Problem converting DateFormat to java?

Question

my input String: 2010-03-24T17: 28: 50.000Z

The output template is similar:

DateFormat formatter1 = new SimpleDateFormat("EEE. MMM. d. yyyy");

i will transform it as follows:

formatter1.format(new Date("2010-03-24T17:28:50.000Z"));//illegalArgumentException here the string "2010-03-24T17:28:50.000Z"

The output should be like this: Thu. March 24. Idea 2010

but I get an illegalArgumentException . Do not know why? any idea?

The problem in this part:

new Date("2010-03-24T17:28:50.000Z")

Apparently, it does not accept dates / times in this format.

You should not use this constructor in any case - create an appropriate formatter to parse this particular format, and then parse it with that.

Joda Time DateFormat . , Joda Time Android, ... .

: :

String inputText = "2010-03-24T17:28:50.000Z";
// "Z" appears not to be supported for some reason.
DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
inputFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
DateFormat outputFormat = new SimpleDateFormat("EEE. MMM. d. yyyy");
Date parsed = inputFormat.parse(inputText);
String outputText = outputFormat.format(parsed);

// Output is Wed. Mar. 24 2010 on my box
