Hey Joe, if you copy paste these timestamps in the video description RU-vid will auto add sections to the video, could be helpful

Easily one of, if not THE best tutorial on Streams for Java 8. I still come back to this when I've not coded in a while after a hiatus. It's so good! Was confounded by the range of Streams functions when starting out in Java 8. Im absolutely zooming through them now and much more confident to create my own. Thank you so much, Joe!

@atrantech11 Месяц назад

This was infinitely helpful. I love how you gave so many examples. Thus, allowing me to understand and play around with these examples. Best stream tutorial and will come back to it later as refreshers.

@ashethebostonterrier4918 4 года назад

Very good explanation including using stream, array, map, collectors and lambda. Thanks. I have learned a lot. Very short implementation, but got lots done. I never would have thought using map, filter like in JS in Java. You can see how long I haven’t touched the Java. I need to prepare for interviews in their future. This helped me. Always nice learning something new.

@arthastfp 2 года назад

I'd like to point out something about example 7. You said it's better to first filter the stream, and then apply mappers. But you are first mapping the original dataset to a new lowercased dataset, therefore iterating through all the info, which in cases of massive amounts of data will slow down the application. The optimal solution is to first filter the stream, and then lowercase the remaining items. The same goes for example 8. This is just a nitpick on a great course overall, and I thank you for posting it!

@oggiai 2 года назад

Yes, you are right.

Except you, everybody starts their tutorial by saying 'Stream is the most difficult topic to learn and understand in Java'. But, you proved them wrong! Thanks a lot for sharing your knowledge with the world! Expect more tutorials especially on functional programming in Java in the same simple format. Cheers! :) :) :)
