date-parsing

I have a problem with parsing dates in a csv file. Have been looking for hours online and in books and testing, without finding the solution. Perhaps someone can help. The code works fine for reading a file with parsing just numbers. But when parsing a file with dates I get the following error message indicating the date format is not recognised: Problem parsing d="MNaN,268.5466377440347LNaN,117.78741865509761LNaN ... The file looks like this: date,value 11-11-13,582 12-11-13,860 13-11-13,940 Code: (js) function myFunction() { d3.csv('data/Date.csv', draw); } function draw(data) { "use strict"

Is there any way to convert a date String to LocalDateTime where the format "yyyy-MM-dd" ? If I try this: DateTimeFormatter DATEFORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd"); LocalDateTime ldt = LocalDateTime.parse(string, DATEFORMATTER); I got this exception: java.time.format.DateTimeParseException: Text '2017-03-13' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {},ISO resolved to 2017-03-13 of type java.time.format.Parsed at java.time.format.DateTimeFormatter.createError(DateTimeFormatter.java:1920) at java.time.format.DateTimeFormatter.parse

I have a scenario where I'm getting a date string as "46-05-24" (yy-mm-dd), and I need to re-format the date as "1946-05-24". The NSDateFormatter interprets the string as "2046-05-24". I'm using this code: let dateFormatter = NSDateFormatter() dateFormatter.dateFormat = "yy-mm-dd" let gmt : NSTimeZone = NSTimeZone(abbreviation: "GMT")! dateFormatter.timeZone = gmt let dateFromString = dateFormatter.dateFromString(date as String) dateFormatter.dateFormat = "yyyy-mm-dd" if dateFromString != nil{ let dateString = dateFormatter.stringFromDate(dateFromString!) print(dateString) } Is there something

I have a String with several dates, for example: [20-Jul-2012 5:11:36,670 UTC PM, 20-Jul-2012 5:11:36,683 UTC PM] How do I read this string and extract each date? I'm using the SimpleDateFormat class to create a regex. SimpleDateFormat format2 = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss,SSS z a"); I've tried : I've just did, to get the first one and it changes the format and the timezone: ParsePosition parsePos = new ParsePosition(1); SimpleDateFormat format2 = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss,SSS z a"); System.out.println(format2.parse(entry.getValue().toString(), parsePos)) ;

With the 'old', pre-Java 8 SimpleDateFormat I can do: new java.text.SimpleDateFormat("MMM yyyy", new java.util.Locale("es", "ES")).parse("Mayo 2017") to get the Date object of a date with Spanish month names. How can I achieve the same with Java 8 and DateTimeFormatter ? I tried: DateTimeFormatter.ofLocalizedDateTime(FormatStyle.FULL).withLocale(new Locale("es", "ES")).ofPattern("MMM yyyy").parse("Mayo 2017") but only get a java.time.format.DateTimeParseException . The call to ofLocalizedDateTime() can be removed, because in the end you call ofPattern() , creating another formatter with a

I am searching for a java library that can parse a string into a POJO without specifying the format. I have researched POjava . Is there anyother library which does similar thing? DateTime dateTime = DateTimeParser.parse("21/02/13"); //If unclear use the cultural information passed DateTime dateTime = DateTimeParser.parse("01/02/13", new Locale("en-us")); //Should also work with time zones DateTime dateTime = DateTimeParser.parse("2011/12/13T14:15:16+01:00"); I found the following links with the same problem Intelligent date / time parser for Java , but not very useful answers. Neither Joda or
