Java 23 has been released, bringing several new features and improvements to the popular programming language. The release aims to modernize Java and make it more competitive with other languages like Python and Rust. One of the key updates in Java 23 is the Z Garbage Collector (ZGC) generational mode, which is now enabled by default.
This enhancement optimizes garbage collection processes, reducing overhead and improving application performance. Developers can now benefit from these improvements without the need for extensive manual configuration. Java 23 also introduces language feature previews, performance and runtime updates, enhanced scalability and resource efficiency, pattern matching for switch, and the Foreign Function & Memory API.
These features are designed to accelerate feature delivery, reduce technical debt, and allow seamless integration with native libraries.
Java 23 improvements streamline development
Analysts have praised the release of Java 23, noting its continued modernization while maintaining backward compatibility.
Andrew Cornwall from Forrester remarked, “Oracle is evolving Java into a modern programming language…”
IDC analyst Arnal Dayaratna highlighted three key takeaways: improved scalability with virtual threads, faster and more maintainable code with pattern matching for switch, and seamless integration with native libraries via the Foreign Function & Memory API. James Labocki from Red Hat emphasized the significance of Java 23’s focus on concurrent programming and streamlining the developer experience, stating that these updates drive toward making Java more accessible and powerful for developers. Java’s new features are positioned to compete with Python and Rust, which are often viewed as more modern or easier to use.
Chad Arimura from Oracle stressed the importance of these updates in making Java more competitive. Georges Saab from Oracle discussed the importance of the new generational mode in the Z Garbage Collector, explaining that it now makes ZGC more versatile and suitable for a wider range of applications. The release of Java 23 marks a significant step in the ongoing evolution of the language, solidifying its position as a robust and modern choice for enterprise applications.
