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!!

[siphesihlesithungu]

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.

[Nothoughtinvolved]

Only time I've seen Java 8 streams explained clearly online. Thank you Joe

[avinpaladugu]

Fantastic. Crystal clear and no nonsense class.

[DerSpudi]

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!

[punyabrotad]

excellent tutorial...exactly what is needed for java developers upgrading to functional programming.

[atrantech]

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.

[sgtdutra]

Great great!!!! Excellent explanation... thank you very much. It was exactly what i need.

[tobyzhan]

Simple, rich and elegant. Love this tutorial!

[apfelll]

Thank you for the very good tutorial. It's well explained and straight forward, exactly what I was looking for!

[gongjiaji]

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.

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

[nabinrai]

this type of tutorial covers more topics and condition than others typing n explaining the course

[netindu]

A one-stop place for Streams. Excellent video. Great Job Joe !

Intensive and clear, great value for each minute watched on this video

[Romanov]

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!

[rkulk]

Excellent work Joe, thank you for explaining this with easy to understand examples.

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!
