The JEP Café and the Inside Java Newscast were the best ideas for Java since introducing Lambdas.

Thanks. Always a pleasure enjoying my coffee here.

[unbekannter_Nutzer]

Thanks, very informative. :)
Where do I find the fancy regular expressions from @12:20?
(or: What would be reasonable?)
Thanks.

what a wonderful, informative, and insightful video, thank you 😊

[ubaidrehman]

Nice presentation. The way you showed the JDK code increased my interest. I am going to do the same in my local. Thanks

Great video! Looking forward to the Structured Concurrency video.

I just discovered JEP Café. Omg... subscribed.

[whatValuesDoYouLiveBy]

Un grand merci! I would love to see more about how Java uses virtual threads to make async programming easier! 🥰

[MakeItStik]

As usual another great video by Mr. Paumard. Please make such videos more frequently.

[sadiulhakim]

Look at this amazing community, Java Community.

[VisruthCV]

Very informative examples, great presentation. Keep it up. Thanks for publishing!
Java is awesome 👍

[anhle]

Thank you, it's great video and I want to see Structure Concurrency next time too.

[AleksandarT]

Great video, it would be good if you can make more videos on these topics!

[feryadialoi]

finally JEP cafe with some code hands on🔥

[anty_]

This was just amazing. Looking forward to more of such talks.

[aum]

Reminds me of Erlang/Elixir. Great to see something similar in Java.

[seafront]

Nice video, looking forward to next one

[johnbrinnand]

Great explanation of Virtual Threads. If we could get more of the same with links to the code - that would be great. Thanks for a great presentation

[triettruong]

I love simple explanation on complex topics like this. Thank you for your time and efforts to provide understandable piece of knowledge! Can't wait for the next topic. Btw, I was also drinking coffee while watching this.

The yield-resume sounds like a safe version of stopping and resuming a thread, pretty cool
