ItemListemer and ActionListener...and others...how can they live together?

Question

Hi,
I want to have a couple of DropDown Menus, some Buttons and some Checkboxes in the same class....How can I do that knowing that my class needs to implement ItemListener and ActionListener ?
I've tried something like:
"public class extends Applet implements ItemListener implements ActionListener"
but not surprisingly it doesn't work....
and what if on top of that I want a MouseListener, a WindowListener or God knows what else...?
Thanks in advance for your help...
Tom

You need to read the basics about Swing events.
For starters, you do not implement listeners in your Applet class. Instead, you add new listeners to specific components that you want to listen on. For example, if you need to perform certain actions when a JComboBox's selection changes, you would do something like:
my_combo.addActionListener(  new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        System.out.println("selection changed to: " + my_combo.getSelectedItem());
});And for buttons:
my_button.addActionListener( new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        System.out.println("You clicked " + ((JButton) e.getSource()).getText() " button);
}MoustListener and other listeners can be similarily added. See JDK Documentation or Tutorials
