I am using jQuery Datepicker that is giving the date like 07/05/2015 this format.I am using simpledateformat to format this date.But always the SDF is converting it to the todays date.How to solve this ??
System.out.println("Activity IS : IS With Date");
SimpleDateFormat sdfOverTimeWithDate = new SimpleDateFormat("yyyy-MM-dd ");
Date startDate = ParamUtil.getDate(resourceRequest, "startDate", sdfOverTimeWithDate);
Date endDate = ParamUtil.getDate(resourceRequest, "endDate", sdfOverTimeWithDate);
int jobId= ParamUtil.getInteger(resourceRequest, "jobId");
System.out.println("jobId :"+jobId);
System.out.println("startDate :"+startDate);
System.out.println("endDate :"+endDate);
This statDate and endDate is giving todays's date only ,while the date i am pssing is in the format 07/05/2015.How to solve this ??somebody plaese help
You are passing wrong date format to SimpleDateFormat constructor. Try "dd/MM/yyyy" instead of "yyyy-MM-dd "
Is "07/05/2015" in July (US-Format) or May? Please clarify. If it is US-format (date expression starting with month number) then your solution is to use the pattern "MM/dd/yyyy" otherwise you should use the pattern "dd/MM/yyyy".
The pattern "yyyy-MM-dd " cannot be right due to two reasons:
a) It starts with a four-digit-year but your input begins with a two-digit-number.
b) It contains a trailing space.
Try to do it.
SimpleDateFormat sdfOverTimeWithDate = new SimpleDateFormat("yyyy-MM-dd");
try {
Date d = sdfOverTimeWithDate.parse("07/05/2015");
} catch (ParseException e) {
e.printStackTrace();
}

I am trying to format dates entered by my application user using SimpleDateFormat but I always get an error:
01/28/2014java.text.ParseException: Unparseable date: "01/28/2014"
The code I am using to format the date is as follows:
Date rDate, dDate;
String Date1 = request.getParameter("Date1");
String Date2 = request.getParameter("Date2");
//Here the date get display for example as 01/29/2014 (i.e. MM/DD/YYYY)
System.out.println("Date1:: "+ Date1);
System.out.println("Date2:: "+ Date2);
SimpleDateFormat parseRDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
SimpleDateFormat parseDDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
//#########Crashes in the next two lines#########...
rDate = (Date)parseRDate.parse(Date1);
dDate = (Date)parseDDate.parse(Date2);
} catch (ParseException e) {
e.printStackTrace();
}
Can someone please help me by telling me what I am doing wrong here?
Thanks for your time
You need to match the DateFormat pattern to your input String
SimpleDateFormat parseRDate = new SimpleDateFormat("MM/dd/yyyy");
Any idea how I can convert the format from MM/dd/YYYY to yyyy-MM-dd HH:mm:ss?
All you need to do is use a separate SimpleDateFormat instance for formatting
SimpleDateFormat output = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(output.format(date1));
As you say, Date1 is of the form MM/dd/yyyy... but you're trying to parse it with a format of yyyy-MM-dd HH:mm:ss.
The pattern you parse to the SimpleDateFormat constructor has to match the format of the data itself. (What did you think you were specifying in the constructor?)
Note that the code you've provided isn't doing and formatting at all - just parsing.
You should also work out which time zone you're interested in, and which Locale. Personally I think it's clearer to specify both of those explicitly - even if you want the system default ones.
(If you're doing any significant amount of date/time work, you should also consider using Joda Time, which is a much more pleasant date/time API. I'd also consider more useful exception handling, and following Java naming conventions...)
You specify the format yyyy-MM-dd HH:mm:ss in the constructor and then accept a completely different format (MM/dd/yyyy) as input. You need to make the actual format match the expected format.
Examine the following (for comparison):
Date rDate, dDate;
SimpleDateFormat parseRDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
SimpleDateFormat parseDDate = new SimpleDateFormat("MM/dd/yyyy");
try {
rDate = (Date)parseRDate.parse("2014-01-28 12:22:22");
dDate = (Date)parseDDate.parse("01/28/2014");
} catch (ParseException e) {
e.printStackTrace();
}
The string passed to the constructor is what tells SimpleDateFormat how to read the input you give it later.
I am trying to convert a String value that is stored in a database,for example "2012-01-20", to be in the format January 20, 2012.
I have seen some examples, but they are using Date which works with SimpleDateFormat.
As an example here is one way I tried but the "try" always fails and the result is null
DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
Date convertedDate=null;
try {
convertedDate = df.parse(datePlayed);
} catch(ParseException e){
e.printStackTrace();
}
In short, you're not using the right format for parsing. You need to use two DateFormat instances; one for parsing and one for formatting.
DateFormat parser = new SimpleDateFormat("yyyy-MM-dd");
DateFormat formatter = new SimpleDateFormat("MMM dd, yyyy");
Date convertedDate = parser.parse(datePlayed);
String output = formatter.format(convertedDate);
Date da = new Date();
SimpleDateFormat ft = new SimpleDateFormat("E, dd/MM/yyyy !");
System.out.println("Update : " + ft.format(da));
You can change your date style do you want at: E, dd/MM/yyyy !
Good luck !
If the Date is read from a Database, then store it as a java.sql.Date. You can then use SimpleDateFormat on it, maybe after converting to java.util.Date. From the ResultSet object, you can extract Dates.
If what you meant is that you are given a date in text that was extracted from a DB by someone else and you are stuck with it. Try using:
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
df.setLenient(true);
convertedDate = df.parse(datePlayed.trim() );
Also try displaying the text you are parsing before you parse to make sure the datePlayed value is what you expect.
With parseInt, an extra space before or after the data will cause an error, so calling trim() removes extra spaces.
How can I parse the following date in Java from its string representation to a java.util.Date?
2011-07-12T16:45:56
I tried the following:
private Date getDateTime(String aDateString) {
Date result = new java.util.Date();
SimpleDateFormat sf = new SimpleDateFormat("yyyy/MM/dd hh:mm:ss");
try
{
result = sf.parse(aDateString);
}
catch (Exception ex)
{
Log.e(this.getClass().getName(), "Unable to parse date: " + aDateString);
}
return result;
}
You are not using the right date format pattern. The year/month/day separators are clearly wrong, and you need a literal 'T'. Try this:
SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
For the record, this is an ISO 8601 combined date and time format.
Your date format pattern is incorrect. It should be yyyy-MM-dd'T'HH:mm:ss .
To parse a date like "2011-07-12T16:45:56" you need to use:-
SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Check the pattern you are feeding your SimpleDateFormat against the string you are feeding in.
See any potential discrepancies? I see 3.
I was trying to format a string into date.
For this I have written a code:-
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
System.out.println(sdf.format( cal.getTime() ));
This is fine..
But now I want to convert a string into a date formatted like above..
For example
String dt="2010-10-22";
And the output should be like this:-
2010-10-22T00:00:00
How do I do this?
String dt = "2010-10-22";
SimpleDateFormat sdfIn = new SimpleDateFormat("yyyy-MM-dd");
ParsePosition ps = new ParsePosition(0)
Date date = sdfIn.parse(dt, pos)
SimpleDateFormat sdfOut = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
System.out.println(sdfOut.format( date ));
This should do it for you, remember to wrap it in a try-catch block just in case.
DateFormat dt = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
try
{
Date today = dt.parse("2010-10-22T00:00:00");
System.out.println("Your Date = " + dt.format(today));
} catch (ParseException e)
{
//This parse operation may not be successful, in which case you should handle the ParseException that gets thrown.
//Black Magic Goes Here
}
If your input is going to be ISO, you could also look at using the Joda Time API, like so:
LocalDateTime localDateTime = new LocalDateTime("2010-10-22");
System.out.println("Formatted time: " + localDateTime.toString());
The same class you use for output formatting of dates can also be used to parse dates on input.
SimpleDateFormat reference
To use your example, to parse the sample date:
String dt = "2010-10-22";
SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd");
System.out.println(dateFormatter.parse(dt));
The fields that are not specified (ie. hour, minutes, etc) will be 0. So your same code can be used to format the date on output.
Date Format Example
Containing the Conversion of String Date object from one format to another
I am developing an application and I am stuck in converting string like 01/01/2037 01:00:00 AM
to Date
I used
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy hh.mm.ss.S aa")
Date d = dateFormat.parse(dateString);
but I get an error, any help will be appreciated.
you are converting this 01/01/2037 01:00:00 AM
therefore use
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss aa")
(more info in [documentation])1
then
Date date = dateFormat.parse("01/01/2037 01:00:00 AM");
keep in mind you have to wrap a try-catch around the parse method.
The problem is that the format you declared is nothing like the String you are trying to parse:
your String uses / to separate day, month, year while in your formatter you use -
your string separates hours with a dot, while in the formatter you use :
you do not have milliseconds in your string while you declared them in the formatter.
The following code should work:
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy hh.mm.ss.S aa");
try {
Date date = dateFormat.parse("01-01-2037 01.00.00.000 AM");
System.out.println(date);
} catch (ParseException e) {
e.printStackTrace();
