ZonedDateTime plusNanos() method in Java with Examples

plusNanos() method of a ZonedDateTime class used to add the number of nanoseconds in this ZonedDateTime and return a copy of ZonedDateTime after addition.This method works on the instant time-line and adding one nanosecond return the time-line of one nanosecond later. Note that this method is a different approach to that used by days, months and years. This instance is immutable and unaffected by this method call.

Syntax:

public ZonedDateTime plusNanos(long nanoseconds)

Parameters: This method accepts a single parameter nanoseconds which represents the nanoseconds to add, It can be negative.

Return value: This method returns a ZonedDateTime based on this date-time with the nanoseconds added.

Exception: This method throws DateTimeException if the result exceeds the supported date range.

        ZonedDateTime zoneddatetime
            = ZonedDateTime.parse(
                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");
  
        // print instance
        System.out.println("ZonedDateTime before"
                           + " adding nanoseconds: "
                           + zoneddatetime);
  
        // add 30000000 nanoseconds
        ZonedDateTime returnvalue
            = zoneddatetime.plusNanos(30000000);
  
        // print result
        System.out.println("ZonedDateTime after "
                           + " adding nanoseconds: "
                           + returnvalue);
    }
}

Output:

ZonedDateTime before adding nanoseconds: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after adding nanoseconds: 2018-12-06T19:21:12.153+05:30[Asia/Calcutta]
