// BAD: Duplicate anonymous classes:
button1.addActionListener(new ActionListener() {
public void actionPerfored(ActionEvent e)
{
for (ActionListener listener: listeners)
listeners.actionPerformed(e);
}
});
button2.addActionListener(new ActionListener() {
public void actionPerfored(ActionEvent e)
{
for (ActionListener listener: listeners)
listeners.actionPerformed(e);
}
});
// ... and so on.
// GOOD: Better solution:
class MultiplexingListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
for (ActionListener listener : listeners)
listener.actionPerformed(e);
}
}
button1.addActionListener(new MultiplexingListener());
button2.addActionListener(new MultiplexingListener());
// ... and so on.
