LocalTime colonTime = LocalTime.of(17, 35, 50) DateTimeFormatter for TimeĭateTimeFormatter timeColonFormatter = DateTimeFormatter.ofPattern(timeColonPattern) This code snippet checks whether the date “ ” is one of a leap year, which it isn't. (om(europeanDateFormatter.parse("")).isLeapYear()) Likewise, custom formatting patterns can also be used to parse a String that holds a date: DateTimeFormatter europeanDateFormatter = DateTimeFormatter.ofPattern("dd.MM.yyyy") In our example, it would be “July.” A five-letter pattern, “MMMMM,” will make the formatter use the “narrow form.” In our case, “J” would be used. If we happen to use a four-letter pattern for the month, “MMMM,” then we'll get a “full form” representation. When we don't need the mentioned padding with zeroes, we can use a one-letter pattern “M,” which will show January as “1.” If the month number is less than 10, it will be padded with a zero. If we use a two-letter pattern for the month, we'll get a two-digit month representation. The number of letters in the pattern format is significant. This is an extract of the official Java documentation to DateTimeFormatter class. M/L month-of-year number/text 7 07 Jul July J Note that we used the ofLocalizedDateTime() method of DateTimeFormatter this time. ZonedDateTime zonedDateTime = ZonedDateTime.of(anotherSummerDay, anotherTime, ZoneId.of("Europe/Helsinki")) ĭateTimeFormatter.ofLocalizedDateTime(FormatStyle.FULL)ĭateTimeFormatter.ofLocalizedDateTime(FormatStyle.LONG)ĭateTimeFormatter.ofLocalizedDateTime(FormatStyle.MEDIUM)ĭateTimeFormatter.ofLocalizedDateTime(FormatStyle.SHORT) LocalTime anotherTime = LocalTime.of(13, 12, 45) To use FormatStyle with time, we have to use the ZonedDateTime instance, otherwise, a DateTimeException will be thrown: LocalDate anotherSummerDay = LocalDate.of(2016, 8, 23) We may also use predefined formatting styles for date and time. The output of these different formatting styles of the same date are: Tuesday, August 23, 2016 (DateTimeFormatter.ofLocalizedDate(FormatStyle.SHORT).format(anotherSummerDay)) (DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).format(anotherSummerDay)) (DateTimeFormatter.ofLocalizedDate(FormatStyle.LONG).format(anotherSummerDay)) (DateTimeFormatter.ofLocalizedDate(FormatStyle.FULL).format(anotherSummerDay)) package such cases, we may use enum (FULL, LONG, MEDIUM, SHORT) values with our DateTimeFormatter: LocalDate anotherSummerDay = LocalDate.of(2016, 8, 23) It’s better to create an utility class to handle conversion from Date To LocalDateTime and vice versa. In this section, let’s see how to convert LocalDateTime to Date in Java.Īdvertisements LocalDateTime now = LocalDateTime.now() If you are using a Java 9, there is an addition of an alternative method which simplifies it. ("Locale date time is Options 2:" + zoneDateTime2) ZonedDateTime zoneDateTime2 = currentDate ("Locale date time is :" + zoneDateTime) Let’s see how to convert Date to ZonedDateTime in Java Date currentDate = new Date() Locale date time is :T16:31:47.655 1.2 Date To ZonedDateTime Output Locale date time is :T16:31:47.655 ("Locale date time is Options 2:" + localDateTime2) LocalDateTime localDateTime2 = currentDate ("Locale date time is :" + localDateTime) 1.1 Date To LocalDateTime Date currentDate = new Date() We will also see the option to handle the ZonedDateTime. In this section, let’s see how to convert Date to LocalDateTime with Java. Java 8 introduces a new API to work with date and time.
