Upgrading From Java 17 To 21: All You Need To Know#video#java‑21 #migration

Java 21 is no LTS Version - Inside Java Newscast #52#video#java‑21

Java 21 - The Other Side - Inside Java Newscast #51#video#java‑21
OMG, how is there even more in JDK 21?! Scoped values preview, key encapsulation mechanism API, a new JFR command, and various API improvements. Generational Shenandoah is out, though, and it doesn't look good for the 32-bit Windows port either.

New (Sequenced) Collections In Java 21 - Inside Java Newscast #45#video#collections #java‑21
