We've taken on board suggestions from last month's experiment and this month we're trying to please everyone - what could possibly go wrong? February is a short month so you might expect a shortage of news, but far from it!  It's a big year for releases, with Java 9 and Java EE 8 on their way, and it's never too early to get up to speed on what's coming.

I've been giving a talk this year showcasing how to use IntelliJ IDEA inspections to help you refactor existing code to Java 8. The initial version of this, the one I gave at DevoxxUK (video), is based on my Migrating to Java 8 Tutorial. I've also written before about how IntelliJ IDEA can help you write more idiomatic Java 8 code. I'm revisiting the topic now that IntelliJ IDEA 2016.3 has adde

The froth of JavaOne has died down (already!) and it's almost back to business as usual. Although here at JetBrains we're working hard on our latest product releases, and gearing up to see some of you at Devoxx this week. This month's annotated monthly looks outward to more than just things that impact Java and the JVM, and pulls together content that affects all developers, like design, architect

September is a busy conference month, in particular a number of the Java-related JetBrains team were at JavaZone and JavaOne.  To save you some time, cash, and pain, October's annotated monthly is going to be a little heavy on links to videos and slides - we go to conferences so that you don't have to.

A new IntellIJ IDEA 2016.3 EAP build is out and ready to try. Other than the usual amount of bugfixes, it brings a couple of noticeable improvements. More Refactorings to Java 8 First of all, we continue with tuning the inspections that help refactor regular code into idiomatic Java 8. (more…)

Hooray! Fresh IntelliJ IDEA 2016.3 EAP build is out! Among the numerous bugfixes, this build addresses one of the issues that prevented it from being used on macOS Sierra. Users of macOS Sierra, we're kindly asking you to thoroughly test this build and let us know if the problem is gone. Faster Search in Git Log The new build brings a dramatic speed improvement to searching thru Git Logs, pa

In one of her recent articles, Trisha Gee wrote about refactoring to Java 8. Among many great tips about Java 8, the article also showed how IntelliJ IDEA helps write correct and idiomatic Java 8. With IntelliJ IDEA 2016.3, we've gone further and extended our existing inspections to support non-trivial cases. (more…)

I’ve been working a lot with Java 8 code over the last couple of years, for both new applications and migrating existing ones, and it feels like the right time to write down some of the “best practices” I’ve found useful. I personally dislike the term “best practices” as it implies a “one size fits all” solution, and of course coding doesn’t work that way - it’s down to us as developers to figure

Since Java 8 has been launched almost two years ago, it has been gaining more and more traction around the community. Most Java frameworks and platforms have either already migrated their APIs to Java 8, or are planning to do so. With our latest update, the whole IntelliJ Platform has migrated to Java 8, which has allowed both ourselves and plugin developers to use the new language features. Am

The release of JDK 8 has introduced a number of new language features into Java vernacular. In this issue of The Inspection Connection, we will examine eight useful inspections that IntelliJ IDEA provides to help you become more fluent in functional programming on Java 8, migrate your legacy code, detect bugs sooner, and develop with pleasure. 1. Anonymous type can be replaced with lambda As a

Today’s Java landscape is growing larger and faster than ever, with over 30,000 new Java projects created on GitHub each month. Here on the Java Annotated Monthly we leave no stone unturned to bring you the most important news and developments around the world. All the news, fit to println(“Develop with pleasure!”); Java Project Valhalla - Project Valhalla is an exp

Here’s a few stories we’ve been reading on the Java beat this month, straight from the source. If you have any news or articles you would like to see here on the Java Annotated Monthly, you can reach me, Breandan dot Considine at JetBrains or @breandan.

Last Friday we announced the availability of IntellIJ IDEA 13.1 RC2, a new release candidate for IntelliJ IDEA 13.1 bringing final support for Java 8. In other awesome news, besides coding assistance for Java 8 the new build also provides a built-in debugger for JDK8’s Nashorn. Nashorn is the new lightweight high-performance JavaScript runtime built on top of JVM. With IntelliJ IDEA 13.1 RC2, now

It’s always nice to start the day with a fresh build of IntelliJ IDEA and its fresh-out-of-the-oven features. But that pales in comparison with being the first explorer of final Java 8 support in your favorite IDE! IntelliJ IDEA 13.1 RC2 is available for download, shipping final improvements for Java 8 support just a few days ahead of its official release. As you may remember, we’ve already blog

As you might know IntelliJ IDEA 12 will bring support for new features of Java 8 language. Though this is still in progress, you can try some of these features now in IntelliJ IDEA 12 EAP. Here we would like to provide some details on method and constructor refereces support. IntelliJ IDEA as always provides a way to transform existing code to use new features. Dedicated inspection finds and hig

A new EAP build 122.202 of IntelliJ IDEA 12 has been released. The build contains improved JDK8 lambda inference and initial code insight features: Anonymous class can be replaced with lambda inspection with a quick fix Intention to replace lambda with anonymous class Intention to insert inferred lambda parameter types You can find the complete list of changes in the build.
