Convert String " yyyy-MM-dd" to "E, MMM d"

Question

I'm trying to convert a String coming as "2014-11-04" from a Json Object, to "Tue,Nov 4" (I think it's "E, MMM d") but without sucess so far.

Here is the code of my last try:

private String convertDateString(String date) {

        SimpleDateFormat formatter = new SimpleDateFormat("E, MMM d");

        String convertedDate = formatter.format(date);


        return convertedDate;
    }

Thanks!

You can try as follows

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date date=formatter.parse("2014-11-04");
                             formatter = new SimpleDateFormat("E, MMM d");
System.out.println(formatter.format(date));

You needs to convert String to Date first, Since current String is not other format.

Follow SimpleDateFormat, next time it will help you.

private static String convertDateString(String date) {

        SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd");

        SimpleDateFormat formatter = new SimpleDateFormat("E, MMM d");

        String convertedDate = null;
        try {
            convertedDate = formatter.format(f.parse(date));
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return convertedDate;
    }

Input System.out.print(convertDateString("1990-10-11"));

Output Thu, Oct 11

To change date from one format to another,first convert original formatted String to date and then format it to target format. try this

private String convertDateString(String dateInString) {
    SimpleDateFormat originalFormat = new SimpleDateFormat("yyyy-MM-dd");
    SimpleDateFormat targetFormat = new SimpleDateFormat("E, MMM d");
    Date date = originalFormat.parse(dateInString);
    return targetFormat.format(date);
}

Convert String " yyyy-MM-dd" to "E, MMM d"
