Thinking Beyond Java 17: Advancing To Java 21 & Beyond

Java 18 to Java 21: Navigate new language features, collection framework changes, master virtual threads and a lot more

[b]What you'll learn[/b]

Starting from Java 18, navigate through every release up to Java 21

New Language Features

Virtual Threads

Structured Concurrency

Make well-informed decisions about moving beyond Java 17

Tools and performance related improvements

[b]Requirements[/b]

A computer with the latest JDK(21) and an IDE

Programming experience ideally with Java 17 but 11 will also do (Some code examples in the last section reference Records, Pattern Matching)

To fully grasp the topic of Virtual Threads, a basic understanding of multithreading concepts, including Executors, is recommended
