Duration minusDays() method in Java


An immutable copy of a duration where some days are removed from it can be obtained using the minusDays() method in the Duration class in Java. This method requires a single parameter i.e. the number of days to be subtracted and it returns the duration with the subtracted days.

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.ofDays(5);
      System.out.println("The duration is: " + d);
      System.out.println("A copy with 2 days removed from the duration is: " + d.minusDays(2));
   }
}

Output

The duration is: PT120H
A copy with 2 days removed from the duration is: PT72H

Now let us understand the above program.

First the duration is displayed. Then an immutable copy of the duration where 2 days are removed is obtained using the minusDays() method and this is displayed. A code snippet that demonstrates this is as follows −

Duration d = Duration.ofDays(5);
System.out.println("The duration is: " + d);
System.out.println("A copy with 2 days removed from the duration is: " + d.minusDays(2));
