## 20.2 java.awt.event.ActionListener (JDK 1.1)

###

This interface defines the method that an object must implement to "listen" for action events on AWT components. When an `ActionEvent` occurs, an AWT component notifies its registered `ActionListener` objects by invoking their `actionPerformed()` methods.

    public abstract interface ActionListener extends EventListener {
        // Public Instance Methods
                public abstract void actionPerformed(ActionEvent e);
    }

### Implemented By:

`AWTEventMulticaster`

### Passed To:

`AWTEventMulticaster.add(), AWTEventMulticaster.remove(), Button.addActionListener(), Button.removeActionListener(), List.addActionListener(), List.removeActionListener(), MenuItem.addActionListener(), MenuItem.removeActionListener(), TextField.addActionListener(), TextField.removeActionListener()`

### Returned By:

`AWTEventMulticaster.add(), AWTEventMulticaster.remove()`
