Create a progress bar with the specified orientation, which can be either JProgressBar. Later, when the progress bar switches from indeterminate to determinate mode, invoking setString null makes the progress bar display its default string. The code snippet also sets the progress bar’s current value to 0. Here’s the statement that creates the progress monitor: A tutoril bar can be reused; a progress monitor cannot.

Now let’s rewrite ProgressBarDemo to use a progress monitor instead of a progress bar.
The long-running task is implemented by LongTask. The code snippet also sets the progress bar’s current value to 0. If you provide null for this argument, the note is omitted from the dialog.
