final String OLD_FORMAT = "MMM dd, yyyy";
final String NEW_FORMAT = "yyyy/mm/dd";


String oldDateString = "Oct 16, 2013";
String newDateString;

SimpleDateFormat sdf = new SimpleDateFormat(OLD_FORMAT);
Date d = sdf.parse(oldDateString);
sdf.applyPattern(NEW_FORMAT);
newDateString = sdf.format(d);

Yes, you can use

new SimpleDateFormat("dd-MM-yy'T'hh:mm:ss'Z'");

Open in new window

or use the 'write-only language' of printf style formatting:
String s = String.format("%Td-%<Tm-%<TyT%<TTZ", d);
