lambda expressions not working in netbeans jdk 1.8 project

Question

Even though I changed my netbeans project's jdk to 1.8, it still gives the following error

lambda expressions not expected here

lambda expressions are not supported in-source 1.7
(use source 8 or higher to enable lambda expressions)

Any help is so much appreciated

Is this a Maven project? It must be specified in your project's pom.xml. — starf, Mar 07 '16 at 19:52
In the project properties, did you only set Libraries->Java Platform or did you also set Source->Source/Binary Format? — Thomas Kläger, Mar 07 '16 at 19:53
thanks a lot @Thomas, I didn't set the later one. Now It work's perfect. — andy, Mar 07 '16 at 19:55

You have to set the project properties for the target version. Java 8 allows you to build for Java 7 execution, and that setting is still there from when you used Java 7. Right-click on the Project in the "Projects" window and select "Properties", then "Sources" in that dialog. On the right you will see "Source/Binary Format". Change that to "1.8", then click "OK".
