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
