date

问题 I got a range date picker with two dates: start and end , where both can be empty. I would like to filter a table, where the entity has exact one date: date . So, here are some examples. I'd like to match. Imaging the date to match is the current date (17/07/2016). null - 17/07/2016 -> match 17/07/2016 - null -> match 17/07/2016 - 17/07/2016 -> match null - null -> match all Those are the edge cases in my opinion and the reason why I am struggling so much. Actually my code looks like:

问题 I'm trying to get a date from a string with multiple time zones, It works without any problems if the API returns zones with abbreviations like CST or UTC but it fails if it returns EET let timeString = "17:32 (EET)" let formatter = DateFormatter() formatter.dateFormat = "HH:mm (zzz)" let time = formatter.date(from: timeString) // return nil Any idea what is the issue might be?! 回答1: Probably because there is more than one timezone that matches the timezone abbreviation or the date formatter

问题 String s = "2020 Jun 31"; DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MMM dd"); LocalDate date = LocalDate.parse(s, formatter); System.out.println(date); Output: 2020-06-30 Why does 31 turn into 30 without any warnings or exceptions? 回答1: DateTimeFormatter has a ResolverStyle that affects how strict or lenient the parser should be with invalid date and time values. To get an exception in this case you need to set the resolver style to STRICT. You also need to use u (year)
