How to use RxJava Interval Operator

Question

I\'m learning about RxJava operator, and I found these code below did not print anything:

public static void main(String[] args) {

    Observable
    .inter         


        

Answer 1

Put Thread.sleep(1000000) after the subscribe and you will see it working. Observable.interval operates by default on Schedulers.computation() so your stream is being run on a thread other than the main thread.
