Parameters
The method doesn’t take any parameters.
Return value
The method returns the converted equivalent of the ChronoUnit date period unit.
Code
-
In the code below, we create a
TimeUnitobject. -
Then we check whether the method
toChronoUnit()returns an object that is not null as is the instance of theChronoUnitclass.
Then we print the value returned by the method to the console.
import java.time.temporal.ChronoUnit;import java.time.LocalDateTime;import java.util.concurrent.TimeUnit;class Main {public static void main(String[] args){TimeUnit time = TimeUnit.MINUTES;assert time.toChronoUnit() != null && time.toChronoUnit() instanceof ChronoUnit;System.out.println("Convert from TimeUnit to ChronoUnit - " + time.toChronoUnit());}}
Output
Convert from TimeUnit to ChronoUnit - Minutes
