In this guide, you will learn about the Duration plus() method in Java programming and how to use it with an example.

1. Duration plus() Method Overview

Definition:

The Duration.plus() method is used to return a new Duration instance which is the sum of the current duration and the specified duration.

Syntax:

public Duration plus(Duration duration)

Parameters:

- duration: The duration to be added to the current duration. Should be of type Duration.

Key Points:

- The plus() method does not modify the original Duration instance but returns a new instance that represents the sum.

- The method can handle overflows, and if the resulting duration is too large to be represented, an ArithmeticException is thrown.

- Negative durations can be added using this method, which would result in subtracting the absolute value of the duration from the original.

2. Duration plus() Method Example

import java.time.Duration;

public class DurationPlusExample {
    public static void main(String[] args) {
        Duration initialDuration = Duration.ofHours(5);
        Duration additionalDuration = Duration.ofHours(2);

        // Add the durations together
        Duration resultDuration = initialDuration.plus(additionalDuration);

        // Print the resulting duration
        System.out.println("Resulting Duration: " + resultDuration);
    }
}

Output:

Resulting Duration: PT7H

Explanation:

In the provided example, we initially have a duration of 5 hours represented by initialDuration. 

We then have another duration of 2 hours represented by additionalDuration.

Using the plus() method, we add these two durations together, resulting in a new Duration instance of 7 hours. The output, "PT7H", is the standard ISO-8601 representation for a duration of 7 hours.
