Strings Just Got Faster
2025-05-01 15:00:03
In JDK 25, we improved the performance of the class String in such a way that the String::hashCode function is mostly constant foldable. For example, if you use Strings as keys in a static unmodifiable Map, you will likely see significant performance improvements.

How Can Machine Learning Assist to Improve JVM Performance
2025-03-10 14:00:02
Many developers are either unaware of or prefer not to use JVM flags when running their Java applications, especially those requiring complex numerical inputs, such as memory-related flags. Despite the abundance of these flags, tuning even just one or two can significantly enhance application performance, which is critical in performance-sensitive scenarios.

Java 24 - Better Language, Better APIs, Better Runtime
2025-03-01 14:00:03
Java 21 was an explosive release, but 22 to 24 are no slouches either: from unnamed patterns to module imports, from the foreign-function and memory API to stream gatherers and the class-file API, from a simpler main to launching multi-source-file programs, from Markdown in JavaDoc to improved garbage collection.

Valhalla - Java’s Epic Refactor
2024-12-20 14:00:02
Project Valhalla wants to heal the rift in Java’s type system between classes and primitives by introducing value classes, which “code like a class, work like an int” and offer a flat and dense memory layout.
Java’s epic refactor, as it has been dubbed, has been going on for 10 years but is now entering the home stretch.
During Devoxx 2024, Java Language Architect Brian Goetz gave a complete update and explained the proposed solution: value classes, null-restricted types, beefed up definite assignment analysis, and strict initialization.
