Java 8 and Method References in IntelliJ IDEA 12
October 22nd, 2012 by Anna KozlovaAs 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 highlights anonymous types which can be replaced with a method reference.
After you apply provided quick-fix, it gets just a line of code.
There is also another inspection that checks if a lambda expression in your code can be replaced with a method reference.
You can also use an intention to replace a method reference with a lambda expression, in the case when you need additional logic.
All the common features such as completion, refactorings, formatting and many other were updated to support method and constructor references.
As always you are very welcome with suggestions and feedback in our issue tracker.
Develop with Pleasure!

No way to use this version. Every time I got “window blue screen of the death”. I’m using Windows 7 64 bits, JVM 1.7.0_09 64 bits.

Do we have to launch the IDE from one of the Lambda builds to experiment with this?
Available at http://jdk8.java.net/lambda/

Aaron, you don’t need to start IDEA on jdk 8, but you need to configure JDK for your project to use JDK 8 with lambda support.
Thanks
