Java 17 Deep Dive by José Paumard

The 'next LTS' is like Nessie! Everybody talks about it, but nobody knows anything about it!

The features released between Java 11 and Java 17 have brought a greater opportunity for developers to improve application development productivity as well and code expressiveness and readability. In this deep-dive session, you will discover all the recent Project Amber features added to the Java language such as Records (including Records serialization), Pattern Matching for `instanceof`, switch expression, sealed classes, and hidden classes. The main goal of the Amber Project is to bring Pattern Matching to the Java platform, which will impact both the language and the JDK APsI. You will discover record patterns, array patterns, as well as deconstruction patterns, through constructors, factory methods, and deconstructors.
