Java Duration toMinutes()

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

1. Duration toMinutes() Method Overview


The Duration.toMinutes() method is employed to obtain the total number of minutes represented by this duration, including both the whole hours and minutes.


public long toMinutes()


- None.

Key Points:

- The method returns the total count of minutes in the Duration.

- This includes both the whole hours (converted to minutes) and any additional minutes.

- A negative Duration will result in a negative returned value.

- This method can be useful for operations that require durations in minute granularity or when displaying the duration in minutes.

2. Duration toMinutes() Method Example

import java.time.Duration;

public class DurationToMinutesExample {
    public static void main(String[] args) {
        Duration duration1 = Duration.ofHours(2).plusMinutes(30); // 2 hours and 30 minutes
        Duration duration2 = Duration.ofHours(-1).minusMinutes(15); // -1 hour and 15 minutes

        // Convert durations to minutes
        long minutes1 = duration1.toMinutes();
        long minutes2 = duration2.toMinutes();

        // Print the minutes
        System.out.println("Duration1 in minutes: " + minutes1);
        System.out.println("Duration2 in minutes: " + minutes2);


Duration1 in minutes: 150
Duration2 in minutes: -75


In the example, duration1 is constructed with a total of 2 hours and 30 minutes. When toMinutes() is called, it returns 150 which is the total minutes (120 minutes from the 2 hours and 30 additional minutes).

For duration2, which is -1 hour and 15 minutes, the toMinutes() method gives -75 as the result. This is because 1 hour has 60 minutes, so the total becomes -60 - 15 = -75 minutes.
