This is an assignment I have to do, basically I need to load the stockEnquiriesLog.txt file into the JTable here. My lecturer has given some hints, saying to just use some of the code from ReadFile.java and put it into loadInitialEnquiries(), then modifying to fit to the JTable. For the life of me, I can't figure it out. I've provided my code and the code to ReadFile.
This is the format of the .txt file:
<stock_enquiry>
Pink, Polly
020 8567 1234
PC Planet, Greenwich
13:45
I'd like help finding the number of printers we have got.
</stock_enquiry>
<stock_enquiry>
Red, Ryan
020 7465 9984
Digital Outlet, Gatwick
12:50
What is the top of the range digital camera we stock?
</stock_enquiry>
Thank you in advance for any assistance! And please excuse and stupid mistakes, I'm not too bright with Java...
