operator is not allowed for source level below 1.7

Question

I am getting below error while compling code in Eclipse.

'<>' operator is not allowed for source level below 1.7

I have even changed my reference library to point to JDK 1.7.

Answer 1

In Eclipse,

go to Project > Properties

From left hand side, click Java Compiler.

Make sure that "Enable project specific settings" is checked.

Select "Compiler compliance level" equilent to JDK library you have included in your build path.

In your case it should be 1.7.
