Introduction

The plusMinutes() method allows you to add a specified number of minutes to an existing Duration instance. This is particularly useful when you need to adjust a duration by a specific number of minutes, such as extending an interval or adding additional minutes to a task.

plusMinutes() Method Syntax

The syntax for the plusMinutes() method is as follows:

public Duration plusMinutes(long minutesToAdd)

Parameters:

• minutesToAdd: The number of minutes to add, which can be positive or negative.

Returns:

• A Duration that is the result of adding the specified number of minutes to the original duration.

Throws:

• This method does not throw any exceptions.

Understanding plusMinutes()

The plusMinutes() method creates a new Duration instance by adding the specified number of minutes to the original duration. The result is a new Duration object representing the adjusted time span.

Examples

Basic Usage

To demonstrate the basic usage of plusMinutes(), we will add a specified number of minutes to an existing Duration instance.

Example

import java.time.Duration;

public class DurationPlusMinutesExample {
    public static void main(String[] args) {
        Duration originalDuration = Duration.ofHours(1);
        Duration addedDuration = originalDuration.plusMinutes(30);

        System.out.println("Original duration: " + originalDuration);
        System.out.println("Added duration: " + addedDuration);
    }
}

Output:

Original duration: PT1H
Added duration: PT1H30M

Handling Negative and Large Minute Values

This example shows how to use plusMinutes() to handle negative and large minute values.

Example

import java.time.Duration;

public class NegativeAndLargeMinutesExample {
    public static void main(String[] args) {
        Duration duration = Duration.ofHours(1);

        // Add a negative number of minutes
        Duration negativeResult = duration.plusMinutes(-15);
        System.out.println("After adding -15 minutes: " + negativeResult);

        // Add a large number of minutes
        Duration largeResult = duration.plusMinutes(90);
        System.out.println("After adding 90 minutes: " + largeResult);
    }
}

Output:

After adding -15 minutes: PT45M
After adding 90 minutes: PT2H30M

Real-World Use Case

Extending Task Durations

In real-world applications, the plusMinutes() method can be used to extend task durations, such as adding additional minutes to a task or extending a deadline by a certain number of minutes.

Example

import java.time.Duration;

public class TaskDurationExtensionExample {
    public static void main(String[] args) {
        Duration originalDuration = Duration.ofMinutes(90);
        long extraMinutes = 30;

        // Extend the original duration by adding extra minutes
        Duration extendedDuration = originalDuration.plusMinutes(extraMinutes);

        System.out.println("Original duration: " + originalDuration);
        System.out.println("Extended duration: " + extendedDuration);
    }
}

Output:

Original duration: PT1H30M
Extended duration: PT2H

Conclusion

The Duration.plusMinutes() method is used to add a specified number of minutes to a Duration instance. This method is particularly useful for adjusting durations by a specific number of minutes. By understanding and using this method, you can effectively manage and manipulate time-based data in your Java applications.
