In 2020, we observed Java’s 25th birthday by reflecting on its past and showcasing how it remains one of today’s most pervasively used technologies. Through progressive modernization, Java continues to empower developers to create the next generation of rich, scalable, and secure enterprise applications for a variety of targeted deployment environments, including the cloud. In this keynote, learn how Oracle’s ongoing technology and ecosystem stewardship helps create a contemporary language and platform through thoughtful innovation delivered in a predictable and approachable format. With it, developers can thrive in the evolving application development landscape.

With a new, more rapid release cadence, improvements to Java are arriving faster than ever. Experience a whirlwind tour of some of the features planned for the Java programming language in the upcoming months and years.

Helidon and Coherence Community Edition continue to improve support for developing Java microservices with innovations such as MicroProfile API updates, integration with Micronaut and other Java runtimes, GraphQL and GraalVM support, and polyglot client support. This session will introduce you to Helidon and Coherence Community Edition, summarize recent innovations and work in process, and demonstrate how to use these open source frameworks to build scalable microservices.

In this session, you’ll learn how to build Java microservices that have a low memory footprint and start in milliseconds, making them perfect for cloud deployments. These microservices can be built using GraalVM—a high-performance virtual machine that can also compile Java applications into native executables. You’ll receive suggestions for getting started, review various frameworks that work with GraalVM native image, and learn about optimizing performance of native images.

Vector API, incubating in Java 16, enables developers to write platform-agnostic, data-parallel programs where single instructions operate on multiple data (SIMD). Such data-parallel programs, on supporting hardware, are efficiently compiled to vector hardware instructions. They can be more performant that the scalar equivalent: a single instruction operating on a single data element. This talk introduces the Vector API, describes how it was implemented, and presents examples of data-parallel programs with details of how they compile to vector instructions.

Getting up to speed on the new features in Java 16 may seem overwhelming, but your IDE can help. IntelliJ IDEA not only provides support for the latest version of Java, it can also help you discover and use the new language features. Learn how the IDE can help you to migrate to the latest and greatest version—knowing that you won’t need to research the new features until you need them.

Java, its libraries, and the Java virtual machine (JVM) are all built through OpenJDK, an open source project. As many developers with different backgrounds engage in the OpenJDK projects, clear directions are sometimes needed to align developers around terminology and process. The OpenJDK Developers’ Guide aims to provide such directions. While providing a patch may seem like the most obvious way to improve the Java experience, this is not necessarily the case. Learn about the many other ways you can contribute to the OpenJDK project.

Monitoring, troubleshooting, and profiling tools are extremely important for developing reliable, scalable, and performant applications. The Oracle Java Development Kit (JDK) comes bundled with a rich set of tools that help at every phase of the Java application lifecycle. This session will highlight all the monitoring and troubleshooting tools available in the bin folder of the Oracle JDK installation. We’ll examine these tools, their capabilities, and how they can help you extract useful diagnostic information from your Java applications so you can root out and resolve challenging problems.

Got a question about why Java is the way it is, or where it's going? Bring your favorite questions about the Java Platform and the Java Development Kit—past, present, or future—to this open Q&A session with key architects from Oracle's Java team.

Recent features released in Java 15 and Java 16 provide an opportunity to improve application development productivity. In this hands-on workshop, you’ll have a chance to discover and play with some of the most recent Project Amber language features added to the Java platform such as Records, Sealed Classes, Pattern Matching for instanceof, and Text Blocks. You’ll also get to explore Hidden Classes and some of the new Project Panama APIs. Further, you can test-drive a few of the new features of JDK 16 such as Alpine support, new Java Flight Recorder enhancements, and jpackage. There’s no need for you to install anything special as the workshop will use the latest version of Java 16 via an online IDE on Oracle Cloud.

Learn how to deploy Oracle WebLogic Server applications in Kubernetes on Oracle Cloud Infrastructure. You’ll get an overview of WebLogic Kubernetes Toolkit capabilities that enable you to manage the lifecycle of Java EE and Jakarta EE application deployments in Kubernetes clusters. See how to deploy the WebLogic Kubernetes Operator, a load balancer, and create an Oracle WebLogic Server domain in Oracle Container Engine for Kubernetes—the managed Kubernetes environment in Oracle Cloud Infrastructure—and monitor and manage your applications in Kubernetes.

Are you looking to build applications with Micronaut and Oracle Cloud with Autonomous Database? This workshop features several labs that walk you through the steps to get started with Micronaut, Oracle Cloud, and Autonomous Database.

Hear from the two developers who wrote more than 50,000 lines of Java to enable the transition of OpenJDK—relied upon by millions of developers around the world—to Git and GitHub. This session will cover the challenges they faced over the two-year migration as they transitioned an established, open source community using a self-hosted Mercurial server to using Git and GitHub. You’ll hear how they converted more than 65,000 Mercurial commits to Git, created GitHub apps to customize contribution workflow, and scaled pull requests to work for an open source project with more than 250 active contributors.

A preview feature in Java 14 and 15, Records are now final in Java 16. Their close coupling of immutable state and API makes them suitable for several use cases, one of which is serialization. This session will first introduce Records and the concept of serialization. Then, you’ll see a demonstration showing how the properties of Record classes can be leveraged to improve the security, maintainability, and overall performance of serialization.

The introduction of Records has simplified many common use cases in server-side applications. In this session, the co-creator of Micronaut will demonstrate how to get the most out of Micronaut and Records in your applications.

The OpenJFX project defines the JavaFX APIs and implementations that allow developers to create modern, platform-independent user interfaces using Java. At the top-level, JavaFX provides an API that is very similar to the standard Java APIs developers are used to. At the lower level, the JavaFX rendering pipeline integrates with many types of native devices, from desktop systems to mobile and embedded devices. This session explains the structure, components, and roadmap of the OpenJFX project.
