So I'm making a Hangman game, and for the sake of completeness I want to have a HELP feature. When the Help button is clicked, a browser window should open up (not *within* the game frame... but just generally) and display the HTML Help file. How do I do this?

So I have a full GUI, with a HELP button (a JButton) with an added Action Listener defined as follows:
(this is actually an inner class within another GUI class)

HelpListener implements ActionListener{
public void actionPerformed(ActionEvent evt){
//...insert code here, that will open up a browser window displaying a HTML help file (containing Hangman Help information)
}
}


Any help would be much appreciated.
