JMenu help for opening an HTML page on a local machine

Question

It’s hard for me to find a tutorial that allows JMenuItem to flag ("Help Content") to open an html page that displays help content. The html page will be stored on the local machine, for example C: \ help. I created the following action listener, which, when clicked on, displays a string. This is for test purposes only to show that my ActionListener is working.

   private void jMenuItem3ActionPerformed(java.awt.event.ActionEvent evt) {
            // TODO add your handling code here:
            JOptionPane.showMessageDialog(null, "Help File Popup");
        }

So, how would I replace:

JOptionPane.showMessageDialog(null, "Help File Popup");

Thus, when jMenuItem3 is clicked, the html page is loaded in the browser by default. Thank you very much in advance!

editorPane.setEditable(false);
java.net.URL helpURL = TextSamplerDemo.class.getResource(

if (helpURL != null) {
try {
    editorPane.setPage(helpURL);
} catch (IOException e) {
    System.err.println("Attempted to read a bad URL: " + helpURL);
}
} else {
System.err.println("Couldn't find file: TextSamplerDemoHelp.html");
}

//Put the editor pane in a scroll pane.
JScrollPane editorScrollPane = new JScrollPane(editorPane);
editorScrollPane.setVerticalScrollBarPolicy(
