Event in UserInterface - organizing classes

Hello

This doubt ocurred while working on the design of a UI to a simple app. It's java.

The user interface is a JFrame that contains 3 JPanel objects. Two of these JPanel will have to listen to actions (buttons clickfor example) as well as the JFrame itself.

1) UI.java ---- JFrame, creates and lanches the UI, JMenu events
2) LeftPanel.java ---- JPanel, contains a JList, JList selections events
3) CenterPanel.java ----- JPanel, contains some text
4) RightPanel.java ----- JPanel, contains buttons, button click

How do you suggest the organization for this?

-> Using the main JPanel/JFrame to implement Action Listener

-> New class wich implements Action Listener
then in the JPanel an instance of that class is passed to the addActionListener method

-> there's also that syntax

button1.addActionListener ( new ActionListener() { ... } )

however that seams kind of strange.

-> Other ways?

Thanks

I would have each panel implement the listening interface that they are concerned with.
