Question

I am trying to convert the date from one format to Another

Input String – 2012-11-07-121603 (yyyy-MM-dd-HH-mm-ss)

Output String – 2012-11-07-12:16:03:000 (yyyy-MM-dd-HH:mm:ss:SSS)

ThreadSafeSimpleDateFormatUtil simpleDateFormat = new ThreadSafeSimpleDateFormatUtil(GenericConstants.DATE_FORMAT.YYYY_MM_DD_HH_MM_SS.toString());
final Date parsedDate = simpleDateFormat.parse(bulkCollectionTime);
simpleDateFormat = new ThreadSafeSimpleDateFormatUtil(GenericConstants.DATE_FORMAT.YYYY_MM_DD_HH_MM_SS_SSS.toString());
writeBean.setTimestamp(simpleDateFormat.format(parsedDate));

But it’s throwing below error:

java.text.ParseException: Unparseable date: "2012-11-07-121603"
    at java.text.DateFormat.parse(DateFormat.java:337)
    at com.belgacom.rosy.rebecca.utils.ThreadSafeSimpleDateFormatUtil.parse(ThreadSafeSimpleDateFormatUtil.java:39)

Answer 1

Looks like the input format should be without the “-” between hours, minutes and seconds:

2012-11-07-121603 (yyyy-MM-dd-HHmmss)
