Any model for a JTextArea should implement Document.
The default model for JTextArea is
javax.swing.text.PlainDocument.

Since it looks as though you are going to use
a very simple document structure, you might
want to take advantage of the default document's
"getParagraphElement(int pos)" method.  The
default model is line-based, so "pos" is the
line number.

Using this method of getting each line obviates
the need to calculate offsets, etc., and may
make you code more readable.

Yes, and no.  The editor may in fact be far too
complicated, with features which get in the way,
rather than help.  I often use the samples as springboards
for testing ideas, but just as often, I'll start with
a blank slate.  The latter approach lets me concentrate
on just the issues related to a specific component.
Reducing the number of side effects which a complex
example may introduce can potentially save time.
But there's no "this way is the best way" in this
matter.
