Oracle Releases Java 19

New launch delivers seven JDK Enhancement Proposals to extend developer productiveness, enhance the Java language, and improve the platform’s efficiency, stability, and safety

Java 19’s key capabilities to be showcased at JavaOne 2022 in Las Vegas on October 17-20

AUSTIN, Texas, Sept. 20, 2022 /PRNewswire/ — Oracle at this time introduced the supply of Java 19, the most recent model of the world’s primary programming language and improvement platform. Java 19 (Oracle JDK 19) delivers hundreds of efficiency, stability, and safety enhancements, together with enhancements to the platform that can assist builders enhance productiveness and drive business-wide innovation. Oracle will showcase the most recent capabilities in Java 19 at JavaOne 2022, happening October 17-20 in Las Vegas, and through a keynote broadcast airing on dev.java/ at 9:00 a.m. PT on Tuesday, September 20.

“Our ongoing collaboration with the developer group is the lifeblood of Java. Because the steward of Java, Oracle is steadfastly dedicated to offering builders and enterprises with the most recent instruments to assist them create modern apps and providers,” mentioned Georges Saab, senior vp of improvement, Java Platform and Chair, OpenJDK Governing Board, Oracle. “The highly effective new enhancements in Java 19 are a testomony to the monumental work throughout the worldwide Java group.”

The newest Java Improvement Equipment (JDK) gives updates and enhancements with seven JDK Enhancement Proposals (JEPs). Most of those updates are to be delivered as follow-up preview options enhancing on performance launched in earlier releases.

JDK 19 delivers language Enhancements from OpenJDK undertaking Amber (Document Patterns and Sample Matching for Change); library enhancements to interoperate with non-Java Code (Overseas Operate and Reminiscence API) and to leverage vector directions (Vector API) from OpenJDK undertaking Panama; and the primary previews for Venture Loom (Digital Threads and Structured Concurrency), which is able to drastically scale back the trouble required to write down and preserve high-throughput, concurrent purposes in Java.

“Java builders are more and more looking for instruments to assist them effectively construct extremely practical purposes for deployment within the cloud, on-premises, and in hybrid environments,” mentioned Arnal Dayaratna, analysis vp, software program improvement, IDC. “The enhancements in Java 19 ship on these necessities and illustrate how the Java ecosystem is well-positioned to satisfy the present and future wants of builders and enterprises.”

Oracle delivers new Java Characteristic releases each six months through a predictable launch schedule. This cadence gives a gentle stream of improvements whereas delivering steady enhancements to the platform’s efficiency, stability, and safety, serving to enhance Java’s pervasiveness throughout organizations and industries of all sizes.

Probably the most important updates delivered in Java 19 are:

Updates and Enhancements to the Language

JEP 405: Document Patterns (Preview): Allows customers to nest report patterns and sort patterns to create a strong, declarative, and composable type of information navigation and processing. This extends sample matching to permit for extra subtle and composable information queries.
JEP 427: Sample Matching for Change (Third Preview): Allows sample matching for change expressions and statements by allowing an expression to be examined towards a lot of patterns. This permits customers to specific complicated data-oriented queries concisely and safely.

Library Instruments

JEP 424: Overseas Operate and Reminiscence API (Preview): Allows Java packages to extra simply interoperate with code and information exterior of the Java runtime. By effectively invoking overseas capabilities (i.e., code exterior the Java Digital Machine [JVM]), and by safely accessing overseas reminiscence (i.e., reminiscence not managed by the JVM), this API permits Java packages to name native libraries and course of native information through a pure Java improvement mannequin. This leads to elevated ease-of-use, efficiency, flexibility, and security.
JEP 426: Vector API (Fourth Incubator): Allows superior efficiency in comparison with equal scalar computations by expressing vector computations that reliably compile at runtime to vector directions on supported CPU architectures.

Ports

Venture Loom Preview/Incubator Options

JEP 425: Digital Threads (Preview): Dramatically reduces the trouble of writing, sustaining, and observing high-throughput concurrent purposes by introducing light-weight digital threads to the Java Platform. Utilizing digital threads permits builders to simply troubleshoot, debug, and profile concurrent purposes with present JDK instruments and strategies.
JEP 428: Structured Concurrency (Incubator): Streamlines error dealing with and cancellation, improves reliability, and enhances observability by simplifying multithreaded programming and treating a number of duties operating in numerous threads as a single unit of labor.

Driving Java Innovation within the Cloud

The Java 19 launch is the results of intensive collaboration between Oracle engineers and different members of the worldwide Java developer group through the OpenJDK Project and the Java Neighborhood Course of (JCP). Along with new enhancements, Java 19 is supported by Java Management Service – an Oracle Cloud Infrastructure (OCI) native service – that gives a single pane of glass to assist organizations handle Java runtimes and purposes on-premises or on any cloud.

Supporting Java Clients

The Oracle Java SE Subscription is a pay-as-you-go providing that gives prospects with best-in-class assist, entitlement to GraalVM Enterprise, entry to the Java Administration Service, and the flexibleness to improve on the tempo of their companies. This helps IT organizations handle complexity, comprise prices, and mitigate safety dangers. As well as, Java SE and GraalVM Enterprise are provided freed from cost on OCI, enabling builders to construct and deploy purposes that run quicker, higher, and with unbeatable cost-performance on Oracle Cloud.

Underscoring Java’s recognition with the worldwide developer group, Oracle is proud to acknowledge the one millionth accomplished Java certification. Java certifications assist builders stand out as Java specialists and lift their profiles with enterprises looking for to draw extremely expert Java professionals.
