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

[b]Description[/b]

Embark on an enlightening journey through the rapid evolution of the Java language with our comprehensive course, meticulously designed to keep you at the forefront of modern Java development.Key Focus Areas:1. Mastering Modern Java Language Features and Tools2. Enhancing Developer Productivity3. Leveraging Virtual Threads for Improved Application ScalabilityCourse Objectives:Gain a profound understanding of the evolving Java language and platform post Java 17. Explore a plethora of enhancements, innovations, and tools introduced from Java 18 to Java 21, delving into Language Features, Library Enhancements, Tools, Deprecations, and more, with a dedicated section for each Java release.Highlighted Topics:- Improving API Documentation- Exploring Simple Web Server- Mastering Character Encoding and UTF-8- Working with Sequenced Collections- Harnessing the Power of Virtual Threads and Structured Concurrency- Understanding how Virtual Thread work behind the scenes- Unpacking Pattern Matching for Switch- Record Patterns DecodedThis course is tailor-made for Java developers eager to master the latest language features and tools, enhance productivity, and leverage virtual threads for superior application scalability. While not a migration guide, it covers areas that can significantly impact migration scenarios.For any questions, I provide full support seven days a week, ensuring you have the assistance you need to maximize your learning experience.
