The withNanos(long) method of Duration Class in java.time package is used to get an immutable copy of this duration with the specified amount of nano-seconds passed as the parameter.
Syntax:
public Duration withNanos(long amountOfNanos)
Parameters: This method accepts a parameter amountOfNanos which is the amount of nano-seconds.
Return Value: This method returns a Duration of the nano-seconds passed as the parameter.
Exception: This method throws DateTimeException if the nano-of-second is invalid.
Below examples illustrate the Duration.withNanos() method:
Example 1:
// Java code to illustrate withNanos() method import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Get the amount of nano-seconds
int amountOfNanos = 30000 ;
// Duration using parse() method
Duration duration
= Duration.parse( "P2DT3H4M" );
// Get the duration in nano-seconds
// using withNanos() method
System.out.println(duration
.withNanos(amountOfNanos));
}

Example 2:
// Java code to illustrate withNanos() method import java.time.Duration;
public class GFG {
public static void main(String[] args)
{
// Get the amount of nano-seconds
int amountOfNanos = 100000 ;
// Duration using ofHours() method
Duration duration = Duration.ofHours( 5 );
// Get the duration in nano-seconds
// using withNanos() method
System.out.println(duration
.withNanos(amountOfNanos));
}
