Instant plusNanos() method in Java with Examples
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
