Error: "binary literals are not supported at this language level "

Question

I am using JDK 1.7 and getting the error "binary literals are not supported at this language level" when I attempt to use expressions such as:

 int x = 0b000001;

I thought binary literals were supported by 1.7?

Answer 1

Solution in Intellij 13.2 and similar: Select menu choice File/Project Structure. The following dialog appears:

Set Project language level to be what is needed (7.0 for binary literals).
