Q's on Extending JButton

[foolishone]

I have this class entitled Cube and it extends JButton, but being new to programming, especially OOP, when I declare a Cube, how would I go about displaying a JButton, with the text/caption and all? Should I put anything special in the constructor?

In the object class:

public class Cube extends JButton
{
...
}


In the client:
Cube cube1 = new Cube();

I have used JButton's alot but have never extended them, and then tried to declare one.

Greatly Appreciated,
