Here we are trying to create Observable using create method where we get 15 different shapes. The create method provides a subscribe method where we are iterating each elements from list and emitting one by one. The emitted events are listened on DemoSubscriber.

For RxUtil.java class and DemoSubscriber and for full code you can refer git library : <a href="https://github.com/CODINGSAINT/rxJava-tutorial" rel="nofollow">https://github.com/CODINGSAINT/rxJava-tutorial</a>

Now once you run it you will get following output
