title: How to set a line border around JTextArea?
body: <p>I have a <code>JTextArea</code> in my panel, but it is hard to distinguish it from the background.
  I tried <code>setBound()</code> but it doesn't really help.

  <p>(The textarea is next to 
  the 'DESCRIPTION') </p>
  
  <p>Is there any way to have a clear bound around it other than changing the colour of the background? Say having a line bound like what <code>JTextField</code> has(I put one next to 'EXPENSE' in my GUI).</p>
