On August 11 and August 25, respectively, there may be prospective releases of JDK 19, which will be made available on September 20. We entered the initial ramp-down phase last month.
The Java Development Kit 19, which is slated to go on sale in September of this year, is currently in its second ramp-down phase and is completely operational. The release of seven features is planned, including support for the open-source Linux / RISC-V instruction set architecture, recording patterns, previews of external functions, and storage APIs (ISA).
Other proposed additions, such as universal generics and value objects, must wait for a new platform iteration at this final stage of the standard Java release process. JDK 18 was released on March 22nd, and JDK 19 will follow. The typical Java release cycle lasts six months.
On August 11 and August 25, respectively, there may be prospective releases of JDK 19, which will be made available on September 20. We entered the initial ramp-down phase last month. JDK 19’s features include:
Foreign function and memory API
An introduction of APIs that enable Java programmes to communicate with code and data outside the Java runtime, including a glimpse of external functions and storage APIs. The Foreign Storage Access API and the Foreign Linker API, the two earlier incubation APIs, are combined to form the Foreign Function and Storage API. Earlier incubated in JDK 17 and re-incubated in JDK 18, external functions and memory APIs.
Structured concurrency
Through the Structured Concurrency API, Structured Concurrency aims to make multithreaded development easier during the incubator stage. This parallel processing streamlines error management and cancellation by treating many tasks that are being performed in various threads as a single unit of work. increases observability and dependability.
Pattern matching
The third sample of pattern matching between switch expressions and statements allows you to test expressions against a series of patterns, each with a specified action, enabling you to express complicated data-oriented searches clearly and with confidence. Earlier versions of this feature were released in JDK17 and JDK18.
Record patterns
To break down the record values, a preview of the record pattern was displayed. To enable declarative and highly adjustable data navigation and manipulation, developers can record and type patterns. The proposal aims to extend pattern matching without altering the syntax or semantics of type patterns to describe more complex and flexible data queries.
