Yes - what does the .00Z represent? Hundredths of a second, plus Z for Zulu time? The Z is easy to handle if it's a constant. You need to put single quotes around it so it's not interpreted as a format code, since Z means RFC 822 time zone. Hundredths of a second is harder, since that's not represented by any ...

The correct format for the input depends on your locale. The default for the US locale looks like "Jan 1, 2003" so you might try that first. If you're located someplace else, your JDK (or OS) installation might not be set up for your actual locale, so you might try, e.g. DateFormat.getDateInstance(Locale.UK) to set the locale explicitly.

Both Date and Calendar represent real dates, that is, a point in time having a year, month, day and so on.

The parse() method takes a string, in a particular format and gets you a date object. This date object doesn't retain this format, it is merely a representation of the date.

77. Date Parsing Issue...    coderanch.com

The codes you use to specify the date format when you create a SimpleDateFormat object are case-sensitive. So "DD-MM-YYYY HH:MM:SS" doesn't mean what you think it means. Lookup the documentation for SimpleDateFormat for information on how to specify the format. Also, the "MM" you use for the months is not going to match three-letter month abbreviations like "Dec".

91. Not showing correct output when parsing the date    forums.oracle.com

Maybe that's because you made it silently catch parse exceptions. You should always log the errors that your program throws.

I'm going to whip out my crystal ball and guess that your next comment is going to be, "But I want the Date object to be in the MM/dd/yyyy format." If that is in fact where you're going with this, you need to know that Date objects don't have a format. They're just wrapper around a long.
