive systems and libraries.
Because Reactive-Streams has a different architecture, it mandates changes to some well known RxJava types.
Migration From RxJava 1.0 to RxJava 2.0
To allow having RxJava 1 and RxJava 2 side-by-side, RxJava 2 is under the maven coordinates io.reactivex.rxjava2:rxjava:2.x.y and classes are accessible below io.reactivex.
Users switching from 1.x to 2.x have to re-organize their imports, but carefully.
Using RxJava 2.0 Library in your application
Add this in your build.gradle
If you are using RxAndroid also, then add the following

Map-> transform the items emitted by an Observable by applying a function to each item
Zip-> combine the emissions of multiple Observables together via a specified function and emit single items for each combination based on the results of this function
Filter-> emit only those items from an Observable that pass a predicate test
FlatMap-> transform the items emitted by an Observable into Observables, then flatten the emissions from those into a single Observable
Take-> emit only the first n items emitted by an Observable
Reduce-> apply a function to each item emitted by an Observable, sequentially, and emit the final value
Skip-> suppress the first n items emitted by an Observable
Buffer-> periodically gather items emitted by an Observable into bundles and emit these bundles rather than emitting the items one at a time
Concat-> emit the emissions from two or more Observables without interleaving them
Replay-> ensure that all observers see the same sequence of emitted items, even if they subscribe after the Observable has begun emitting items
Merge-> combine multiple Observables into one by merging their emissions
SwitchMap-> transform the items emitted by an Observable into Observables, and mirror those items emitted by the most-recently transformed Observable
