What is the function of the getContentPane() in javax.swing?

I've visit a lot of tutorials about Java Swing, and i was wondering was the difference between adding a component using <ObjectJFame>.getContentPane().add(); or using <ObjectJFrame>.add(), and which is the best? (if there is a "better").

Read the documentation.

... As a conveniance add and its variants, remove and setLayout have been overridden to forward to the contentPane as necessary. This means you can write:

   frame.add(child);

...

So there should be no difference.

There is effectively no difference between getContentPane().add() and myJFrame.add(). I think it was back in the big Java 2 (JDK 1.5) revamp that adding directly to a top level UI component just forwarded to the underlying content pane.

Personally, I use getContentPane() for the sake of clarity, but whatever you do, be consistent about it so that you (including the future you) and other people) will know what's happening.

As long as I used the Swing library, I always add component using the second method. Actually, both functions do exactly the same thing.
