Problem converting date format in Java

Question

I have a string in the form MMM/dd/yyyy, ie. May/21/2010. Now I want to convert it to yyyyMMdd, ie. 20100521.

My code is:

public static void main(String[

You will need to apply the locale on SimpleDateFormat.

Here's a more shorter version:-

public String transformPrevDate(String date) {
    DateFormat oldFormat = new SimpleDateFormat("MMM/dd/yyyy", Locale.ENGLISH);
    DateFormat newFormat = new SimpleDateFormat("yyyyMMdd", Locale.ENGLISH);

    String formattedDate = "";

    try {
        formattedDate = newFormat.format(oldFormat.parse(date));
    }
    catch (ParseException e) {
        e.printStackTrace();
    }

    return formattedDate;
}

@Test
public void testTransformPrevDate() {
    assertEquals("20110113", transformPrevDate("Jan/13/2011"));
    assertEquals("20010203", transformPrevDate("Feb/03/2001"));
}
