Duration toNanos() method in Java with Examples Last Updated : 26 Nov, 2018 Comments Improve Suggest changes Like Article Like Report The toNanos() method of Duration Class in java.time package is used get the value of this duration in number of nano-seconds. Syntax: public long toNanos() Parameters: This method do not accepts any parameter. Return Value: This method returns a long value which is the number of nano-seconds in this duration. Below examples illustrate the Duration.toNanos() method: Example 1: Java // Java code to illustrate toNanos() method import java.time.Duration; public class GFG { public static void main(String[] args) { // Duration using parse() method Duration duration = Duration.parse("P2DT3H4M"); System.out.println("Duration: " + duration); // Get the number of nano-seconds // using toNanos() method System.out.println(duration.toNanos()); } } Output: Duration: PT51H4M 183840000000000 Example 2: Java // Java code to illustrate toNanos() method import java.time.Duration; public class GFG { public static void main(String[] args) { // Duration using ofNanos() method Duration duration = Duration.ofNanos(10); System.out.println("Duration: " + duration); // Get the number of nano-seconds // using toNanos() method System.out.println(duration.toNanos()); } } Output: Duration: PT0.00000001S 10 Reference: https://docs.oracle.com/javase/9/docs/api/java/time/Duration.html#toNanos-- Comment More infoAdvertise with us Next Article Duration ofNanos(long) method in Java with Examples C code_r Follow Improve Article Tags : Java Java-Functions Java-time package Java-Duration Practice Tags : Java Similar Reads Duration toNanosPart() method in Java with Examples The toNanosPart() method of Duration Class in java.time package is used get the nanoseconds part within seconds of the duration.
