OffsetDateTime plusNanos() method in Java with examples Last Updated : 17 Dec, 2018 Comments Improve Suggest changes Like Article Like Report The plusNanos() method of OffsetDateTime class in Java returns a copy of this OffsetDateTime with the specified number of nanoseconds added to the parsed date and time. Syntax: public OffsetDateTime plusNanos(long nanoseconds) Parameter: This method accepts a single parameter nanoseconds which specifies the nanoseconds to be added to the parsed date. It can be negative also, in that case, it subtracts the number of nanoseconds to it. Return Value: It returns an OffsetDateTime based on this date-time with the nanoseconds added and not null. Exceptions: The program throws a DateTimeException when it exceeds the supported data and time range. Below programs illustrate the plusNanos() method: Program 1: Java // Java program to demonstrate the plusNanos() method import java.time.OffsetDateTime; import java.time.ZonedDateTime; public class GFG { public static void main(String[] args) { // Parses the date1 OffsetDateTime date1 = OffsetDateTime .parse( "2018-12-12T13:30:30+05:00"); // Prints dates System.out.println("Date1: " + date1); // Subtracts the number of nanoseconds System.out.println("Date1 after adding nanoseconds: " + date1.plusNanos(-120)); } } Output: Date1: 2018-12-12T13:30:30+05:00 Date1 after adding nanoseconds: 2018-12-12T13:30:29.999999880+05:00 Program 2: Java // Java program to demonstrate the plusNanos() method import java.time.OffsetDateTime; import java.time.ZonedDateTime; public class GFG { public static void main(String[] args) { // Parses the date1 OffsetDateTime date1 = OffsetDateTime .parse( "2018-12-12T13:30:30+05:00"); // Prints dates System.out.println("Date1: " + date1); // Subtracts the number of nanoseconds System.out.println("Date1 after adding nanoseconds: " + date1.plusNanos(140)); } } Output: Date1: 2018-12-12T13:30:30+05:00 Date1 after adding nanoseconds: 2018-12-12T13:30:30.000000140+05:00 Reference: https://docs.oracle.com/javase/10/docs/api/java/time/OffsetDateTime.html#plusNanos(long) Comment More infoAdvertise with us Next Article OffsetDateTime plusNanos() method in Java with examples G gopaldave Follow Improve Article Tags : Java Java-Functions Java-time package Java-OffsetDateTime Practice Tags : Java Similar Reads OffsetTime plusNanos() method in Java with Examples The plusNanos() method of OffsetTime class used to add specified no of nanoseconds value to this OffsetTime and return the result as a OffsetTime object.
