Formatting a LocalDate in Java 8 using a specific Locale can be achieved like this: DateTimeFormatter.ofLocalizedDate(FormatStyle.SHORT).withLocale(myLocale).format(value); DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).withLocale(myLocale).format(value); DateTimeFormatter.ofLocalizedDate(FormatStyle.LONG).withLocale(myLocale).format(value); DateTimeFormatter.ofLocalizedDate(FormatStyle.FULL).withLocale(myLocale).format(value); Assuming value = LocalDate.now() this would result into: // myLocale = Locale.ENGLISH 6/30/16 Jun 30, 2016 June 30, 2016 Thursday, June 30, 2016 // myLocale =

Neither JPA nor Hibernate currently support the new date/time classes brought by JSR-310 in JDK8 (JPA ticket , Hibernate ticket ). Nonetheless, I'd like to code with the JDK8 date/time classes as they are finally well designed. In particular, I'm interested in java.time.Instant , not in full support for all java.time.* types, as all my entities will use this particular class (or so I think now, at least :-) One option is to write a type converter , as defined by JPA 2.1. However, our app server is JBoss EAP 6.3 which is JPA 2.0 but not 2.1 compatible, so this is out of the question for now.

I updated to the latest Android N sdk. The only thing I don't understand is why I cannot import java.time into my code? I thought Java8 is available through Android N. Then why didn't Google add java.time package? Maheshwar Ligade Android N is not supporting all the features of Java 8. Following features are only supported: Default and static interface methods Lambda expressions Repeatable annotations Reflection and language-related APIs: java.lang.FunctionalInterface java.lang.annotation.Repeatable java.lang.reflect.Method.isDefault() and Reflection APIs associated with repeatable annotations

How do I find out the last month and its year in java e.g. If today is 10th oct 2012, result should be Month = 9 and year = 2012, If today is 10th jan 2013, result should be Month = 12 and year = 2012 Gaim Your solution is here but instead of addition you need to use subtraction c.add(Calendar.MONTH, -1); Then you can call getter on the Calendar to acquire proper fields int month = c.get(Calendar.MONTH) + 1; // beware of month indexing from zero int year = c.get(Calendar.YEAR); Przemek java.time Using java.time framework built into Java 8: import java.time.LocalDate; LocalDate now = LocalDate

My input is a String representation of a date in the format "01-07-2015" for July 1, 2015. I'm trying to parse this into a java.time.LocalDate variable: final DateTimeFormatter DATE_FORMAT = DateTimeFormatter.ofPattern("dd-MM-YYYY"); final String input = "01-07-2015"; final LocalDate localDate = LocalDate.parse(input, DATE_FORMAT); Based on the DateTimeFormatter JavaDoc , I would expect this to work. However, I'm greeted with a very friendly and helpful message: Caused by: java.time.DateTimeException: Unable to obtain LocalDate from TemporalAccessor: {DayOfMonth=1, MonthOfYear=7, WeekBasedYear

Is there any reason to use Joda Time if I can use Java 8 Date and Time API ( java.time )? Should I use Java 8 Date and Time every time? The official statement of the author of Joda-time himself is to migrate as soon as Java-8 is available . See also this citation from the website : Note that Joda-Time is considered to be a largely “finished” project. No major enhancements are planned. If using Java SE 8, please migrate to java.time (JSR-310). So the short answer to your question is: YES (deprecated). However, keep in mind that some features like Joda- Interval or PeriodType or PeriodFormatter

Is there a usablility to get all dates between two dates in the new java.time API? Let's say I have this part of code: @Test public void testGenerateChartCalendarData() { LocalDate startDate = LocalDate.now(); LocalDate endDate = startDate.plusMonths(1); endDate = endDate.withDayOfMonth(endDate.lengthOfMonth()); } Now I need all dates between startDate and endDate . I was thinking to get the daysBetween of the two dates and iterate over: long daysBetween = ChronoUnit.DAYS.between(startDate, endDate); for(int i = 0; i <= daysBetween; i++){ startDate.plusDays(i); //...do the stuff with the new
