iso date is not converted successfully into time with 12 hour format

Question

My code is as shown below:

private String getFormattedDate(String date){
    try {
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
        formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
        Date value = formatter.parse(date);

        SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MM HH:mm a");

        dateFormatter.setTimeZone(TimeZone.getDefault());
        date = dateFormatter.format(value);

    } catch (Exception e) {
        date = "00-00-0000 00:00";
    }

    return date;
}

Here what I want to do is , I want to convert 2018-03-19T19:24:41.396Z into the format 19-03 7:24 PM, but here it gives me the output 19-03 19:24 PM . Am I missing anything in my method because of which it is giving the false output?

note the returned date in the catch block doesn't have the same format than the date in the try block — jhamon, Mar 20 '18 at 11:07

SimpleDateFormat

Capital H Hour in day (0-23) and Small h Hour in am/pm (1-12)

Change this line

  SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MM HH:mm a");

to

  SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MM hh:mm a");

HH outputs hour in 0-23 format. You must use hh instead.

Try This

            SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
            formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
            Date value = formatter.parse(date);

            SimpleDateFormat dateFormatter = new SimpleDateFormat("dd-MM hh:mm a");

            dateFormatter.setTimeZone(TimeZone.getDefault());
            date = dateFormatter.format(value);
            System.out.println("Date :- "+date);
