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
// 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
// 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
