Period Util
Description
The Date-Time API provides methods to compute the elapsed period between two dates and times.
We can use the until(end_date_or_time, time_unit) method on one of the
datetime-related classes, for example, LocalDate,
LocalTime, LocalDateTime, ZonedDateTime, etc.
Example
import java.time.LocalDate;
import java.time.LocalTime;
import java.time.Month;
import java.time.temporal.ChronoUnit;
//from www.ja v a2 s . c om
public class Main {
public static void main(String[] args) {
LocalDate ld1 = LocalDate.of(2014, Month.JANUARY, 7);
LocalDate ld2 = LocalDate.of(2014, Month.MAY, 18);
LocalTime lt1 = LocalTime.of(7, 0);
LocalTime lt2 = LocalTime.of(9, 30);
long days = ld1.until(ld2, ChronoUnit.DAYS);
System.out.println(days);
long hours = lt1.until(lt2, ChronoUnit.HOURS);
System.out.println(hours);
long minutes = lt1.until(lt2, ChronoUnit.MINUTES);
System.out.println(minutes);
}
}
The code above generates the following result.
