New class with actionPerformed

Question

This is part of my code:
//setup buyerJButton
                    buyerJButton = new JButton ();
                    buyerJButton.setText("Buyer");
                    buyerJButton.setBackground( Color.YELLOW );
                    contentPane.add( buyerJButton );
                    buyerJButton.addActionListener(
                         new ActionListener(){
                              public void actionPerformed( ActionEvent event )
                                   f = new BidFrame() extends JFrame;
                                   f.setVisible(true);
                                   //JFrame frame = new JFrame("Bid");
                                   //frame.setVisible(true);
                    );I want to create a new class within the actionperformed bit, so a new window can appear once clicked on Jbutton... it doesn't seem to work
Can anyone help? what am i doing wrong? Its the two lines with f = and f.set thats giving me propblems

Answer 1

I would implement it like this:
private void whatever ()
    // Skipping code here...
    JButton buyerJButton = new JButton();
    buyerJButton.addActionListener(
        new ActionListener() {
            public void actionPerformed(ActionEvent event)
                BidFrame f = new BidFrame();
                f.setVisible(true);
    return;
// BidFrame defined as an inner class
private class BidFrame extends JFrame
    // Skipping code here...
}
