android detect if night

Question

Is there a better way than this?

Boolean isNight;
Calendar cal = Calendar.getInstance();
int hour = cal.get(Calendar.HOUR_OF_DAY);
if(hour < 6 || hour > 18){
    isNight = true;
} else {
    isNight = false;
}

It just checks if hour is between 7pm and 5am. Is there any other way to do this?

Answer 1

Not a big difference, but you can make an assignment:

isNight = hour < 6 || hour > 18;
