Duration ofNanos() method in Java

The duration can be obtained in a one nano second format using the ofNanos() method in the Duration class in Java. This method requires a single parameter i.e. the number of nano seconds and it returns the duration in a one nano second format. If the capacity of the duration is exceeded, then the ArithmeticException is thrown.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.Duration;
public class Demo {
   public static void main(String[] args) {
      long nanoseconds = 1000000000;
      Duration duration = Duration.ofNanos(nanoseconds);
      System.out.println("The duration in seconds is: " + duration.getSeconds());
   }
}

Output

The duration in seconds is: 1

Now let us understand the above program.

The duration in a one nano second format is obtained using the ofNanos() method. Then this duration is printed in seconds using the getSeconds() method. A code snippet that demonstrates this is as follows −

long nanoseconds = 1000000000;
Duration duration = Duration.ofNanos(nanoseconds);
System.out.println("The duration in seconds is: " + duration.getSeconds());
