OR
Date date = Calendar.getInstance().getTime();
//
// Display a date in day, month, year format
//
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String today = formatter.format(date);
System.out.println("Today : " + today);
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);
