Introduction

The toMinutes() method allows you to convert a Duration instance to its total length in minutes. This is particularly useful when you need to work with durations in terms of minutes or when you need to compare durations.

toMinutes() Method Syntax

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

public long toMinutes()

Parameters:

• This method does not take any parameters.

Returns:

• A long representing the total number of minutes in the duration.

Throws:

• This method does not throw any exceptions.

Understanding toMinutes()

The toMinutes() method calculates the total number of minutes in the Duration instance by dividing the total duration in seconds by the number of seconds in a minute (i.e., 60). The result is the total length of the duration expressed in minutes.

Examples

Basic Usage

To demonstrate the basic usage of toMinutes(), we will convert a Duration instance to its total length in minutes.

Example

import java.time.Duration;

public class DurationToMinutesExample {
    public static void main(String[] args) {
        Duration duration = Duration.ofHours(2); // 2 hours
        long minutes = duration.toMinutes();

        System.out.println("Duration in minutes: " + minutes);
    }
}

Output:

Duration in minutes: 120

Converting Different Durations to Minutes

This example shows how to use the toMinutes() method to convert various durations to minutes.

Example

import java.time.Duration;

public class DurationToMinutesExample {
    public static void main(String[] args) {
        // 3 hours
        Duration duration1 = Duration.ofHours(3);
        long minutes1 = duration1.toMinutes();
        System.out.println("Duration 1 in minutes: " + minutes1);

        // 90 minutes (1.5 hours)
        Duration duration2 = Duration.ofMinutes(90);
        long minutes2 = duration2.toMinutes();
        System.out.println("Duration 2 in minutes: " + minutes2);

        // 5400 seconds (90 minutes)
        Duration duration3 = Duration.ofSeconds(5400);
        long minutes3 = duration3.toMinutes();
        System.out.println("Duration 3 in minutes: " + minutes3);
    }
}

Output:

Duration 1 in minutes: 180
Duration 2 in minutes: 90
Duration 3 in minutes: 90

Real-World Use Case

Converting Task Durations to Minutes

In real-world applications, the toMinutes() method can be used to convert task durations to minutes for scheduling or reporting purposes. For example, you might need to calculate the total number of minutes required to complete a series of tasks.

Example

import java.time.Duration;
import java.util.Arrays;
import java.util.List;

public class TaskDurationToMinutesExample {
    public static void main(String[] args) {
        List<Duration> taskDurations = Arrays.asList(
            Duration.ofMinutes(30),
            Duration.ofMinutes(45),
            Duration.ofMinutes(60)
        );

        long totalMinutes = taskDurations.stream()
                                         .mapToLong(Duration::toMinutes)
                                         .sum();

        System.out.println("Total duration in minutes: " + totalMinutes);
    }
}

Output:

Total duration in minutes: 135

Conclusion

The Duration.toMinutes() method is used to convert a Duration instance to its total length in minutes. This method is particularly useful for working with durations in terms of minutes and for performing time-based calculations or comparisons. By understanding and using this method, you can effectively manage and manipulate time-based data in your Java applications.
