InfoWorld·1yJDK 25: The new features in Java 25
JDK 25, the upcoming long-term support release for Java, is set to include a stable values API to improve application startup times and remove the deprecated 32-bit x86 port. Other potential features are in development, including those previewed in JDK 24, such as a key derivation function API and scoped values. JDK 25 is scheduled for release in September and will receive at least five years of premier-level support from Oracle.
Foojay.io·35wDesign Patterns Update to JDK25
JDK 25 introduces enhanced switch statements and pattern matching capabilities that modernize the implementation of classic design patterns. The release includes significant JEPs like Stream Gatherers, Unnamed Variables & Patterns, and Compact Source Files with Instance Main Methods. These features enable more functional programming approaches, improving code readability and maintainability while addressing complex implementation challenges across Creational, Structural, and Behavioral design patterns.
Awesome Java Newsletter·1yParallel processing with Virtual Threads - A comparative analysis
Explores the limitations of OS/platform threads and introduces virtual threads from Project Loom in JDK 21 as a solution. Provides a comparative analysis of virtual thread implementations in both JDK and Spring Core Reactor, highlighting use cases, performance metrics including processing time, memory footprint, and GC metrics. Concludes that JDK-based virtual threads are significantly faster for virtual thread implementations, whereas Spring Core Reactor performs better with platform threads.
Halodoc·37wMigrating from JDK 17 to JDK 21: An Overview and Practical Guide
A comprehensive guide covering the migration from JDK 17 to JDK 21, highlighting key benefits like Virtual Threads for improved concurrency and scalability. The article provides a step-by-step technical approach including environment setup, dependency updates, containerization, CI/CD pipeline modifications, and runtime optimization with Generational ZGC. Real-world results show 30% heap usage reduction, stabilized P99 latency, and over 10% infrastructure cost savings for I/O-bound services.
Inside Java·31wJDK 26: HTTP/3 Support – Inside.java
JDK 26 introduces HTTP/3 support to Java's HttpClient API, built on the QUIC protocol over UDP instead of TCP. Developers can enable HTTP/3 by setting it as the preferred version on HttpClient or HttpRequest instances. The implementation automatically downgrades to HTTP/2 or HTTP/1.1 if the server doesn't support HTTP/3. The HttpClient can discover HTTP/3 support through mechanisms like HTTP Alternative Services headers, allowing subsequent requests to use the preferred protocol. Early access builds are available for testing and feedback.
