I'd like to create a simple table game by Swing. I have a JFrame and a JPanel variable.

I want to add JButtons to this JPanel, but I'd like to create an own class.

I made a class that extends JButton (inheritence):

```
public class GameField extends JButton {...}

```

So I could add GameFields to the JPanel.

But I'd like to create GameFields by composition:

```
public class GameField{

    private JButton button;

}

```

But in this clase how I can add GameField to JPanel?
Can I solve this problem by compisition?
