Thank you so much guys. It's working now!
Instead of BufferedReader, I used a String array created by .split() on a backslash n. I'm so happy I don't have to manually define the array size in Java beforehand!
To append text to a TextArea, I read the contents of it and concatenated that with a backslash n and the next line using .setText() as mentioned above.
I stripped out the sample code that I didn't need and got it working without those Super Dev errors.
