实现方法进入进度条

Question

这里我有一个Button的动作监听器和一个迭代进度条的方法Bar，如何将该方法实现到进度条中？

我曾尝试过pb.setString（iterator）;但显然，它不起作用，因为SetString只接受字符串。

{ 
     "latitude": ...
     "longitude": ...
}

我会创建一个SwingWorker。

SwingWorker<Void, Void> worker = new SwingWorker<Void, Void>() {
    protected Void doInBackground() {
          //do stuff
          setProgress(progressValue); //when you want to update the progress, do this
    }

}
worker.addPropertyChangeListener(new PropertyChangeListener() { //this runs whenever the progress is changed, to actually set the progress of the JProgressBar
            @Override
            public void propertyChange(PropertyChangeEvent evt) {
                if ("progress" == evt.getPropertyName()) {
                    int progress = (Integer) evt.getNewValue();


                    pb.setValue(progress);

                }
            }

        });
worker.execute();
