Duration plusMinutes() method in Java

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

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.ofMinutes(5);
      System.out.println("The duration is: " + d);
      System.out.println("A copy with 3 minutes added to the duration is: " + d.plusMinutes(3));
   }
}

Output

The duration is: PT5M
A copy with 3 minutes added to the duration is: PT8M

Now let us understand the above program.

First the duration is displayed. Then an immutable copy of the duration where 3 minutes are added is obtained using the plusMinutes() method and this is displayed. A code snippet that demonstrates this is as follows −

Duration d = Duration.ofMinutes(5);
System.out.println("The duration is: " + d);
System.out.println("A copy with 3 minutes added to the duration is: " + d.plusMinutes(3));
