Java 19 and beyond | What's new in Java 19?

Java 19 is the next intermediate release on the way towards Java 21, the next long-term supported release of Java. The easiest way to prepare for Java 21 is to digest the big changes in little parts. I already made a video on Java 19 parallelism features (Project Loom, Structured Concurrency, and Virtual Threads) - see the link below. This video covers three other major features of Java 19, that come from project Amber and project Panama.
Within this video, I'll cover why it's good to keep up with what's new in Java, and will explain what do Pattern Matching, Record Patterns, and Foreign Function And Memory API bring to the table - with code examples. I will cover the use cases, current state, and what to expect.

Thanks by your video.
I love Records too.

Hi, thank you! Yeah, it's a small improvement, granted, but I use them every day, feel good about it, and small things tend to add up quickly. :)

[@lovetyagi5266]

Please make video on Java Concurrency and Non-blocking-IO

[@DevXplaining]

Thank you! Yes, that sounds like a good idea.

Less boilerplate for Java is always welcome lol

[@DevXplaining]

Ohyeah! Haha :)
