LocalTime plusNanos() method in Java with Examples

The plusNanos() method of LocalTime class used to add specified no of nanoseconds value to this LocalTime and return the result as a LocalTime object. This instant is immutable. The calculation wraps around midnight.

Syntax:

public LocalTime plusNanos(long nanosecondsToAdd)

Parameters: This method accepts a single parameter nanosecondsToAdd which is the value of nanoseconds to be added, it can be a negative value.



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

Below programs illustrate the plusNanos() method:

        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("19:34:50.63");
  
        // print LocalTime
        System.out.println("LocalTime before add: "
                           + time);
  
        // add 34000000 nanoseconds using plusNanos()
        LocalTime value = time.plusNanos(34000000);
  
        // print result
        System.out.println("LocalTime after add: "
                           + value);
    }
}
