But I want it so that if the hour is over 12 hours or the minutes is over 59 then it will prompt to do it again. But right now it will just convert

问题 I also find myself facing the date problem today, I extracted the date from an xml file in string format but when I try to convert it into an int format I have an error. This is a part of my code : DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); Document doc = dBuilder.parse(inputFile); doc.getDocumentElement().normalize(); System.out.println("Root element :" + doc.getDocumentElement().getNodeName()); NodeList nList = doc.getElementsByTagName("top"); for (int j=0; j<= inputFile

问题 I'm getting unexpected output when running following code, DateFormat df = new SimpleDateFormat("YYYY-MM-dd"); Date date = df.parse("2012-06-23"); System.out.println(df.format(date)); Output : 2012-01-01 I'm expecting 2012-06-23 as output,what am i doing wrong ? 回答1: yyyy should be all lowercase, try that and see if it makes a difference... 回答2: Refer this Date & time in Java.

问题 I have a string stored in a database (example: Sat Jul 09 14:20:31 EDT 2011 ) This is stored as string (I am aware of SQLs date capabilities, but I'm not exploring that at this point). I want to pull this strong and compare it with the current time using the Date.compare function Date currentDate = new Date(); // the new current time value mCursor.getString(mCursor.getColumnIndex(TIMECOLUMN) //the old stored time value, pulled from the SQL database From the database I have a string value

问题 I could not find a correctly and clean working solution for my Date which is formatted like this: 201406082159 (8th of June, 21:59 here) Last I tried was this: SimpleDateFormat format2 = new SimpleDateFormat("YYYYMMDDHHMM", Locale.ENGLISH); Sadly it's not working and printing out Sun Dec 29 21:00:00 CET 2013 回答1: Minutes are set up by m not M Years are set up by y not Y Days (in month) are set up by d not D (in year) SimpleDateFormat format2 = new SimpleDateFormat("yyyyMMddHHmm", Locale

问题 I have this date: "Wed Dec 31 00:00:00 GMT-8 1969" But it cannot be parsed with this SimpleDateFormat: new SimpleDateFormat("EEE MMM dd hh:mm:ss zzz yyyy"); How do I specify the -8 in the format string? I have tried Z and X after reading the SDF docs, but to no avail. What should I use? 回答1: The use of -8 is in a non ISO standard format. Something like -0800 or -08:00 is expected. This is because the time offset can include half hours. You should run a preprocessing conversion on the string

问题 I am trying to get a format like this: 2013-06-15-17-45 I do the following in my code: Date d = new Date(); SimpleDateFormat ft = new SimpleDateFormat ("YYYY_MM_DD_HH_mm"); String fileName = "D:\\"+ft.format(d)+".csv"; But I don't get the DD right. It creates a file with a name like this: D:\\2013_12_340_13_53.csv 回答1: Capital "D" is day of year; lowercase "d" is day of month (SimpleDateFormat javadocs). Try: SimpleDateFormat ft = new SimpleDateFormat ("yyyy_MM_dd_HH_mm"); Also, capital "Y"
