Duration plus() method in Java
An immutable copy of a duration where the required duration is added to it can be obtained using the plus() method in the Duration class in Java. This method requires two parameters i.e. the duration to be added and the TemporalUnit of the duration. Also, it returns the duration with the required duration added to it.
A program that demonstrates this is given as follows −
Example
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 added is: " + d.plus(5, ChronoUnit.HOURS));
}
}Output
The duration is: PT10H Duration with 5 hours added is: PT15H
Now let us understand the above program.
First the duration is displayed. Then an immutable copy of the duration where 5 hours are added to it is obtained using the plus() 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 added is: " + d.plus(5, ChronoUnit.HOURS));
