Duration plusHours() method in Java
An immutable copy of a duration where some hours are added to it can be obtained using the plusHours() method in the Duration class in Java. This method requires a single parameter i.e. the number of hours to be added and it returns the duration with the added hours.
A program that demonstrates this is given as follows −
Example
import java.time.Duration;
public class Demo {
public static void main(String[] args) {
Duration d = Duration.ofHours(1);
System.out.println("The duration is: " + d);
System.out.println("A copy with 2 hours added to the duration is: " + d.plusHours(2));
}
}Output
The duration is: PT1H A copy with 2 hours added to the duration is: PT3H
Now let us understand the above program.
First the duration is displayed. Then an immutable copy of the duration where 2 hours are added is obtained using the plusHours() method and this is displayed. A code snippet that demonstrates this is as follows −
Duration d = Duration.ofHours(1);
System.out.println("The duration is: " + d);
System.out.println("A copy with 2 hours added to the duration is: " + d.plusHours(2));
