    You didn't add an ActionListener to the button:
    [code]
    class Frame;

    JButton helloWorld;

    public void init() {
    helloWorld = new JButton("Hello world");
    b.addListener(this);
    add(b);
    }

    public void actionPerformed(ActionEvent e) {
    if (e.getSource = helloWorld) {
    System.out.println("Hello world pressed");
    }
    [/code]
