To answer your first question, restructure you code to create the frame and it's contents in your class's constructor like this

class abc implements ActionListener {
    public static void main(String args[]) {

        new abc();
    }

    abc() {
        JFrame frame = new JFrame("Test Frame");
        JPanel panel = new JPanel();
        Container contpane;
        contpane = frame.getContentPane();

        // added all Radio Buttons
        JRadiobutton jb = new JRadioButton("test1");
        JRadiobutton jb1 = new JRadioButton("test2");
        jb.addActionListener(this);
        jb.addActionListener(this);

    }

    public void actionPerformed(ActionEvent evt) {

    }
}

and I don't understand the other questions.
