One more explanation for why modifying item in doOnNext() method didn't reflect in subscription, the reason is doOnNext accepts Consumer instance, and by definition, Consumer interface is : A functional interface (callback) that accepts a single value and doesn't emit anything, so doOnNext() is just observing the items being emitted and nothing else.

Hi, Could you make a video on onErrorResumeNext, and if I don't need to break the loop from observable and have to add exceptions in a list, how can I write the code. Thanks in advance
