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
