My JTable contains the contents of a user's hard drive with one column displaying a short file extension type description. My method that searches the Hashtable for the file extension and retrieves the description determines the file extension by the indexOf() method like so:
there are instances however where there are 2 periods in the file name including before the file extension so the indexOf() method naturally stops at the first period. Example: intel.com.DAT
in the above example my method fails to detect .DAT as the file extension.
Is there a way to detect if there are 2 or more periods in a String.
