add an actionListener

hi,

im new to java , and im trying to get this to work , this is my code :

Java Code:

public class TextDemo extends JPanel implements ActionListener {
        protected static JTextField commandField;
        protected static JTextArea consoleArea;
        protected static JTextArea outputArea;
        private final static String newline = "\n";
        

        public void actionPerformed(ActionEvent evt) {
                String text = commandField.getText();
                consoleArea.append(text + newline);
                commandField.selectAll();

                // Make sure the new text is visible, even if there
                // was a selection in the text area.
                consoleArea.setCaretPosition(consoleArea.getDocument().getLength());
        }
        private static void createAndShowGUI() {
                JFrame frame = new JFrame("Client");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                
                Container contentPane = frame.getContentPane();
                contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.X_AXIS));

                JPanel left = new JPanel();
                left.setLayout(new BoxLayout(left, BoxLayout.Y_AXIS));
                consoleArea = new JTextArea(19,20);
                JScrollPane scrollPaneConsole = new JScrollPane(consoleArea);
                left.add(scrollPaneConsole);
                commandField = new JTextField();
                left.add(commandField);
                left.setBorder(BorderFactory.createTitledBorder("Console"));
                JPanel right = new JPanel();
                right.setLayout(new BoxLayout(right, BoxLayout.Y_AXIS));
                outputArea = new JTextArea(20,20); 
                JScrollPane scrollPaneOutput = new JScrollPane(outputArea);
                right.add(scrollPaneOutput);
                right.setBorder(BorderFactory.createTitledBorder("Output"));

                
                contentPane.add(left);
                contentPane.add(right);
                frame.pack();
                frame.setVisible(true);
        }

        public static void main(String args[]) {

                javax.swing.SwingUtilities.invokeLater(new Runnable() {
                        public void run() {
                                createAndShowGUI();
                        }
                });
        }

}

i want to be able to enter a text in the commandField and when pressing enter the text to be shown in the console area ,

why isnt my actionPerformed never gets called ??
