IsSameHour(zonedTimestamp, zonedTimestampToCompare), is(true)) 5. We can see that two ZonedDateTime objects are actually happening within the same hour, even if their local times are different (8:30 and 14:00, respectively): ZonedDateTime zonedTimestamp = isEqual(uncatedTo(HOURS)) įinally, in a similar way, we can check if two ZonedDateTime instances happen within the same hour: public static boolean isSameHour(ZonedDateTime zonedTimestamp, Thirdly, we can implement a comparison at the level of an hour: public static boolean isSameHour(LocalDateTime timestamp, The truncatedTo(TemporalUnit) method truncates a date on the given level, which in our example is a day. Secondly, we'll check if two instances of LocalDateTime are on the same day: public static boolean isSameDay(LocalDateTime timestamp, Return timestamp.toLocalDate().isEqual(localDateToCompare)

The bulk of the text is devoted to code snippets that display. This document provides an introduction to the Joda-Time API for the average user, not for the would-be API developer. Many, perhaps most, applications will never need to see whats below the surface. Public static boolean isSameDay(LocalDateTime timestamp, Joda-Time is like an iceberg, 9/10ths of it is invisible to user-code. They have different LocalDateTime and ZoneId fields internally: assertThat(timeInNewYork.equals(timeInBerlin), is(false)) ĪssertThat(pareTo(timeInBerlin), is(-1)) 4. ZonedDateTime.of(2019, 8, 10, 14, 0, 0, 0, ZoneId.of('Europe/Berlin')) ĪssertThat(timeInNewYork.isAfter(timeInBerlin), is(false)) ĪssertThat(timeInNewYork.isBefore(timeInBerlin), is(false)) ĪssertThat(timeInNewYork.isEqual(timeInBerlin), is(true)) Īlthough both ZonedDateTime instances represent the same moment in time, they do not represent equal Java objects. Let's compare 8:00 local time in New York and 14:00 local time in Berlin, on the same day: ZonedDateTime timeInNewYork = Likewise, we can use the same methods for comparing two ZonedDateTime instances. Additionally, equals() and compareTo() can be used in a similar fashion as described for LocalDate. The result of this method can be a negative period if the end is before the start. Note that the start date is included, but the end date is excluded. The between () method returns a Period consisting of the number of years, months, and days between two dates. Similarly to LocalDate, we're comparing two LocalDateTime instances with the methods isAfter(), isBefore() and isEqual(). Period.between () for Difference in Days, Months and Years.
