RxJava

Since its inception in 2012, RxJava has slowly gained in popularity for enabling reactive programming on Android. It is now deemed as the go-to and leading reactive library. Many companies have adopted the reactive way of programming, including Google, with its release of Android Architecture Components, which has many reactive elements in its design.

In this course, you will learn the fundamental principles of RxJava which will serve as a foundation for experienced Android developers who are new to the library and want to start integrating it into their apps.

Reactive Programming with RxJava

## Problem

Modify the following `Observable` chain so that each print statement is executed on a separate thread.

```java
Observable.just(1, 2, 3)
       .doOnNext(value -> System.out.println(Thread.currentThread().getName() + " : " + value));
```
