What’s New in JDK 22: Embracing Functional Programming
Java’s latest release, JDK 22, marks a significant milestone in its evolution. This version introduces a slew of features and enhancements, pushing Java closer to functional programming paradigms and aligning it with languages like Kotlin. In this blog post, we’ll dive deep into JDK 22’s offerings, exploring the importance of each new feature, providing use cases, and offering sample implementations. Additionally, we’ll discuss how Java is adopting more functional programming jargon, bridging the gap with Kotlin and other modern languages.
New Features in JDK 22
1. Project Loom: Lightweight Threads
Importance: Project Loom introduces virtual threads (also known as lightweight threads) to Java, making concurrency management more efficient and straightforward. Traditional threads, while powerful, are expensive in terms of memory and context-switching overhead. Virtual threads aim to alleviate these costs, allowing developers to write simpler, more scalable concurrent code.
Use Case: An application that needs to handle thousands of concurrent client connections can benefit significantly from virtual threads. Instead of dedicating a heavy OS thread per connection, which is resource-intensive, an application can leverage virtual threads to…
