A look at Java 17 and Beyond

Java is one of the most popular and enduring programming languages. Every new Java release brings new features, improvements, and performance improvements. The purpose of this article is to explore the latest developments in the Java world, including Java 17 and why it’s important to keep your Java version up-to-date.

The Evolution of Java Releases

Here’s an overview of how Java’s release cycle has evolved over the years. Java used to release major versions every few years, following a traditional release cycle. A backlog of features often resulted from this approach, making it challenging for developers.

Java was introduced with a new cadence in 2017, adopting a time-driven model. A six-month release schedule provides a predictable and more frequent Java release schedule. Feature releases and Long-Term Support versions are included in these regular releases.

  • LTS Versions: LTS versions, such as Java 11 and Java 17, are supported for a longer duration, typically for eight years. They are well-suited for enterprise applications and production environments.

  • Feature Releases: These non-LTS releases, like Java 16 and Java 18, introduce cutting-edge features, improvements, and experimental features. They are perfect for developers who want to stay at the forefront of Java development.

Java 17: The Latest LTS Release

The latest LTS version of Java was released in September 2021. A compelling choice for developers and organizations, it comes packed with several notable features. Java 17 features:

1. Sealed Classes

Sealed classes and interfaces bring a new level of control over class hierarchies. With the sealed modifier, you can explicitly define which classes can extend or implement a sealed class, making your codebase more maintainable and secure.

2. Pattern Matching

Pattern matching simplifies the code by introducing a more concise and expressive syntax for conditional operations. The introduction of instanceof patterns and the switch expression greatly enhances code readability.

3. Foreign Function and Memory API (Incubator)

Java 17 introduces the Foreign Function and Memory API as an incubator feature. This allows for seamless interaction with native code and memory management, making it easier for Java to interface with libraries written in other languages like C and C++.

4. Strong encapsulation of JDK internals

Java 17 enhances security by strengthening the encapsulation of JDK internals. This makes it harder for developers to accidentally access internal APIs that could lead to compatibility issues and security vulnerabilities.

5. macOS Rendering Pipeline

For macOS users, Java 17 comes with a new rendering pipeline that enhances performance and provides a more native look and feel for graphical applications.

Benefits of Keeping Java Up to Date

Now that we’ve explored some of the key features of Java 17, it’s essential to understand why keeping your Java version up to date is crucial:


Regular updates often include security patches that protect your applications from vulnerabilities and cyber threats. Staying on an LTS release ensures that you receive security updates for an extended period.


Newer versions of Java often bring performance improvements, which can lead to faster and more efficient applications. Taking advantage of these improvements can give your applications a competitive edge.

Language Features

Each release introduces new language features and APIs that can help you write cleaner, more concise, and more maintainable code. Staying up to date ensures you can leverage these features to their fullest.

Community and Ecosystem

The Java community is vibrant and active if you stay current with Java versions. The latest Java releases will provide you with more resources, libraries, and tools.

The Java platform has entered an era of rapid innovation with Java 17 and the new release cadence. With a predictable release schedule and a wealth of new features, it’s in your best interest as a developer or organization to embrace the latest Java versions. Whether you opt for an LTS release or experiment with feature releases, staying up to date with Java will ensure that your applications remain secure, performant, and ready for the future.

So, don’t wait – upgrade your Java version today and start benefiting from the latest and greatest features that the Java ecosystem has to offer.

By keeping up with the latest Java releases, developers can ensure that they remain competitive, efficient, and secure in the ever-evolving world of software development. This article provides an overview of Java 17 and the benefits of staying current, but it’s essential to stay tuned for further developments in the Java ecosystem as new versions and features continue to emerge.
