I haven't tried it with JTextArea but suppose it should work

Answer 2

Include the JTextArea inside a JScrollPane

JTextArea textArea = new JTextArea();
JScrollPane scrollArea = new JScrollPane(textArea);

This will dynamically change the text area based on if scrolling is needed or not

Answer 3

I wouldn't use JTextArea for anything except prototyping. It has the bitter functionality of notepad. But it's up to you.

I would use a JEditorPane or JTextPane. I know you can't size it based on character size but that's for the best. For word wrap, you can do setContentType("text/html"); and wrap the text in <'p><'/p> tags.

(Note you still use JScrollPane for scrolling. In fact, the scroll pane works for any component)
