Thanks for sharing this. It was good to hear about JavaOne returning! I had a co-worker that had a JavaOne vending machine ring.

Automatic module inpirts and implicit declared clases and isntance main methods are a little revolution to java, i am conviced this will make the language much more appealing for beginners!

[satturramesh]

Thanks for sharing the video, incredible changes in java

[brianskarup]

Nice to hear about JavaOne. I hope you will go back to 4 days of content like you did when JavaOne were in San Francisco instead of only 3 days like you did in Las Vegas.

[janbodnar]

The improvements for small Java are awesome! I wonder if there is a plan to work with external JARs like in Groovy.

[kotlinsky.]

Any chance for rust-like traits? (Implement interface for existing type from third party .jar library as example)

long live JAVA, i miss the old java applet so simple

You have the timestamps wrong. The hours are missing :)

[julianjupiter]

When will the work on Concise Method Bodies resume?

[donaldmiller]

I would like to see the code for the announce function. Why does it return a char[] and not a String?

[jpmottin]

I would say the show wasn’t enough prepared… but thanks anyway for the effort ❤ Long Live to Java !

Don't remove the Unsafe class. It's crucial in many libraries and very convenient to use with great performance

Now AI software Engineers are here what do we do as Java Software Engineers ??
