Good afternoon everyone, I have probably a real simple question but I am not very clear on how to do it. I need to format a date that is comming into my program as "200404271127" And I need take that date and make it into this format 04/27/2004. Any ideas? Thanks

String dateString = ....
SimpleDateFormat dfIn = new SimpleDateFormat("yyyyMMddHHmm");
Date myDate = dfIn.parseDate(dateString);
SimpleDateFormat dfOut = new SimpleDateFormat("MM/dd/yyyy");
String newFormattedString = dfOut.format(myDate);

Of course, if the format is fixed then the substring approach would work as well:
String dateString = ....
StringBuffer strbuf = new StringBuffer();
strbuf.append(dateString.substring(4, 6));
strbuf.append('/');
strbuf.append(dateString.substring(6, 8));
strbuf.append('/');
strbuf.append(dateString.substring(0, 4));
String newlyFormattedDateString = strbuf.toString();

> Date myDate = dfIn.parseDate(dateString);

that should be

Date myDate = dfIn.parse(dateString);
