Android Simpledateformat, How to Use It

Android SimpleDateFormat, how to use it?

I assume you would like to reverse the date format?

SimpleDateFormat can be used for parsing and formatting.
You just need two formats, one that parses the string and the other that returns the desired print out:

SimpleDateFormat fmt = new SimpleDateFormat("yyyy-MM-dd");
Date date = fmt.parse(dateString);

SimpleDateFormat fmtOut = new SimpleDateFormat("dd-MM-yyyy");
return fmtOut.format(date);

Since Java 8:

DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd").withZone(ZoneOffset.UTC);
TemporalAccessor date = fmt.parse(dateString);
Instant time = Instant.from(date);

DateTimeFormatter fmtOut = DateTimeFormatter.ofPattern("dd-MM-yyyy").withZone(ZoneOffset.UTC);
return fmtOut.format(time);

            return df.format(Calendar.getInstance().getTime());
        }

SimpleDateFormat(dd/MM/yy kk:mm) showing time as 24:30 instead of 00:30

You should use the uppercase letter K

SimpleDateFormat("dd/MM/yy KK:mm", Locale.getDefault())

k: Hour in day (1-24)

K: Hour in am/pm (0-11)

is SimpleDateFormat not working in android 5.1.1?

Is locale set to an appropriate value? You can enforce US locale if that's an option for you, the following code works for me:

        SimpleDateFormat formatter = new SimpleDateFormat("MMMM dd yyyy hh:mm", Locale.US);
        Date x = formatter.parse("November 19 2016 21:54");
