In IntelliJ IDEA
you have to change Project language level
in project settings to 7.0
level:
Underscores in literals are not supported at this language level
문제
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.
