I have a string 10-MAR-1998 14:47 which I need to convert to DateTime object of a specified format. For example: (dd-MMM-yyyy HH:mm GMT) in java.

  • Your question is unclear - when you say "DateTime object", do you mean a joda DateTime? If not what class are you referring to? Also a date/time object generally represents a point in time but doesn't have a format - you format it when you need to show it to a user using a formatter. – assylias Apr 04 '16 at 09:04
  • There might be about thousands of java date format questions out there in SO. I cannot imagine, you didn't find anything. – mad_manny Apr 04 '16 at 09:08

DateTimeFormatter

and 

SimpleDateFormat

are your friends, my friend. The only question is, is the date time of the input string also in GMT?

If it is, then:

String myString = "10-MAR-1998 14:47";
DateFormat format = new SimpleDateFormat("d-M-y H:m");
Date date = format.parse(myString);

should do the trick ;)

You could try SimpleDateFormat

In your case you would have

String str = "10-MAR-1998 14:47";
DateFormat df = new SimpleDateFormat("dd-MMM-yyyy hh:mm");
Date date = df.parse(str);

You can also go back from date to string with the specified format like this :

String dateStr = df.format(df.parse(date));

I know that the library Joda Time

handles quite well date conversion. But you would have to add a dependency to your project and if it's the only thing you need for date conversion right now I would suggest sticking with SimpleDateFormat.
