in Java, how to parse a date string that contains a letter that does not represent a pattern?

String date ="2007-11-02T14:46:03+01:00";
String format = "yyyy-MM-ddTHH:mm:ssz";
new SimpleDateFormat(format).parse(date);

Exception in thread "main" java.lang.IllegalArgumentException: Illegal pattern character 'T'
    at java.text.SimpleDateFormat.compile(
    at java.text.SimpleDateFormat.initialize(
    at java.text.SimpleDateFormat.(
    at java.text.SimpleDateFormat.(

If you don't care about the time zone, you can use this method.

  public static Date convertToDate(String strDate) throws ParseException {
    Date date = null;
    if (strDate != null) {
      SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
      date = sdf.parse(strDate);
    return date;

I don't know if it's still useful for you, but I encounter with the same problem now, and after a little I come up with this.

The time you're trying to parse appears to be in ISO 8601 format. SimpleDateFormat unfortunately doesn't support all the same timezone specifiers as ISO 8601. If you want to be able to properly handle all the forms specified in the ISO, the best thing to do is use Joda time.

This example is straight out of the user guide:

DateTime dt = new DateTime("2004-12-13T21:39:45.618-08:00");

this doesn't work, +01:00 needs to be +0100 for joda to work.

@user - you're right, the ISO version doesn't like colons. Good news is you can pass the version with colons straight to the DateTime constructor.

String testDate = "2007-11-02T14:46:03+01:00";
DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssz");
Date date = formatter.parse(testDate);

You can try similar to the above

You can use following link for reference

You can try

String format = "yyyy-MM-dd'T'HH:mm:ssz";

Reference : from Javadoc

Text can be quoted using single quotes (') to avoid interpretation.

It works only if the string contains 'GMT'. Just like this : String date ="2007-11-02T14:46:03GMT+01:00";

@Bala R 2011-06-20 03:21:49

@Hendra that is true or it has to be String date ="2007-11-02T14:46:03+0100"; SimpleDateTime is is pretty limited in such situations an I guess if you(OP) don't have much control over the input, using libraries such as joda time would work out best.
