感谢@Ole，我终于找到了解决方案并且可以使用.

Thanks @Ole , I finally found the solution and it works.

             Calendar calendar = Calendar.getInstance();;
             calendar.setTime(new Date("2017/02/02"));
             String[] ds = calendar.toString().split("=");
             String[] ds2 = ds[1].split(",");
             try {
                 Calendar cal = Calendar.getInstance();;
                 DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
                 cal.setTimeInMillis(Long.valueOf(ds2[0]));
                 System.out.println(formatter.format(cal.getTime()));
             }
             catch(Exception e) {

             }
