Oracle Propels Development Forward with Java 22: A Comprehensive Overview

March 24, 2024 | by

Oracle, a leading technology company, has once again set the stage for innovation in software development with the highly anticipated release of Java 22. This latest iteration of the world’s most widely used programming language and development platform brings forth a host of enhancements aimed at elevating performance, bolstering stability, and fortifying security measures.

Java 22, also known as Oracle JDK 22, is a testament to Oracle’s unwavering commitment to empowering developers and organizations worldwide. Georges Saab, Senior Vice President of Oracle Java Platform and Chair of the OpenJDK Governing Board, expressed enthusiasm for the advancements introduced in Java 22, stating, “The new enhancements in Java 22 enable more developers to quickly and easily build and deliver feature-rich, scalable, and secure applications to help organizations across the globe grow their businesses.”

At the heart of Java 22 lie 12 JDK Enhancement Proposals (JEPs), meticulously crafted to enhance various facets of the Java language, APIs, and tools encompassed within the Java Development Kit (JDK). These enhancements span diverse functionalities, catering to the evolving needs of developers and organizations alike.

One of the cornerstones of Java 22 is integrating features from Project Amber, Project Loom, and Project Panama. Project Amber introduces several language enhancements, including Statements before super(…), Unnamed Variables and Patterns, String Templates, Implicitly Declared Classes, and Instance Main Methods. These additions simplify development workflows and enhance code readability and maintainability.

With its Structured Concurrency and Scoped Values features, Project Loom revolutionizes concurrent programming paradigms, offering developers enhanced error handling and observability capabilities. Similarly, Project Panama introduces the Foreign Function & Memory API and the Vector API, facilitating seamless interoperability with native code and delivering superior performance for vector computations.

Furthermore, Java 22 introduces significant updates to core libraries and tools, such as the Class-File API, Launch Multi-File Source-Code Programs, and Stream Gatherers. These enhancements empower developers with enhanced flexibility and productivity, simplifying complex tasks and boosting overall development efficiency.

Performance remains a focal point in Java 22, with the introduction of Region Pinning for G1. This feature reduces latency during garbage collection, enhancing system responsiveness and overall performance.

The release of Java 22 underscores Oracle’s steadfast commitment to driving innovation and fostering collaboration within the global Java community. By actively engaging with stakeholders through initiatives such as OpenJDK and the Java Community Process (JCP), Oracle continues to shape the future of Java, ensuring its relevance and longevity in an ever-evolving technological landscape.

“Java’s versatility and comprehensive toolset enable it to support the development of production-grade, mission-critical applications at scale, which positions it as a key enabling technology for innovative use cases such as generative AI,” remarked Arnal Dayaratna, Research Vice President of Software Development at IDC, highlighting the significance of Java’s continued evolution.

Mala Gupta, Java developer advocate at JetBrains, expressed her excitement about Java 22’s features designed to cater to developers of all skill levels. “Java is embracing a minimalist approach by continuing to reduce ceremonies around writing initial steps of code,” she said. “With constructor makeover (statements before super[…]), Java has proven again that it supports responsible innovation, and relaxing language constraints that existed from Java’s version 1.0 without breaking any existing code is very exciting.”

Tom Snyder, Oracle’s Vice President of Engineering for enterprise cloud-native Java, emphasized the tangible benefits of Java 22 for users of the Helidon web server. “The Helidon team recognized the value of virtual threads as soon as they were announced,” Snyder explained. “With Helidon 4, the team rewrote the Helidon web server to natively use virtual threads, which resulted in much better performance and increased developer productivity.”

As organizations navigate the complexities of digital transformation, Java remains a cornerstone of innovation. It enables businesses to harness the power of technology and drive growth. With Java 22, developers are empowered to unlock new possibilities, paving the way for a future of creativity, efficiency, and technological excellence.
