Duration withNanos() method in Java
The immutable copy of a duration with the required nanoseconds is obtained using the method withNanos() in the Duration class in Java. This method requires a single parameter i.e. the number of nanoseconds and it returns the duration with the required nanoseconds that were passed as a parameter.
A program that demonstrates this is given as follows −
Example
import java.time.Duration;
public class Demo {
public static void main(String[] args) {
int nanoseconds = 1000000;
Duration duration = Duration.ofHours(10);
System.out.println("The duration is: " + duration.withNanos(nanoseconds));
}
}Output
The duration is: PT10H0.001S
Now let us understand the above program.
The immutable copy of the duration with the required nanoseconds is obtained using the method withNanos() and then it is printed. A code snippet that demonstrates this is as follows −
int nanoseconds = 1000000;
Duration duration = Duration.ofHours(10);
System.out.println("The duration is: " + duration.withNanos(nanoseconds));
