Java 22 and 23 are full of helpful little additions and exciting previews: from unnamed patterns to module imports, from the foreign-function and memory API to stream gatherers and the class-file API, from a simpler main to launching multi-source-file programs, from Markdown in JavaDoc to improved garbage collection. There are plenty of features in the language, API, and runtime to discuss - whether new, improved, or finalized. This deep dives goes over all of them.
