Duration multipliedBy() method in Java

An immutable copy of a duration where the required duration is multiplied by a value can be obtained using the method multipliedBy() in the Duration class in Java. This method requires a single parameter i.e. the value which is to be multiplied and it returns the immutable copy of the duration which is multiplied by a value.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.Duration;
import java.time.temporal.*;
public class Demo {
   public static void main(String[] args) {
      Duration d = Duration.ofHours(7);
      System.out.println("The duration is: " + d);
      System.out.println("Duration multiplied by 3 is: " + d.multipliedBy(3));
   }
}

Output

The duration is: PT7H
Duration multiplied by 3 is: PT21H

Now let us understand the above program.

First the duration is displayed. Then an immutable copy of the duration where 3 hours are multiplied to it is obtained using the multipliedBy() method and this is displayed. A code snippet that demonstrates this is as follows −

Duration d = Duration.ofHours(7);
System.out.println("The duration is: " + d);
System.out.println("Duration multiplied by 3 is: " + d.multipliedBy(3));
