LocalDate date = LocalDate.parse(str, formatter) if we 2nd even we have changed in pattern also it is not working please workout with 2ndĭateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMMM Q, yyyy", Locale.ENGLISH) The following way can be used to parse the date in Java 8 without relying on Joda-Time: String str = "January 2nd, 2010" With Java 8 we get a new Date / Time API ( JSR 310). t(2009, Calendar.FEBRUARY, 25, now.get(Calendar.HOUR_OF_DAY), now.get(Calendar.MINUTE), now.get(Calendar.SECOND)) t(Calendar.SECOND,now.get(Calendar.SECOND)) t(Calendar.MINUTE,now.get(Calendar.MINUTE)) t(Calendar.HOUR_OF_DAY,now.get(Calendar.HOUR_OF_DAY)) Then you can manipulate that with something like: Calendar now = Calendar.getInstance() ("hod -> "+mydate.get(Calendar.HOUR_OF_DAY)) ("milli -> "+mydate.get(Calendar.MILLISECOND)) ("second -> "+mydate.get(Calendar.SECOND)) ("minute -> "+mydate.get(Calendar.MINUTE)) ("dow -> "+mydate.get(Calendar.DAY_OF_WEEK)) ("dom -> "+mydate.get(Calendar.DAY_OF_MONTH)) ("month -> "+mydate.get(Calendar.MONTH)) For example using your January date as input: Calendar mydate = new GregorianCalendar() ĭate thedate = new SimpleDateFormat("MMMM d, yyyy", Locale.ENGLISH).parse(mystring) To deal with date manipulation we use Date, Calendar, GregorianCalendar, and SimpleDateFormat. Here are some examples of valid SimpleDateFormat patterns to parse a given string to date:Īh yes the Java Date discussion, again. ![]() Note that the patterns are case sensitive and that text based patterns of four characters or more represent the full form otherwise a short or abbreviated form is used if available. If the locale doesn't match with the input string, then you would confusingly get a even though when the format pattern seems valid. If you omit it, then it will use the default locale which is not necessarily English as used in the month name of the input string. Note the importance of the explicit Locale argument. String string = "January 2, 2010" ĭateFormat format = new SimpleDateFormat("MMMM d, yyyy", Locale.ENGLISH) In case you're not on Java 8 yet, or are forced to use, then format the date using SimpleDateFormat using a format pattern matching the input string. Similarly, LocalDate#parse(text) parses an ISO date without the time component (see ISO_LOCAL_DATE), and ZonedDateTime#parse(text) parses an ISO date with an offset and time zone added (see ISO_ZONED_DATE_TIME). You could thus also define your own, if necessary.įor a particular input string format, you don't need to use an explicit DateTimeFormatter: a standard ISO 8601 date, like, can be parsed directly with LocalDateTime#parse(text) as it already uses the ISO_LOCAL_DATE_TIME formatter. This is possible because they are, on the contrary to SimpleDateFormat, thread safe. DateTimeFormatter.ofPattern("EEE, d MMM yyyy HH:mm:ss Z", Locale.ENGLISH), you could use DateTimeFormatter.RFC_1123_DATE_TIME. +0000 -08 -0830 -08:30 -083015 -08:30:15 ĭo note that it has several predefined formatters for the more popular patterns. Here's an extract of relevance from the javadoc, listing all available format patterns: And, if your format pattern happens to contain the time zone as well, then use ZonedDateTime#parse(text, formatter) instead. Note: if your format pattern happens to contain the time part as well, then use LocalDateTime#parse(text, formatter) instead of LocalDate#parse(text, formatter). ![]() LocalDate date = LocalDate.parse(string, formatter) "2010" is the 4-digit year, so use the yyyy pattern for it.ĭateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMMM d, yyyy", Locale.ENGLISH)."2" is the short day-of-month, so use the d pattern for it."January" is the full text month, so use the MMMM pattern for it.In your specific case of "January 2, 2010" as the input string: ![]() Simply format the date using DateTimeFormatter with a pattern matching the input string ( the tutorial is available here). Moreover, the whole class was de-facto deprecated (discommended) since introduction of java.time API in Java 8 (2014). That's the hard way, and those setter methods have been deprecated since Java 1.1 (1997).
