IntelliJ IDEA 13.1 RC2 Ships Nearly Final Java 8 Support

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 blogged about the coding assistance for Java 8 (in v12 and v13).  Now let’s see what new exciting features v13.1 can offer.

In addition to overall enhancements in support, IntelliJ IDEA 13.1 comes with a new inspection helping you migrate your code to the new Stream APIs. Here’s a short demo:

 

As you can see from this demo, the IDE also helps you understand which method is used for your lambda expressions by showing a clickable icon on the gutter.

In case you’d like to apply the corresponding quick-fix to more than one place in your code, you can run this inspection (“foreach loop can be collapsed with stream api”) on the entire project (or another scope) via AnalyzeRun inspection by Name.

We hope this coding assistance will help you improve your code and make migration to the new JDK easier.

We’d like also to remind you about an upcoming webinar with Dr. Venkat Subramaniam on functional programming with Java 8, taking place Wednesday, March 26th, at 11:00 AM – 12:00 PM GMT. In this presentation, we will discuss how Java 8 now facilitates a functional style of programming and why we should care about it. Space is limited, so please register now.

Meanwhile, please share your thoughts in our discussion forum and submit your bug reports to the issue tracker.

Develop with Pleasure!

  1. Hello,

    Will you ship IntelliJ 13.1 with JDK 8 bundled on OS X and Windows? I think, it’ll be cool to do it and it can be help the migration to JDK 8. I hope that JDK 8 will be rapidly adopted.

    • Sergey says:

      I do not think that inclusion of jdk8 will repid the adoption of it. I think that developers will wait for 5-10 minor jdk8 updates before installing it on production server.

    I installed. I click about. It’s still using 1.6 JRE on OSX. Slow.

    Also some webstorm features still don’t work. For example file watcher.

  3. Eugene says:

    Does it work correctly under JDK 8 only?

  4. puli says:

    Hi.. I would like to know how to configure IntellilJ IDEA compiler version to use java 8 instead java 6. I have jdk 8 installed properly on Linux. I am new to IntellilJ IDEA.
    Thanks in advance.
