Try something like this:

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm+s:SSSS");
Date date = format.parse(dateString);
format = new SimpleDateFormat("MM-dd-yyyy hh:mm a");
dateString = format.format(date);

Look java.text.SimpleDateFormat, you will need two instances: one for parsing, one for formatting.

You can do what Paulo and Walrus say, or just use String.substring (), since your syntax requirements are very simple.

You must create a Data object from your String -> use the appropriate class (e.g. SimpleDataFormat ), and then print it using a different format.
