# Duration ofMillis() method in Java

Java 8ProgrammingObject Oriented Programming

The duration can be obtained in a one millisecond format using the ofMillis() method in the Duration class in Java. This method requires a single parameter i.e. the number of milliseconds and it returns the duration in a one millisecond 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 milliseconds = 1000;
Duration duration = Duration.ofMillis(milliseconds);
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 millisecond format is obtained using the ofMillis() method. Then this duration is printed in seconds using the getSeconds() method. A code snippet that demonstrates this is as follows −

long milliseconds = 1000;
Duration duration = Duration.ofMillis(milliseconds);
System.out.println("The duration in seconds is: " + duration.getSeconds());
