重用SwingWorker

Question

如何在不创建新子类SwingWorker的情况下重用子类SwingWorker，并更改DoInBackround（）以打开不同的JFrame / JDialog？

class Loading extends SwingWorker<Void, Void> {

    @Override
    @SuppressWarnings("Convert2Lambda")
    public Void doInBackground() throws InterruptedException {

        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                d.setVisible(true);
                new Taxi_Summary().setVisible(true);
               //here i want to open a new JFrames/JDialogs when a button is pressed

            }
        });

        Thread.sleep(2000);//2000 millis = 2 seconds

        return null;
    }

    @Override
    public void done() {
        d.dispose();

    }
}
