 public String parseDate(String thedate){
    String strReturn = "";
    SimpleDateFormat bartDateFormat =  new SimpleDateFormat("yyyyMMdd");
    String dateStringToParse = thedate;
    try {
      Date date = bartDateFormat.parse(dateStringToParse);
      SimpleDateFormat bartDateFormat2 = new SimpleDateFormat("yyyy-MM-dd EEEE");
      strReturn = bartDateFormat2.format(date);
    }catch (Exception ex) {
      ex.printStackTrace();
    }
    return strReturn;
  } 
  public static void main(String[] args) {
  Untitled1 test1 = new Untitled1();
  System.out.println(test1.parseDate("20040702"));
