how to get the minute difference between two localdatetime variables in java of the pattern dd.mm.yyyy hh:mm

antwort:
To calculate the minute difference between two LocalDateTime variables in Java with a pattern dd.MM.yyyy HH:mm, you can follow these steps:

Parse the date-time strings into LocalDateTime objects using DateTimeFormatter.
Use Duration.between() to get the difference between the two LocalDateTime objects.
Retrieve the difference in minutes from the Duration.
Here’s an example of how to implement this:

java
Code kopieren
import java.time.Duration;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class MinuteDifferenceExample {
    public static void main(String[] args) {
        // Define the date format
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd.MM.yyyy HH:mm");

        // Parse the two LocalDateTime objects
        LocalDateTime dateTime1 = LocalDateTime.parse("06.10.2024 14:30", formatter);
        LocalDateTime dateTime2 = LocalDateTime.parse("06.10.2024 16:45", formatter);

        // Calculate the duration between the two
        Duration duration = Duration.between(dateTime1, dateTime2);

        // Get the difference in minutes
        long minutesDifference = duration.toMinutes();

        System.out.println("Minute difference: " + minutesDifference);
    }
}
Explanation:
DateTimeFormatter: This formats the LocalDateTime according to the provided pattern (dd.MM.yyyy HH:mm).
LocalDateTime.parse(): Converts the date-time strings to LocalDateTime objects using the specified formatter.
Duration.between(): Computes the duration between the two LocalDateTime instances.
duration.toMinutes(): Extracts the total minutes of difference.
This will print the minute difference between the two date-time values.
