So I took your code and ran it and it works fine for me...

The problem, I think, you're having is that you're expecting a LocalDate object to maintain the format that you original parsed the object with, this is not how LocalDate works.

LocalDate is a representation of date or period in time, it is not a format.

LocalDate has a toString method which can be used to dump the value of the object, it, this is a internal format used by the object to provide a human readable representation.

To format the date, you need to use some kind of formater, that will take the pattern you want and a date value and return a String

For example, the following code...

SimpleDateFormat sdf = new SimpleDateFormat(pattern);
String date = "16-Mar-05";

DateTimeFormatter dtf = DateTimeFormat.forPattern("dd-MMM-yy");
LocalDate localDate2 = dtf.parseLocalDate(date);
System.out.println(localDate2 + "/" + dtf.print(localDate2));

//second way
LocalDate localDate3 = LocalDate.parse(date, DateTimeFormat.forPattern("dd-MMM-yy"));
System.out.println(localDate3 + "/" + dtf.print(localDate3));

//third way
DateTimeFormatter FORMATTER = DateTimeFormat.forPattern("dd-MMM-yy");
DateTime dateTime = FORMATTER.parseDateTime(date);
LocalDate localDate4 = dateTime.toLocalDate();
System.out.println(localDate4 + "/" + FORMATTER.print(localDate4));

Before you get upset about this, this is how Java Date works as well.
