File displaying
I need to open a good-old plain text file. It has nothing fancy in it; just text. I'd like to do it in a JTextArea or something similar. How do I do that?

The easiest way is to use JTextComponent's read() method:
// (Error handling excluded)
JTextArea textArea = ...
File file = ...
FileReader reader = new FileReader(file);
textArea.read(reader, null);
