Parameters
long nanosToAdd: The number of nanoseconds to add; this parameter can be positive or negative.
Return value
This method returns a new instance of the Duration class, with the number of nanoseconds added.
Code
In the code below, we add 100000 nanoseconds to the baseDuration object with the help of the plusNanos() method and print the new object to the console.
import java.time.Duration;public class Main{public static void main(String[] args) {Duration baseDuration = Duration.ofSeconds(3);int nanoSecondsToAdd = 100000;Duration newDuration = baseDuration.plusNanos(nanoSecondsToAdd);System.out.printf("%s + %s nanoseconds = %s", baseDuration, nanoSecondsToAdd, newDuration);System.out.println();}}
