Underscores in literals are not supported at this language level

I got this error when creating a final double using underscores to make the double more readable. It was declared in a run() method.

public void run() {        
    final double nanoSeconds = 1_000_000_000.0 / 60.0;    
}

I'm using IntelliJ IDEA 12.

Yes..you need to change the default language level settings if you are using and IDE. For IntelliJ users it is under File --> Project Structure --> Projects.
