Duration plus() method in Java

Java 8Object Oriented ProgrammingProgramming

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

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 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));
