java Date和String转换总结

        //Date --->String
        DateFormat dft = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date dateNow = new Date(System.currentTimeMillis());
        String now = dft.format(dateNow);
        System.out.println(now);

       //String ---->Date 

       try {
            DateFormat dft = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");    
            Date startTime = dft.parse("2014-10-15 00:00:00");
            System.out.println(startTime.toString());
        } catch (ParseException e) {
            e.printStackTrace();
        }
