        btn2.addActionListener(new Btn1_actionAdapter(this));        contendPanel.add(btn1);
        contendPanel.add(btn2);
        this.getContentPane().add(contendPanel);
        this.setSize(400, 300);
        this.setVisible(true);
    }    public static void main(String[] args) {
        SimpleFrame simobj = new SimpleFrame();
    }    void button1_actionPerformed(ActionEvent e) {
        System.out.println("Button1 is clicked");
    }    void button2_actionPerformed(ActionEvent e) {
        System.out.println("Button2 is clicked");
    }    class Btn1_actionAdapter implements java.awt.event.ActionListener {
        SimpleFrame adaptee;        Btn1_actionAdapter(SimpleFrame adaptee) {
            this.adaptee = adaptee;
        }        public void actionPerformed(ActionEvent e) {
            adaptee.button1_actionPerformed(e);
        }
    }    class Btn2_actionAdapter implements java.awt.event.ActionListener {
        SimpleFrame adaptee;        Btn2_actionAdapter(SimpleFrame adaptee) {
            this.adaptee = adaptee;
        }        public void actionPerformed(ActionEvent e) {
            adaptee.button2_actionPerformed(e);
