问题 I want to get a date as string and a language tag and based on that to parse the string by the locale format. This is what I've done so far: public static String formatDateByLocale(String date, String languageTag) { Locale locale = Locale.forLanguageTag(languageTag); String datePattern = DateTimeFormatterBuilder.getLocalizedDateTimePattern(FormatStyle.LONG, FormatStyle.LONG, Chronology.ofLocale(locale), locale); DateTimeFormatter targetFormat = DateTimeFormatter.ofPattern(datePattern)

问题 Clarification A: Since this is an SSL question, I hope I can lower the obvious security red flags and potentially save the time of our resident SSL security experts, by stating the following: This SSL communication is between a test machine and a product deployment that is not ready for final security work (ie: after initial testing is complete, a security team will fix all the certificates, ports, settings, etc...) At this point, both test client and test target machines are far less

问题 This question already has answers here : Is java.time failing to parse fraction-of-second? (3 answers) Closed 8 months ago . Running this gives me the following error, what am I missing ? public static void main(String[] args) { DateTimeFormatter _timestampFomatGMT = DateTimeFormatter.ofPattern("yyyyMMddHHmmssSSS"); LocalDateTime localDateTime = LocalDateTime.parse("20200331094118137",_timestampFomatGMT); System.out.println(localDateTime); } Gives me the following exception. What am I missing

问题 I develop a Java application using Maven 3 and Podman 1.8.0. I understand that Podman provide a Docker compatible REST API. Java integration test use TestContainer framework. TestContainer is not able to connect to Podman REST API. I have the same problem with the python application use to test Podman. Is it a problem with user account? Does Podman 1.8 release support REST API yet? Thx. 来源： https://stackoverflow.com/questions/60476215/access-podman-rest-api-from-testcontainer

问题 I'm reviewing some old code, where I'm grouping elements. It looks more or less like this: Map<Long,List<Items>> groupedItems = ... for (long groupid : groups){ for (Item item :items){ if (isGroupAccepting(item.getId(),groupid) || groupid == item.getGroup()) { groupedItems.get(groupid).add(item); } } } I planned to replace it using grouping from stream API, but I'm stuck. It works fine for my second condition, but how to deal with the first one, where item should be added to every group which

问题 *To preface, I posted a similar question but this time, the output I want is going to be different. Suppose we have a person named Bob, and he has a list of integers he wrote down: bobList = [10, 25, 30, 50] Say there are 3 other lists of random integers that was generated by a system and put into 1 master list: list1 = [1, 10, 20, 25, 33, 55] list2 = [2, 3, 5, 6, 9, 30] list3 = [25, 30, 50, 100] List<List<Integer>> masterList = new ArrayList<>() masterList.add(list1) masterList.add(list2)
