Assigning the default value is redundant.

It could be `final` and could be initialised here rather than in main.

Could be declared `final`.

I'd rather keep them aligned as they were. I'm fine with reformatting, though. Both variants are acceptable and there's no strong preference to either in JDK code as far as I'm aware.

I believe the UI layout could be simplified by using `BorderLayout`, the default for `Frame`, where textArea is placed as `BorderLayout.CENTER` and button panel (with BoxLayout or FlowLayout) is placed as `BorderLayout.SOUTH`.

It's just a tip. The layout works; don't fix it if it's not broken.

You don't use action command, so it's somewhat redundant.

`pack()` is called twice.
