How time flies when you’re having fun! Two years ago, we brought you the Annotated Java Monthly, now J.A.M. (homemade at JetBrains) and thanks to tasteful readers like yourself, we now have a number of flavors including the PHP Annotated, C++ Annotated and the Kotlin Digest for you to enjoy. Filled with the freshest ingredients, and following the finest recipes, we preserve all the ripest content, picked from the tallest branches of the most fruitful repositories around the web. Here’s a fresh batch right now, straight from our kitchen to yours. Bon appétit! (more…)

Project Jigsaw. Emerging languages. Android N. Spring 4.3 is in the air and 2016 is already shaping into a productive year for Java developers. Over the last few months, we’ve seen rapid progress on Java 9, and early signs of Java 8 support on Android devices. In this issue of the Java Annotated, we’ll explore future updates to the Java platform, new JVM languages, and open source releases from around the Java community. (more…)

The Java ecosystem is teeming with new technologies. Whether you write mobile apps or middleware, dozens of new libraries and frameworks are released each month. Today’s Java ecosystem is not just growing - but growing up. With the introduction of lambdas and streams, we have seen enormous growth in functional programming and reactive patterns in modern Java. But how on earth is a busy developer to stay ahead of the latest techniques in state-of-the-art Java? As a reader on the Java Annotated, you’re already well on your way. Join us each month, as we explore the latest developments and evolvi

As we turn the calendar on the Java Annotated, we predict the year ahead will bring enormous growth for Java. With lambdas and streams now firmly planted in the Java ecosystem, developers are starting to reap the benefits of functional programming and cultivating new breeds of reactive services and applications. As the largest, healthiest programming language in the world, Java is poised to make real headway in 2016 and already promises exciting innovation in runtimes, frameworks, tools and languages. Stay tuned on the Java Annotated and you’ll stay ahead of the latest developments and emergin

Containers. IoT. Microservices. Reactive programming. These are the trends have driven the evolution of Java over the last twelve months. As web developers are shifting away from monolithic applications toward asynchronous, event-driven services, we have watched these same trends emerge and take hold of the Java community. And these are the topics we’ll be watching closely, in 2016. Until then, happy reading and happy holidays! (more…)

From mobile devices, to middleware, to enterprise applications, Java has played a crucial role in shaping the design of business software for over twenty years. But Java’s audience is both the means of its growth and cause its own captivity. When a programming language is used by nearly half the world’s developers, we seldom stop to ask, “Is there a better way?” There is no question the best years of Java are yet to come, but there is change afoot in the Java ecosystem. Looking toward the next twenty years of Java, we must carefully ask ourselves, where does it lead us? (more…)

Welcome to the Java Annotated Monthly, your source for all the best news and announcements in the Java community! Each month we feature articles from Java developers around the web and hand-pick the most interesting content for your digital consumption. Whether it’s a new library for the JVM or enhancements to your favorite tool, we give equal opportunity to all comers. To submit an article to the Java Annotated, send us a tweet @IntelliJIDEA. It’s Java, Annotated. (more…)

September is off to a busy start for many Java developers, and no busier than right here at JetBrains. Sweeping the chimney and stacking the wood, patching the roofs and packing the goods, we’re making our lists and checking them twice. Each month, we collect the best Java recipes, and each month we find new ingredients to use. Food for thought, from our kitchen to yours - compliments of developers like you. (more…)

At 20 years old, Java remains the world’s most popular programming language this August, with nearly 10 million active developers. If accurate, this figure puts Java slightly ahead of Swedish. While only slightly easier to read, Java has a number of compelling features, including lambdas and streams, intersection types, multiple inheritance, and unrivaled tools and frameworks. If you haven’t seen Java lately, you haven’t seen what Java can do. Join us each month, and stretch your idea of modern Java development. (more…)

At JetBrains we rely on many open source projects, and provide a few of our own as well. Six years ago, we open sourced IntelliJ IDEA and since then, a growing number of developers have chosen the IntelliJ Platform to support their tooling needs, including Android Studio, RoboVM, Cursive Clojure, and hundreds of plugins available on the plugin repository. We are grateful to so many people who trust and contribute to the IntelliJ Platform every day. As part of our commitment to supporting the growing number of developers who depend on these tools at JetBrains and around the world, today we a

Open source is changing the way we build software - as Java developers we see it every day. Millions of applications use open source software to ship Minecraft plugins and spacecraft to Pluto. Open source developers maintain some of the largest engineering projects of our time, with little or no supervision. And open source is secure and reliable. Some of the best software in the world is free and open source, yet we are just beginning to realize the potential of open source collaboration. Join us each month as we explore the latest in open source Java tools and techniques. (more…)

One of the challenges we face with IntelliJ IDEA is showing new users how to quickly become productive. IntelliJ IDEA is a code editor, but it is also a database client, a static analyzer, a version control tool, and for each of these use cases, there are hundreds of individual features. Many of these features are little-known and seldom used, despite being quite useful features. One day, someone may think, “This feature would be nice to have,” and several versions later, there is a new feature. But where is this feature, and how do I use it? (more…)
