Incorrect date conversion by SimpleDateFormat

I am using SimpleDateFormat to convert the date from dd-MM-yyyy to yyyy-MM-dd but I does not display the year properly.I am trying to convert 18-5-2014 to 2014-05-18 but I am getting 3914-05-18.

 public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth)
 {

  Date selectedDate = new Date(year,monthOfYear, dayOfMonth);

  String strDate = null;

      SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd");

      strDate = dateFormatter.format(selectedDate);

      txtdeliverydate.setText(strDate);

  }

I suspect you didn't read the documentation for the (deprecated) Date constructor you're using:

Parameters:
year - the year minus 1900.
month - the month between 0-11.
date - the day of the month between 1-31.

Avoid using Date here. Either use a good date/time library like Joda Time, or use Calendar to set year/month/day values - even then, the month will be 0-based.

Also, your method is currently accepting year/month/day values... if you're actually just trying to do a conversion, you should be accepting a string and returning a string, e.g.

public static String convertDateFormat(String text) {
    TimeZone utc = TimeZone.getTimeZone("Etc/UTC");
    SimpleDateFormat parser = new SimpleDateFormat("dd-MM-yyyy", Locale.US);
    parser.setTimeZone(utc);
    Date date = parser.parse(text);

    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd", Locale.US);
    formatter.setTimeZone(utc);
    return formatter.format(date);
}
