  • Java InfoQ Trends Report—September 2020

    This article provides a summary of how the InfoQ editorial team currently sees the adoption of technology and emerging trends within the Java space in 2020. We focus on Java the language, as well as related languages like Kotlin and Scala, the Java Virtual Machine (JVM), and Java-based frameworks and utilities.

  • TornadoVM: Accelerating Java with GPUs and FPGAs

    The proliferation of heterogeneous hardware represents a problem for programming languages such as Java that target CPUs. TornadoVM extends the Graal JIT compiler to take advantage of GPUs & FPGAs and provides a flexible, high-level model whilst still enabling high performance and features such as live task migration.

  • Understanding Classic Java Garbage Collection

    Java Garbage Collection remains a topic of major interest even after 25 years. Many developers are still confused about the fundamentals of the topic, even of the most widely-used implementation (Parallel on Java 8).

  • Java Feature Spotlight: Local Variable Type Inference

    In Java Futures at QCon New York, Java Language Architect Brian Goetz took us on a whirlwind tour of some recent and future features in the Java Language. In this article, he dives into Local Variable Type Inference.

  • A First Look at Java Inline Classes

    Java currently supports only two types of value: primitives and object references. Project Valhalla extends this by introducing inline classes which are a new form of type that exhibit some behaviors of both. These new types open the door to better alignment with modern CPUs and considerable potential performance improvements for Java applications.

  • Upgrading from Java 8 to Java 12

    Why upgrade to Java 12? Lots of things have changed since Java 8: licensing, updates and support. On top of that, there are new language features. Now that major libraries, frameworks and build tools have adopted the latest versions of Java, it is a good time to migrate your application to Java 12.

  • Interview: Today's Java with Cay Horstmann

    Cay S. Horstmann, author of Core Java Volumes 1 & 2, has written about Java since the beginning. Topics include the forthcoming Java 8, Java's vendor support, and the language's role in modern software development.

  • Oracle and the Java Ecosystem

    Oracle is making huge efforts to engage with the wider Java ecosystem, but challenges still remain.

  • A Brief Introduction to the Java and .NET Patent Issues

    With the recent legal battle between Google and Oracle there is a renewed focus on the patent issues for Java and .NET. Tim Smith introduces the licenses offered by Oracle/Sun and Microsoft, with a focus on how they may affect third party implementation. Possible motivations for Google Android’s unique implementation are also covered.

  • JSR 292 and the Multi-lingual JVM

    Java 7 is looking to improve support for dynamic languages using the Java Virtual Machine for their runtime environment. John Rose has been leading a project to explore some options, and JSR 292 will standardise some of this work for Java 7. InfoQ takes a look at the problems JSR 292 solves, and talks to JRuby lead Charles Nutter to find out more about InvokeDynamic in practice.

  • Evolving Java Without Changing the Language

    InfoQ examines three techniques for encouraging experimentation with potential new Java language features - DSLs, the annotation processor, and moving the syntactic sugar from the language to the IDE.

  • Modular Java: What Is It?

    Over the last few years, modularity for Java has been an active discussion topic. From the (now defunct) JSR 277 to the recognition of JSR 291 and the ongoing JSR 294, modularity is seen as a necessary step in Java's evolution. Even future JVM-based languages like Scala are considering modularity. So, what does modularity mean, and why should you care?
