Java Calculate Number of Seconds Between two LocalTime

import java.time.LocalTime;
import java.time.temporal.ChronoUnit;

public class SecondsBetweenLocalTimExample {
    public static void main(String... args) {
        LocalTime startTime = LocalTime.of(10, 20, 30);
        LocalTime endTime = LocalTime.of(10, 30, 40);

        // Calculate Number of Seconds Between two LocalTime
        long numberOfSeconds = ChronoUnit.SECONDS.between(startTime, endTime);

        System.out.println(String.format("Number of seconds between %s and %s is %d", startTime, endTime, numberOfSeconds));
    }
}

Number of seconds between 10:20:30 and 10:30:40 is 610
