What is Java version 18?

Introduction

Java 18, also known as OpenJDK 18 or Oracle JDK 18, is the latest release of the Java programming language platform. It was officially announced on March 22, 2022, as a feature release, rather than a Long Term Support (LTS) release. In this article, we will delve into what Java 18 is all about, its key features, and why it matters.

What is the Java Platform?

Before we dive into Java 18, it’s essential to understand what the Java platform is. The Java Platform, Standard Edition (SE) is a widely-used programming platform that provides the necessary tools and libraries to develop and run Java-based applications. The Java Platform is designed to provide a robust, scalable, and secure environment for building cross-platform applications.

Overview of Java 18

Java 18 is built on top of the JDK 18, which introduces several new features, including virtual threads, structured concurrency, and improved performance. The JDK 18 provides a set of enhancements aimed at improving the performance and reliability of Java applications. Some of the key highlights of Java 18 include:

• Virtual threads: Java 18 introduces virtual threads, which replace traditional threads. Virtual threads provide a more efficient way of handling concurrency, resulting in improved performance and reliability.
• Structured concurrency: Java 18 also introduces structured concurrency, which provides a way to compose and manage concurrent code using structured APIs.
• Improved performance: Java 18 includes several performance-enhancing features, including incremental garbage collection and improved multithreading.

Comparison with Previous Releases

Before we explore the new features of Java 18, let’s take a quick look at how it compares to previous releases. In the table below, you can see the major improvements and changes between Java 17 and Java 18:

Key Features

Now that we’ve reviewed the comparison, let’s dive into the key features of Java 18 in more detail:

• Virtual threads: Virtual threads are a significant improvement in Java 18, offering a more efficient way to handle concurrency. They enable developers to write more predictable and scalable code, improving the overall performance of the application.
• Structured concurrency: Structured concurrency provides a way to manage and compose concurrent code in a more structured and modular way. This makes it easier to write and maintain concurrent code.
• Improved performance: Java 18 includes various performance-enhancing features, such as incremental garbage collection and improved multithreading. These improvements result in faster and more efficient Java applications.

Conclusion

In conclusion, Java 18 is the latest release of the Java programming language platform, offering significant improvements in performance, concurrency, and reliability. The virtual threads and structured concurrency features provide a more efficient and scalable way of handling concurrent code, while the incremental garbage collection and improved multithreading enhance the performance of Java applications.

With Java 18, developers can build more robust and scalable applications, leveraging the latest advancements in Java development. Whether you’re looking to improve performance, develop concurrent applications, or expand your Java skills, Java 18 is an essential release to explore.
