The release of the JDK 17 brings interesting features in the Java language: sealed types and pattern matching for switch (as a preview feature). Along with the introduction of records, the implementation of pattern matching in the Java language begins to take shape. The JDK 18 brings even more with Record pattern matching (as a preview feature). In this presentation we show you how leveraging these features can bring very clean solutions to improve the modularity of your application. You will see on real patterns how pattern matching can change the way you write Java code. You will also see what we can expect on this topic in the future. It is mostly a live coding presentation, with some slides when the code shown cannot be executed.

The features released between Java 11 and Java 18 have brought many opportunities for developers to improve application development productivity as well as code expressiveness and readability.In this hands-on 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. You will also have the ability to test some of the newer APIs introduced in the JDK (ex. UDS). In addition, this lab will also touch on some newer tools (ex. jwebserver) and features introduced recently in the JDK (ex. serialization filter).Attend this Hands-on Lab to understand what JDK 18 brings to developers, and make sure to bring your laptop!
