Java 16 Features

JDK 16 is the open-source reference implementation of version 16 of the Java SE Platform as specified by JSR in the Java Community Process. 

After jdk 15 released oracle is working on JDK16 and JDK17. 

Some of the important Java 16 features are:

Java 16 Features:
JEPs targeted to JDK 16, so far

357: Migrate from Mercurial to Git
369: Migrate to GitHub
347: Enable C++14 Language Features

338: Vector API (Incubator)

387: Elastic Metaspace

386: Alpine Linux Port

376: ZGC: Concurrent Thread-Stack Processing

386: Alpine Linux Port

388: Windows/AArch64 Port

Some More java 16 features are coming up. We will discuss once openjdk Java Community Process released some information.

This release will be the Reference Implementation of version 16 of the Java SE Platform, as specified by JSR 391 in the Java Community Process.

What's new in Java 16?

357: Migrate from Mercurial to Git

Migrate all single-repository OpenJDK Projects from Mercurial to Git

369: Migrate to GitHub

Host all OpenJDK Git repositories at https://github.com/openjdk/.

Features:

Enable C++14 Language Features:

Allow the use of C++14 language features in JDK C++ source code, and give specific guidance about which of those features may be used in HotSpot code.

338: Vector API (Incubator):

jdk.incubator.vector, express vector computations that reliably compile at runtime to optimal vector hardware instructions on supported CPU architectures and thus achieve superior performance to equivalent scalar computations.

JEP 387: Elastic Metaspace:

Return unused HotSpot class-metadata (i.e., metaspace) memory to the operating system more promptly, reduce metaspace footprint, and simplify the metaspace code in order to reduce maintenance costs.

JEP 386: Alpine Linux Port

This JEP intends to integrate the Portola Project upstream.

JEP 388: Windows/AArch64 Port

This port includes the template interpreter, the C1 and C2 JIT compilers, and a limited set of garbage collectors (serial, parallel, and G1). 

It supports both the Windows 10 and Windows Server 2016 operating systems.
