Top JDK 20 New Features: Every Java Developer Must Know In 2023

Java has a significant global presence. And Java tools are a boon to developers because of their ease of use and comprehensive features. The JDK 20 New Features are yet to release in the new year. And these features include scoped values, pattern matching, a foreign function, memory API, virtual threads, etc. Furthermore, we noticed some minor changes from JDK 19. Let’s take a closer look at the features.

An overview of JDK 20 new features

Java 20 will be available in a few months. As of JDK 20 new features are available to developers. We will provide you with an overview of these features. However, we can predict which JEPs will be in Java 20 based on JEP draughts and JEP candidates. JDK Source Structure is a JEP that describes the JDK source code and repository. It assists developers in adapting to the source code structure described in JEP 201, Modular Source Code, which is in JDK 9.

Extensive JDK 20 new features

Here are some features of Java 20 you would notice in the coming months.

Scoped values

When talking about JDK 20 new features, we jump to scoped values. It is a beta API for developing and sharing immutable data across threads. These are thread-specific variables. Especially when using multiple virtual threads. A scoped value enables data to share between components securely and efficiently. And without resorting to method arguments in a large program. It improves usability, comprehension, and performance.

Record patterns

In the second set of JDK 20 New Features focuses on improving Java programming patterns. For deconstructing record values. Record and type patterns can also be nested to enable declarative and powerful data navigation and processing. Extending pattern matching for more refined, composable data queries is their goal.

Not to mention not changing the syntax of type patterns. The main changes since the first preview in JDK 19 include the addition of type inference support. And the generic record pattern arguments allow record patterns to appear in the header. In addition, named record patterns are no longer supported.

Foreign functions

It adds an API to help Java programs interact with code and data outside of the Java runtime. This API allows Java programs to interact with native libraries and native data. And all without the fragility and danger of the Java Native Interface. As a result, this API was incubated in JDK versions 17 and 18 and previewed in JDK 19. You can hire Java developers for more technical guidance. Furthermore, these classes added since JDK 19. Moreover, it includes the unification of the MemorySegment and MemoryAddress abstractions. It is an improved MemoryLayout hierarchy, as well as the division of MemorySession into Arena and SegmentScope. Furthermore, it is to encourage segment sharing across maintenance boundaries.

Virtual threads

These are lightweight threads designed to reduce the time spent writing, maintaining, and running high-throughput concurrent applications. Several API changes have been made since the first preview of JDK 19. And ThreadGroup degradations, as in JDK 19. A traditional Java thread corresponds to a single OS thread. Whereas, virtual threads are not bound to a specific OS thread. As a result, they are inexpensive to produce and can be created in large quantities.

Structured concurrency

So it’s yet another feature that can help an API simplify multithreaded programming. And it treats multiple tasks from different threads as a single unit of work. Error handling and cancellation are streamlined, increasing reliability and observability. The only difference since it was incubated in JDK 19 is StructuredTaskScope. Furthermore, it is updated to support the inheritance of scoped values by threads created in a task scope. You can hire Java developers for more technical guidance.

Pattern matching

As a result, it’s yet another feature that can help an API simplify multithreaded programming. Also, multiple tasks from different threads are treated as a single unit of work. Error handling and cancellation are simplified, increasing reliability and observability. StructuredTaskScope is the only thing that has changed since it incubates in JDK 19. Furthermore, it has updates to allow threads created in a task scope to inherit scoped values.

Primitive classes

JEP 401 adds support for a new special value class that can be used to define primitive types. These primitives improve performance by allowing for faster memory access. This JDK 20 new feature involves primitive operations performed more efficiently within the CPU. Developers can now reap the performance benefits of primitives thanks to this update. Also, keep the abstractions and other advantages of class declarations. Primitive classes must follow two rules to reap the benefits of traditional object orientation:

• All fields in a primitive class are implicitly defined as final, which means they can only be set within a function.
• Furthermore, primitive classes cannot have fields that rely on the declaring class implicitly.

Value objects

Traditional Java objects provide identity, which means their memory location is used to differentiate one object from another. Offering identity is expensive at runtime and is frequently against in implementations. This submission adds value classes and value objects to Java’s object model. Value classes are identity-free.

And it means they can provide the performance advantages of primitive types while utilizing object-oriented concepts. When using the == operator on value objects, the values of their fields determine equality. Rather than their memory location. Remember that all value class fields are implicitly final and must be set in an initializer or function Object()!
