Good question, I've often wondered this myself!
Personally, I don't like to use anonymous inner classes for handling events. I generally handle events two ways:
1. Make the main class implement lots of interfaces and use action commands. eg
public class MyFrame extends JFrame implements ActionListener {
    public static final String CALC_BUTTON = "cb";
    public MyFrame() {
        super();
        JButton cButton = new JButton("Calculator");
        cButton.addActionListener(this);
        cButton.setActionCommand(CALC_BUTTON);
    public void actionPerformed(ActionEvent ae) {
         if (ae.getActionCommand().equals(CALC_BUTTON) {
             //do something
2. Subclass AbstractAction.
public class MyAction extends AbstractAction {
    //create a constructor specific to the goal
    public MyAction(/*Some arguments*/) {
        //set  variables
    public void actionPerformed(ActionEvent ae) {
         //handle the action
//and in the main class
JButton cButton = new JButton("Calculator");
cButton.setAction(new MyAction());I tend to use the first method more often, but if there's some specific kind of action, then I use the second method.
I'm interested to know what other people do though. :)
