Rearmost Features Of Java 16
Rearmost Features Of Java 16
Java is one of the most important programming languages in the software world. Lately, Java 16, the rearmost interpretation of Java, was released on 16th March 2021.
Oracle blazed the vacuum of Java 16 (JDK 16) with 17 new advancements to the platform. This rearmost Java Development Kit release comes with language advancements, new tools, and better memory operation to ameliorate inventor productivity and inflexibility.
According to IDC’s rearmost report “ Java Turns 25”, over nine million mobile app development companies representing 69% of full- time developers worldwide use Java — this is further than any other language.
Java 16 What’s New?
JDK 16 offers performance, security, and stability updates along with 17 main changes that are known as JDK Improvement Proffers — JEPs.
- Crucial Highlights Of Java 16
- Language advancements that were introduced in JDK 14 and perfected in JDK 16
- Advanced memory operation
- New Packaging Tool
- UNIX-Domain Socket Channels
- Warning for Value- grounded Classes
- Recapitulating JDK Internals by dereliction
- Enable C 14 Language Features
- Incubating and Preview Features
- Language Enhancement
Pattern matching and records were introduced in Java 14 as exercise features and are now enforced in Java 16.

Pattern Matching For Instanceof
The instanceof driver in Java is used to check object reference. It returns either true or false values and checks whether an object belongs to a parent class, child class, or an interface. It’s also used to check the type of object.
Still, the coming step is to explicitly cast it to the specific type that’s being compared, If this result returns true. Pattern Matching for cases in Java helps remove the spare law of casting by introducing the Pattern Matching variable.
With this JEP, the instanceof driver comes with a pattern variable.However, the pattern variable binds to the variable being compared, If the instanceof condition is true. This removes the need for unequivocal casting and allows tentative birth of factors from objects more safely and easily.
Another point that was introduced in Java 14 and Java 15 is Records. Record is a special Java class that offers a compact syntax for defining inflexible data classes.
This will simplify passing inflexible data between objects. Before this, it was a mundane task to pass inflexible data as it needed boilerplate styles and classes. Record simply designed to hold data in it.

Improved Memory Management
These two new features are introduced in Java 16 — Elastic Metaspace and ZGC Concurrent Thread-Stack Processing.
We’ll see these two features in detail.
The primary function of Metaspace is to manage memory for class metadata. Elastic Metaspace is introduced to ameliorate the allocation and deallocation of metaspace memory in the HotSpot JVM. This is used to return unwanted memory to the OS more snappily, thereby reducing above and memory fragmentation.
It allocates memory in lower gobbets and improves pliantness by returning unused metaspace memory to the Zilches. It leads to lesser performance and reduced conservation costs.
ZGC Concurrent Thread-Stack Processing
Oracle’s Z Garbage Collector is one of the low- quiescence collectors in the HotSpot JVM. This JEP moves ZGC thread- mound processing from safepoints to a concurrent phase.
New Packaging Tool
This was also introduced in Java 14 as an incubator module. This new Packaging tool can be used for packaging tone- contained Java operations. To give druggies a natural installation experience, it supports native packaging formats.
Unix-Domain Socket Channel
Unix-Domain sockets are analogous to TCP/ IP sockets and are used forinter-process communication (IPC) on the same host Zilches. Unlike TCP/ IP sockets, these sockets are addressed by train system path names rather than IP addresses and harborage figures.
They’re more secure and effective than TCP/ IP loopback connections. Java 16 adds support for all of the features of UNIX- sphere sockets. Now, Java’s socket channel/ garçon-socket channel API can use Unix sphere sockets for briskly and effective IPC on the same host. Before Java 16, this was limited to TCP/ IP sockets.
Warning For Value- grounded Classes
This JEP designates the primitive wrapper classes as value- grounded and deprecates their constructors for junking, causing new deprecation warnings.
It provides warnings on indecorous attempts to attend on cases of any value- grounded classes.
Recapitulating JDK Internals By Dereliction
This is enforced with a goal to continuously ameliorate the security and maintainability of the JDK. This JEP denotes the strong encapsulation of all internal rudiments of the JDK — except for some critical internal APIs.
This further encourages inventors to resettle from using internal rudiments to using standard APIs, so inventors can fluently upgrade to unborn Java releases.
Enable C 14 Language Features
This JEP enables the use of C 14 language features in JDK C source law. It also offers guidance on which of these features may be used in HotSpot law.
This JEP, along with JEP 357 and JEP 369 is concentrated to ameliorate productivity for OpenJDK inventors.
The abovementioned JEPs resettle the source law depositories of the OpenJDK community from Unpredictable to Git and host OpenJDK’s Git repositories on GitHub.

Incubating And Preview Features
This Incubator Vector API is an original replication of an incubator vector module. It expresses vector calculations that collect at runtime to optimal vector tackle instructions. This vector API is grounded on the principle that Java inventors should be suitable to use any native library that’s needed for a particular task.
Foreign Linker API
This API offers statically compartmented, pure Java access to native law.
Foreign-Memory Access API
It allows Java programs to safely and efficiently access foreign memory outside of the Java mound. It also provides the foundation for the Foreign Linker API.
This alternate exercise of sealed classes restricts which other classes or interfaces may extend or apply them. It allows the author to control which law is responsible for enforcing it.
