String date conversion error in Android

Question

I am developing an Android application, which has two EditText boxes and a button. In the first EditText box, I set the value 13/08/2014. On pressing the button, the value of the first EditText is converted into Date and then inserted into the second EditText.

I use the following code.

            SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
            DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
            String ss=todaysdate.getText().toString();
            Date d1 = df.parse(todaysdate.getText().toString());

What happens is, on pressing the button, value of ss and d1 becomes

ss = 13/08/2014
d1 = Thu Jan 08 00:00:00 IST 2015

See the change, it becomes January 8, 2015

Why is this, and what is the error?

what is the final format that you want? I assume that *13/08/2014* is the initial format — Illegal Argument, Aug 13 '14 at 11:59
String date1 = ""; Date date3 = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss") .parse(date1); DateFormat df6 = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss a"); System.out.println("output: " + "" + " " +date1+"::" +df6.format(date3)) — Yogesh Tatwal, Aug 13 '14 at 12:04
hmmm, so you have date in format `dd/MM/yyyy` and you wana parse it with format `MM/dd/yyyy` ? ... 13th month is january of next year ... so seems to me that the code works like a charm — Selvin, Aug 13 '14 at 12:04

it is not an error ... `df = new SimpleDateFormat("MM/dd/yyyy");` you see `MM/dd/yyyy`, again `MM/dd/yyyy` ... `ss = 13/08/2014` you have a `dd/MM/yyyy` format again `dd/MM/yyyy` and again `dd/MM/yyyy` ... `MM/dd/yyyy` != `dd/MM/yyyy` — Selvin, Aug 13 '14 at 12:13

Tell me Which is initial format and and Output Is it MM/dd/yyyy to yyyy-MM-dd'T'HH:mm:ss ??? — Yogesh Tatwal, Aug 13 '14 at 12:16
The initial fromat the I read from the EditText is dd/MM/yyyy and I need to get yyyy-MM-dd'T'HH:mm:ss at the end in string format — Roshan George, Aug 13 '14 at 12:18
One work around you can assign this value to calender and get time from calender in desirable form . — Yogesh Tatwal, Aug 13 '14 at 12:32

SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Date date = new Date();
String datestring= f.format(date).toString()

Like :-

  String date1 = "15/08/2014";
                Date date3 = new SimpleDateFormat("dd/MM/yyyy")
                        .parse(date1);
                Calendar newCalendar = Calendar.getInstance();
                newCalendar.setTime(date3);
                            SimpleDateFormat format1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");

                System.out.println(newCalendar.getTime());

                String formatted = format1.format(newCalendar.getTime());
                System.out.println(formatted);
