Hey Joe, if you copy paste these timestamps in the video description KZread 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!
This is actually better than some of the paid courses on pluralsight. Keep up the execelent work!!

Spot on. This video...the instructor...excellent.
Fantastic. Crystal clear and no nonsense class.
Only time I've seen Java 8 streams explained clearly online. Thank you Joe
Great video! Loving streams already!
excellent tutorial...exactly what is needed for java developers upgrading to functional programming.
Simple. Easy to follow. Straight to the point. Basically the most descriptive video I have seen so far on Java streams. Thank you so much.
Simple, rich and elegant. Love this tutorial!
Intensive and clear, great value for each minute watched on this video
Great great!!!! Excellent explanation... thank you very much. It was exactly what i need.
Awesome! I wasn't comfortable with streams before, but after this video I immediately changed three for loops of my program to streams. Looks so much nicer and is not so tedious to code. Thanks!

Thank you for the very good tutorial. It's well explained and straight forward, exactly what I was looking for!
Excellent work Joe, thank you for explaining this with easy to understand examples.
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.
I haven't touched Java in a while and now it looks like magic to me. Your explanation though made it understandable, thank so much!
This is such a mind blowing feature, thank you very much for explaining in such detail!
this type of tutorial covers more topics and condition than others typing n explaining the course
A one-stop place for Streams. Excellent video. Great Job Joe !
REALLY NICE EXAMPLES explaining various usage options of Streams API. Thank you !!!
Just commenting to say thanks, Joe. This was a VERY helpful tutorial. THANK YOU!
love how it was simply straight to the point!
I got a hands-on on streams a bit more than before. Thanks for making this video Joe.
Wonderful explanation Joe. Thanks for the tutorial!
This is the best video to explain Java collection I've seen in KZread. Thank you!
A great video - small and simple examples that get the message across clearly. Thank you.
Hey. I would like to emphasize that this tutorial for Java 8 streams is really great. I've been looking through internet for some good explanation. Found many sites or tutorials, but this one is best quality step-by-step. I found everything that I needed from the beginning. Thanks
Great video, Joe! Thanks for the efforts and continue shooting videos like this please.
This makes map very easy to understand. God all this time I thought it had something to do with hashmaps, KV pairs etc...this really helps, ty!
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.
Great explanation. Really helped understanding the concepts. Thanks for sharing the knowledge!
Excellent. Best tutorial on java stream came across.
The Best Explaination i have ever seen about java streams. Thank You So much.
Really good tutorial, I have used streams but I wasn't sure of some concepts, now it's clear, thanks a lot!
This is one of the most useful techniques in Java Ive ever seen.
I have watched several videos on this, and this was the best! Helped me understand the concept.
Thank you so much Joe, my lecturer can't explain this simple feature in 2 hours, you did it in 20mins. seriously You should teach in our uni.

Thank you so much. This is the best explanation I have seen so far with great examples.
No nonsense explanation. Thank you very much.
Wow Java is actually much better when it comes to file handling than expected! Great video, thanks!!
Joe James is a great teacher and a great mentor,I must affirm . How I wish have known him in my early days of programming.
Thank you Joe for this excellent tutorial which is probably better than most of the ones out there.
Excellent!! Clear & Concise . Thanks so much.

Great presentation ... plain and simple ... that is what we want, almost always.
Very good collection of Stream examples, Learning about Files and IntSummaryStatistics was a bonus.
Wow great explanation, thanks Joe!
Very informative with very clear and concise explanation.

Great explanation on Java Streams. Cleared the basic concepts of using Stream API.
Very nice Tutorial. Thanks a lot, Joe
Hey dude, thanks so much for making this video. I never knew the Stream API was a thing, and thought it was hard. After you gave those examples and all, I know understand it. This seems to be a really useful API indeed and can't wait to use it, not only that, but it seems much easier.
THIS IS THE VIDEO I WAS LOOKING FOR. Thank you.
Great , concise and rich!
Superb video, i have seen many videos but didn’t find any other video giving this much of examples
Fantastic. Although it took my 40 min to write out, run, and understand the code, it was well worth it
best video on Stream.....thank you so much
THANK YOU I MISSED "x.contains()" NOW I KNOW HOW TO FILTER STRING
Excellent video, many thanks!
Finally I am understanding this topic! Thank you very much
This is short precise and gives all the valuable information. Thank You so much for the nice video!
you are a smart cookie. Thank you for this refresher
Great lesson! Thank you very much!
