试试这个

try {
        SimpleDateFormat inputFormat = new SimpleDateFormat("dd-MM-yyyy");
        String date = "01-11-2014";
        Date d = inputFormat.parse(date);
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");

        System.out.println(formatter.format(d));
    } catch (ParseException e) {
        e.printStackTrace();
    }

如何将日期格式从dd-MM-yyyy更改为yyyy-mm-dd，我得到的结果为Thu Jan 02 00:00:00 IST 2014
