Thank you all for your fantastic work. I’m particularly impressed by the ability of this presenter to enthusiastically describe obscure details of changes and fixes - this is quite a feat!

For future Release Notes please add a screenshot or descriptive line of text for every JEP/JDK point. It helps following and allows muted viewing (e.g. in the train).

P.S.: *Please* change the "when" in guard clauses! It's confusing to have a condition for something AFTER the guarded outcome. If you change "when" back to "&&" it reads as part of the same case condition *in front* of the case statement and makes sense again. I want to read left to right! Please consider it.

P.S.S.: The word "case" in switch could be stripped away and it would still make unambiguous sense.

I find it funny that there are still people that don't like the Oxford comma. It's the logical choice and he even made a joke about it haha.

When can we use the bracket-style index access with strings and maps...☹

Real charming changes, out of security and performance, most of it out of use for enterprise projects. It's more for small projects or libs that aint gonna change much, at least in my point of view for the time being, maybe in future we'll have much more updated code. I still see and work on implementations that are deprecated or just too antiquated. I hope for the new features like those being more present in courses, tutorials and books.

Java on UWP, consider both jvm launcher and and a runnable jar application wrapper

I love this channel, but the subject of this video is too complicated and to talk about it without proper illustration is a bad idea.
It will be better to show more code snippets or illustrations, just like N. Parlog does.

I have posted the new features in Java 22 with working code examples here

Why does Java release new versions when the world is already moving to Kotlin, and no one is interested in it. The company should stop, admit defeat, and give way to the promising languages Kotlin and Golang. It's a pointless waste of time; nobody starts new projects in this language anymore. Even on TIOBE, it will soon be overtaken by C#. Can someone explain to the creators that their language is no longer needed, they are late in its development, and now they are trying to catch up and convince everyone that Java is still relevant? Heh.

Problem with java is that its trying to adopt all the lastest goodies but also has to carry decades old baggage to remain backward compatible resulting in a mess of a language
For any new serious project rust is the way to go!!
I am done with java.

Can't you be "quiet" just for a couple of years? Too many cooks spoil the broth.
