title: Java - having buttons displaying arrows
body: <p>I would like to have a buttons in Java which shows the arrows - like on the keyboard.
  So far I have this</p>
  
  <pre><code>JButton arrowUp = new JButton("^");
  JButton arrowDown = new JButton("v");
  JButton arrowLeft = new JButton("&lt;");
  JButton arrowRight = new JButton("&gt;");
  </code></pre>
  
  <p>It kinda works ... but does not look quite nice.</p>
  
  <p>Any help how to improve this is appreciated</p>
