The release possibly could include brand-new functionality for universal generics, immutable data, and string templates and finalize abilities such as record patterns.The current OpenJDK web page for JDK 20 lists no officially proposed functions as of September 23, however that will alter quickly enough.
Capabilities that might make it into Java 20 consist of: Universal generics, to unify the treatment of referral and primitive enters generic code. This proposal has been drifting for a while and did not make it into JDK 19. Extent-local variables, to make it possible for sharing of immutable information within and across threads. String templates, to simplify Java programming by making it simple to express strings that consist of worths computed at run time. Value items, to enhance the Java things model with class circumstances that have just last circumstances and do not have things identity. Primitive classes, which are special sort of value classes that define brand-new primitive types. Sequenced collections, supplying a Collection interface to representa collection with a specified encounter order.
An API for asynchronous stack traces, which would supply information on Java and native frames. A classfile API, to parse, generate, and transform Java
class files. Tape-record patterns, previewed in JDK 19, for deconstructing record worths. Foreign function and memory API, previewed in
JDK 19 as a system for Java programs to interoperate with code and information outside the Java runtime. Another JDK 19 preview function, virtual threads, functions as light-weight threads to make it much easier to write and maintain high-throughput concurrent applications. A vector API, nurtured for a 4th time in JDK 19, expresses vector computations that dependably compile at runtime to ideal directions on supported CPU architectures, achieving much better performance than scalar computations. Structured concurrency, in an incubator phase in JDK 19, would simplify multithreaded programs via an API.
Pattern matchingfor switch expressions and declarations, previewed for a third
time in JDK 19, to improve Java programs. Based upon standard Java’s six-month release cadence, Java 20, or Java Development Kit 20, would show up as a production release
in March 2023. Like JDK 19, JDK 20 would be a short-term release with only 6 months of premium assistance from Oracle. The following JDK 21 is due in a year and would
be an LTS( Long Term Support)release with numerous years of support by Oracle. Copyright © 2022 IDG Communications, Inc. Source
