I am working the Talend studio tool for data migration. Now I want to set the Current DateTime in the Date field.
I get the DateTime from this code TalendDate.getDate("yyyy-MM-dd HH:mm:ss") but it returns String type data. But I need Date type to insert.Is there any String to date (Sample insert is like this:1999-12-13 16:14:48) conversion is in the Talend Studio.
You can use routine function TalendDate.parseDate to convert a String to a Date.
TalendDate.parseDate("yyyy-MM-dd HH:mm:ss", yourStringData);
If you want the current datetime:
TalendDate.parseDate("yyyy-MM-dd HH:mm:ss", TalendDate.getDate("yyyy-MM-dd HH:mm:ss"));
But this makes no sense. Parsedate function is prepared to receive a string and convert it to a Date object. Date objects have it's own format, so you don't have to care how is stored, you need to change the Date format in the moment you show it, but not when you store it:
// this will produce a correct Date Object to store in your Date field
Date currentDate = TalendDate.getCurrentDate();
When you need to show/print it use SimpleDateFormat for example if you want to show 2015-07-05 16:00:00 you must do like this:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss);
System.out.println("My date formatted is: " + sdf.format(currentDate ));
its very simple with the use of DateFormat in java
public static void convert(String inputDate) throws ParseException {
DateFormat format = new SimpleDateFormat ("yyyy-MM-dd HH:mm:ss");
Date d = format.parse(inputDate); // example 1999-12-13 16:14:48
System.out.println(d);
}

I have a string like this 210115 I want to represent it as 21:01:15 any ideas?.
I tried using Gregorian calendar but it adds date to it which I don't want
SimpleDateFormat sdf = new SimpleDateFormat("HHmmss");
Date date = new Date();
try{
date = sdf.parse("210115");
}
catch(Exception e){
}
Calendar calendar = GregorianCalendar.getInstance();
calendar.setTime(date);
System.out.print(calendar.getTime());
Output is Thu Jan 01 21:01:15 UTC 1970 but what I want is just 21:01:15
Thanks.
To output a formatted date, you use another SimpleDateFormat object with a pattern with the format you want.
In this case, it sounds like you might want to use something like
SimpleDateFormat outputFormat = new SimpleDateFormat("HH:mm:ss");
System.out.println( outputFormat.format(date) );
So what you want is just a time, without time zone. I would recommend using the LocalTime class, which is exactly that, instead of the Date class.
LocalTime time = LocalTime.parse("210115", DateTimeFormatter.ofPattern("HHmmss"));
If u r getting the date string in "210115" this format and you want it in "21:01:15" format then why are you using date format.
Simply do string operation as:
String time="210115";
String newtime=time.substring(0,2)+":"+time.substring(2,4)+":"+time.substring(4,6);
System.out.println(newtime);
you will get the required format.21:01:15
I have very simple question - I read couple of threads here but I still do not understand how to get simple thing. I want to send string to method and get back joda date. I had no problem to build it up, but return format is 2015-03-11T17:13:09:000+01:00. How can I get desired (e.g. mmm-dd hh:mm) format back from below mentioned method (it mustto be a dateTime for sorting purposes on FX form)? I tried to gamble with another dateTimeFormatter but had no luck. Thank you very much in advance
public static DateTime stringToDateTime(String textDate) throws ParseException
{
DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss.SSS");
DateTime jodaTime = dateTimeFormatter.parseDateTime(textDate);
return jodaTime;
}
What do you mean by "return format"? "Format" term here could only be related to a string representation of a DateTime object. That means you should specify format of your input string (what you've already done in your code) - and a corresponding DateTime object will be created. After that you probably use toString() to check the results, but DateTime.toString() uses ISO8601 format (yyyy-MM-ddTHH:mm:ss.SSSZZ) according to JavaDoc - that gives you your 2015-03-11T17:13:09:000+01:00 result.
So to get it as desired you could try using toString(String pattern) method with format you need. But once again - it's just an output format to convert DateTime to String, it doesn't affect the datetime stored in your DateTime object.
I just use Calendar object so this is a possible way to do it:
static String stringToDateTime(String textDate) {
Calendar c = new GregorianCalendar();
// How you want the input to be formatted
DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
Date date = df.parse(textDate);
c.setTime(date);
} catch (ParseException e) {
e.printStackTrace();
}
// How do you want to print your date
df= new SimpleDateFormat("dd-MM-yy");
return df.format(c.getTime());
}
// input
String myDate = "2015-04-15 14:25:25";
System.out.println(stringToDateTime(myDate));
I want to store today's date in the format yyyy-mm-dd. before storing I have took today's date,formatted it and again parse the formatted string to date. It gives the output date in a different format other than what I want. How can i get the date, format it in 'yyyy-mm-dd'
and again convert it into date and want the output in the format 'yyyy-mm-dd'.Please find the below code and tell me where I am wrong
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
java.util.Date date = new java.util.Date();
java.util.Date date1;
String datestring=dateFormat.format(date);
try {
date1=dateFormat.parse(datestring);
System.out.print(date1);
} catch (ParseException ex) {
Logger.getLogger(accordcclass.class.getName()).log(Level.SEVERE, null, ex);
}
The output for the above code I get is
Thu Mar 07 00:00:00 GMT 2013. But I want the output as 2013-01-07
I had the same problem, this is what I did:
DateFormat inputDateFormat = new SimpleDateFormat("dd-MMM-yyyy HH:mm");
DateFormat outputDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");
System.out.println(outputDateFormat.format(inputDateFormat.parse("09-SEP-2013 10:00")));
That way I can parse the date in the original format and output it in the database compatible format.
There is the posibility of using PreparedStatement as someone mentiones before but I don't want to.
Don't use a Date object to print, use directly your datestring variable. Using a Date will call toString which will be formatted using the Locale.
Edit : Adding that if you want to store your Date variable with a format, it doesn't work that way. A Date doesn't hold a format, it just represents the time. How you show it in a GUI, console or anywhere else is where you need to specify a format if you want it to differ from the current Locale format.
You're using the DateFormat to format and reparse.
You don't need to re-parse. Simply use the DateFormat only to format.
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
java.util.Date date = new java.util.Date();
String datestring=dateFormat.format(date);
System.out.println( datestring );
I have My Database data in this format
18-NOV-10
I have to pass the same format into java.util.Date like this
Date date = new java.util.Date(dateformater);
so that the result of java.util.Date is like this 18-NOV-10
Is this possible ??
I tried this way
String strDate = "12-NOV-07";
SimpleDateFormat sdfSource = new SimpleDateFormat("dd-MMM-yy");
Date date = sdfSource.parse(strDate);
System.out.println(date);
But i am getting the result as "Mon Nov 12 00:00:00 IST 2007 " which i want it only
12-NOV-07"
You can use java.text.DateFormat (actually SimpleDateFormat) to get you where you want to go, but maybe you shouldn't be storing the dates as strings in your database. It will do output and parsing.
SimpleDateFormat sdf =
new SimpleDateFormat("DD-MMM-YY");
Date parsed = sdf.parse(dateString);
See http://javatechniques.com/blog/dateformat-and-simpledateformat-examples/
Once you get the Date, you can turn it into the format you want but it will be held in memory as a Date object. You can get it in the form you want using
String dateString = sdf.format(parsed);
As others have pointed out, you should probably store your dates as dates, not strings; nevertheless...
If you want to turn a Date back into a string in that format you can use the following:
DateFormat formatter = new SimpleDateFormat("dd-MMM-yy");
Date date = new Date();
String dateStr = formatter.format(date); // Gives "22-May-11"
If you need MAY instead of May, just use toUpperCase() on the resultant string.
DateFormat sdf = new SimpleDateFormat("dd-MMM-yy");
Date d = sdf.parse("18-NOV-10");
Try System.out.println(sdfSource.format(date).toUpperCase()); instead. The Date object will always have a time component to it; there is no way to "disable" that feature. What you can do instead is to ignore it in your calculations and display. If all Date objects you use are set to the same time of the day, then you can safely ignore the effect of the time component in your comparisons. If you look carefully, the time component of your Date object is set to midnight.
How can I take a string in a format such as: 2008-06-02 00:00:00.0 and convert it to: 02-Jun-2008?
Can I somehow take the original string, convert it to a Date object, then use a formatter to get the final output (rather than parsing the string myself)? Thanks!
You can use SimpleDateFormat to convert between a String and a Date object and vice versa based on a pattern. Click the API link, you'll see patterns being explained in detail. A 4-digit year can be represented with yyyy, a 3-character month abbreviation can be represented with MMM and so on.
First you need to parse the String of the first format into a Date object:
SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
Date date = sdf1.parse(inputString);
Then you need to format the Date into a String of the second format:
SimpleDateFormat sdf2 = new SimpleDateFormat("dd-MMM-yyyy", Locale.ENGLISH);
String outputString = sdf2.format(date);
Note that you need to take the Locale into account as well to get the month to be printed in English, else it will use the platform's default locale to translate the month.
Use 2 instances of SimpleDateFormat class. One for converting your input string to date and second to convert date back to string but in another format.
Here is an example of using SimpleDateFormat.
DateFormat startFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S");
DateFormat endFormat = new SimpleDateFormat("dd-MM-yyyy");
String outputString = null;
try {
Date date = startFormat.parse(inputString);
outputString = endFormat.format(date);
} catch(ParseException pe) {
throw new IllegalArgumentException(inputString + " is not properly formated.", pe);
}
You can definitely use SimpleDateFormat class like others have recommended.
Another suggestion if it applies in your case. If you are getting this data from a sql query you can also use to_char() method to format it in the query itself. For example: to_char(column_name,'DD-MON-YYYY')
