After line 223, output local_stock. Is it what you expect?
still can not get it to read my text file. have tried he full file path, putting the file into the eclipse project folder
How do you know it's not reading the text file? We're not psychic. We can't see your screen, we can't see your error messages, all we have is what you tell us; so tell us how you know it's not reading the text file.

Cannot open file StockData, now exiting from program

This is the message I get when I run my program. Which is what is supposed to do if the wrong file or no file is read.
Doesn't seem to be the code, check the file and spelling, including case, spaces and file extension.
And read permissions.
