How to calculate time difference between two time zones in Java

            /* ............... START ............... */
                

import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.Duration;

public class TimeZoneDifference {
    public static void main(String[] args) {
        // Define two time zones
        ZoneId zone1 = ZoneId.of("America/New_York"); // Example: New York
        ZoneId zone2 = ZoneId.of("Europe/London");   // Example: London

        // Get the current time in both time zones
        ZonedDateTime currentTimeZone1 = ZonedDateTime.now(zone1);
        ZonedDateTime currentTimeZone2 = ZonedDateTime.now(zone2);

        // Calculate the time difference
        Duration timeDifference = Duration.between(currentTimeZone1, currentTimeZone2);

        // Print the time difference
        System.out.println("Time difference between " + zone1 + " and " + zone2 + " is " +
             timeDifference.toHours() + " hours");
    }
}
