SimpleDateFormat shows time in 24 hours even after using "hh" for hour

but the output of above parsed date is still in 24 hours format instead of 12 hours AM/PM.

You've parsed the value using hh, but the output is just what you get from calling Date.toString():

Converts this Date object to a String of the form:

dow mon dd hh:mm:ss zzz yyyy

where:
... hh is the hour of the day (00 through 23), as two decimal digits.

The fact that you parsed using a 12-hour time of day is irrelevant to the output of Date.toString(). A Date doesn't have any clue about format, or time zone, or calendar - it's just an instant in time. (Internally, a number of milliseconds since the Unix epoch.)

If you need to convert a Date to a String in a particular format, you should use DateFormat.format to do so.

I would also strongly discourage you from using a parsing format which uses hh but without an AM/PM designator - do you really only want to be able to represent values which occur in the morning?

Are you really sure that your input data is in 12-hour format? It seems unlikely to me - in particular, when the hour is zero-padded, that usually indicates that it's in a 24-hour format. The lack of an AM/PM specifier suggests that again.
