I have the following java class, Date212. Originally it was meant to sort dates from a text file and output the sorted date in the format October 01, 2014. Which it does, but only for a text file imported to the overall java project. I need this class to be modified to do the same when the text file is selected to be opened from a drop down menu. Thank you for any help.

/*Establishes the names of the months
