Duration minus() method in Java

An immutable copy of a duration where the required duration is subtracted from it can be obtained using the minus() method in the Duration class in Java. This method requires two parameters i.e. the duration to be subtracted and the TemporalUnit of the duration. Also, it returns the duration with the required duration subtracted from it.

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(10);
      System.out.println("The duration is: " + d);
      System.out.println("Duration with 5 hours removed is: " + d.minus(5, ChronoUnit.HOURS));
   }
}

Output

The duration is: PT10H
Duration with 5 hours removed is: PT5H

Now let us understand the above program.

First the duration is displayed. Then an immutable copy of the duration where 5 hours are subtracted from it is obtained using the minus() method and this is displayed. A code snippet that demonstrates this is as follows −

Duration d = Duration.ofHours(10);
System.out.println("The duration is: " + d);
System.out.println("Duration with 5 hours removed is: " + d.minus(5, ChronoUnit.HOURS));
