I want to show one JLabel and one JComboBox when one particular RadioButton is selected in previous frame, otherwise it should be hidden. Even when I implement ComponentListener in that class his abstract methods(componentShown(), componentHidden()) are never called.
Can I call componentShown() method from a class that extends JFrame instead of JPanel ? If yes, how?

I think that your problem can be handled pretty easily, without even getting into these event handlers. Just pass a variable from your initial frame, when the RadioButton is selected, to the new frame (maybe a boolean variable with true value). Then, in your new fame, simply show the components, based on the value of that variable.
I hope you can handle the passing of variables, by handling the constructor parameters of your new frame.
Hope this helps ! Any clarifications required, please comment.
