        Duration duration = Duration.ofSeconds(5, 100);
        System.out.printf("Seconds in %s - %s", duration, duration.get(ChronoUnit.SECONDS));

Explanation

  • In lines 1 and 2, we import the relevant packages.
  • In line 7, we define a Duration object having 5 seconds and 100 nanoseconds.
  • In line 8, we print the seconds part of the Duration object created in line 7 with the help of get() method with ChronoUnit.SECONDS as the unit of time.
  • In line 9, we print the nanoseconds part of the Duration object created in line 7 with the help of get() method with ChronoUnit.NANOS as the unit of time.
