Change a String date into another String date

Question

I've got a String like this: 2013-04-19, and I want to change it into : April 19th 2013. I know there is some classes in Java like SimpleDateFormat, but I don't know what kind of function I should use. Maybe I need to choose the class Pattern? I need some help.

You can start reading about it here: http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html — home, Jan 13 '13 at 21:07
A quick look at any example for SimpleDateFormat will shoudl taht you need to `parse` and then `format` the String to a date and back to a String — Peter Lawrey, Jan 13 '13 at 21:07
Also, you will have to write a custom way to say `19th` as it's not standard in `SimpleDateFormat`. — Buhake Sindi, Jan 13 '13 at 21:08
Also; as always when dealing with dates - consider using (JodaTime)[http://joda-time.sourceforge.net/] — Peter Svensson, Jan 13 '13 at 21:14

Try the following, which should give you correct "th", "st", "rd" and "nd" for days.

public static String getDayOfMonthSuffix(final int n) {
        if (n >= 11 && n <= 13) {
            return "th";
        }
        switch (n % 10) {
            case 1:  return "st";
            case 2:  return "nd";
            case 3:  return "rd";
            default: return "th";
        }
    }

public static void main(String[] args) throws ParseException {
        Date d = new SimpleDateFormat("yyyy-MM-dd").parse("2013-04-19");

        int day = Integer.parseInt(new java.text.SimpleDateFormat("dd").format(d));
        SimpleDateFormat sdf = new SimpleDateFormat("MMMMM dd'" + getDayOfMonthSuffix(day) + "' yyyy");
        String s = sdf.format(d);

        System.out.println(s);
    }

Which will print April 19th 2013

(Day termination adapted from this post)

Thank you i will try it as soon as I can. – Tsunaze Jan 14 '13 at 08:59 — Tsunaze, Jan 14 '13 at 08:59
It will also display "13rd" and "12nd" – Colin Hebert Apr 17 '13 at 13:15 — Colin Hebert, Apr 17 '13 at 13:15

Try this:

String originalDate = "2013-04-19";
Date date = null;
try {
    date = new SimpleDateFormat("yyyy-MM-dd").parse(originalDate);
} catch (Exception e) {
}
String formattedDate = new SimpleDateFormat("MMMM dd yyyy").format(date);

Will not print the st, nd, rd, etc.

Just using parse method from SimpleDateFormat class try this:

new SimpleDateFormat("MMM dd YYYY").parse("2013-04-19");
