Duration ofNanos(long) method in Java with Examples
The ofNanos(long) method of Duration Class in java.time package is used to get a duration in a 1 nanoSecond format.
Syntax:
public static Duration ofNanos(long nanoSeconds)
Parameters: This method accepts a parameter nanoSeconds which is the number of nanoSeconds. It can be positive or negative.
Return Value: This method returns a Duration representing the time in 1 nanoSecond format.
Exception: This method throws ArithmeticException if the input nanoSeconds exceeds the capacity of Duration.
Below examples illustrate the Duration.ofNanos() method:
Example 1:
// Java code to illustrate ofNanos() method import java.time.Duration; public class GFG { public static void main(String[] args) { // input number of Nanos long noOfNanos = 1000000 ; // Duration using ofNanos() method Duration duration = Duration.ofNanos(noOfNanos); System.out.println(duration.getSeconds()); } } |
Output:
0
Example 2:
// Java code to illustrate ofNanos() method import java.time.Duration; public class GFG { public static void main(String[] args) { // input number of Nanos long noOfNanos = - 1000000 ; // Duration using ofNanos() method Duration duration = Duration.ofNanos(noOfNanos); System.out.println(duration.getSeconds()); } } |
Output:
-1
