I am using NetBeans 8. When my code contains a Lambda expression and I try to compile, I get the following error message:
lambda expression not expected here lambda expressions are not supported in -source 1.5 (use -source 8 or higher to enable lambda expressions) ---- (Alt-Enter shows hints)
Please click right from you project -> Properties -> Choose Sources -> (you will see Source/Binary Format) change it to 1.8 -> Click OK.
Or you can see in this link http://tinadev.blogspot.com/2015/08/lambda-expression-not-expected-here.html
Thanks
将源代码的编译器版本更改为项目属性为jdk 8,并首先检查是否已安装。
在项目属性对话框中,在左侧面板中选择“源”,然后在右下角查找“源/二进制格式”,将其更改为JDK 8。
Download JDK 1.8 to resolve this issue. change the JAVA_HOME environment variables path to jdk_1.8. Right Click on the project folder which has the above mentioned compilation error and select properties. In Sources tab change the source/binary format to JDK 8. In libraries change Java Platform to JDK 1.8.
