Duration toMillis() method in Java


The value of a particular duration in the number of milliseconds can be obtained using the toMillis() method in the Duration class in Java. This method requires no parameters and it returns the duration in the number of milliseconds.

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) {
      Duration d = Duration.ofSeconds(1);
      System.out.println("The duration is: " + d);
      System.out.println("The number of milliseconds in the duration is: " + d.toMillis());
   }
}

Output

The duration is: PT1S
The number of milliseconds in the duration is: 1000

Now let us understand the above program.

First the duration is displayed. Then the value of that duration in the number of milliseconds is obtained using the toMillis() method and displayed. A code snippet that demonstrates this is as follows −

Duration d = Duration.ofSeconds(1);
System.out.println("The duration is: " + d);
System.out.println("The number of milliseconds in the duration is: " + d.toMillis());
