date

问题 I've been through every question and every third party library trying to figure out a way to do this where I don't have to manually map dates. I'm trying to get the week number of the current fiscal quarter. Each quarter starts on the 1st of either January, April, July or October. Given a date (string or object, it doesn't matter), I need to be able to calculate the week number of the fiscal quarter that it's in. To make matters a little more complicated, the Fiscal year starts in April. So

问题 I am trying to work with the date (timestamp to be precise) and getting into trouble. My requirement is below. I have a stage table where the data is stored as JSON in a Variant Column and the data looks like below in that column. { “message_body”: { “campus_code”: “TEST”, “campus_name”: “TEST”, “event_type”: “TEST”, “location_code”: “A00000”, “location_name”: “TEST”, “order”: { “credit_total”: 0, “app_version”: “1.0.9”, “asap”: 1, “order_datetime”: “2021-01-08 18:19:34” } “timezone_offset

问题 I want to convert dateStartString = “28/02/2018” in to Date and compare that converted date with today date. when i convert dateStartString the converted date is "2018-02-27 18:30:00 UTC" .why its output is wrong date? here is my code var dateStartString = "28/02/2018" let dateFormatter = DateFormatter() dateFormatter.dateFormat = "dd/MM/yyyy" guard let dateStartDate = dateFormatter.date(from: dateStartString) else { fatalError("ERROR: Date conversion failed due to mismatched format.") } let

问题 I am aware that parse() can be used for knowing if the valid date conforms to a specific format. But that throws exception in case of a failure. I wanted just to verify if the date is of a specific format. Especially I need a boolean result from this comparison. How to achieve that in Java? 回答1: I am wondering why nobody here knows following standard validation using ParsePosition . Programming based on exception logic is more or less evil. SimpleDateFormat sdf = new SimpleDateFormat("MM/dd

问题 I need to iterate through a range of dates. Not sure on how to take next day in for loop. I am using java.util.Date . So plusDays(1) cannot be used in the for loop for taking next date. Used date1 = new Date(date1.getTime() + (1000 * 60 * 60 * 24)) in for loop. But I don't think its a good idea to create objects by calling new each time in for loop. Please suggest a better way for taking next day in for loop. 回答1: tl;dr LocalDate.now().plusDays( 1 ) // Get tomorrow's date. Avoid legacy date

问题 There is an existing api which is having the below code : @GetMapping(value = "/getAmount") public long getAmount(){ Date d = new Date(); long amountFetchedFromDb = callToDatabase(d); return amountFetchedFromDb; } Now I need to change the functionality as below: @GetMapping(value = "/getAmount") public long getAmount(){ Date d = new Date(); <CALL TO A NEW REST API PASSING IT THE DATE d AND THE NEW API WILL MAKE THE DB CALL AND RETURN THE AMOUNT> return amount; } Now, I have created a new rest
