The plusNanos() method of Instant class adds nanoseconds value passed as parameter to this instant and return the result as an instant object. This returned Instant is immutable.
Syntax:
public Instant plusNanos(long nanosToAdd)
Parameters: This method accepts one parameter nanosToAdd which is nanoseconds to be added.
Returns: This method returns Instant, not null.
Exception: This method throws following exceptions:
- DateTimeException: if the result exceeds the maximum or minimum instant.
- ArithmeticException: if numeric overflow occurs.
Below programs illustrate the plusNanos() method:
Program 1:
// Java program to demonstrate// Instant.plusNanos() method import java.time.*; public class GFG { public static void main(String[] args) { // create a Instant object Instant instant = Instant.parse("2018-10-28T19:34:50.63Z"); // addition of 840000000 nanoseconds // means .84 seconds to this instant Instant returnedValue = instant.plusNanos(840000000); // print result System.out.println("Returned Instant: " + returnedValue); }} |
Output:
Returned Instant: 2018-10-28T19:34:51.470Z
Program 2:
// Java program to demonstrate// Instant.plusNanos() method import java.time.*; public class GFG { public static void main(String[] args) { // create a Instant object Instant instant = Instant.now(); // current Instant System.out.println("Current instant: " + instant); // addition of 430000000 nanoseconds // means .43 seconds to this instant Instant returnedValue = instant.plusNanos(430000000); // print result System.out.println("Returned Instant: " + returnedValue); }} |
Output:
Current instant: 2018-11-28T05:32:40.818Z Returned Instant: 2018-11-28T05:32:41.248Z
