Step 5. ...For example, look in the Source Editor for the saveMenuItem.setMnemonic(); that

Step 6. In the Source Pane, the new event-handler method stub should look like
the following:

void exitEvent(ActionEvent e) {

}

Add the following line above this method.

// Menu event handlers


Step 12. Replace the blank line between the curly braces with the following line
of code.

masterNavBar.doClick(NavigationBar.BUTTON_COMMIT);

Step 17.  Enter the following inside the blank method stub:

JOptionPane.showMessageDialog(
   this,
   aboutMessage,
   aboutTitle,
   JOptionPane.INFORMATION_MESSAGE);


Step 18. Go to the end of the declaration section by locating the line JMenuItem
aboutMenuItem = new JMenuItem();. Add the following right after this line. This code declares variables for the dialog box and assigns values to those variables.

String 	  productName 	  	= 	"Departments Browser";
String 	  productVersion 	= 	"Version 1.0";
String 	  productCopyright  	= 	"Copyright (c) 2001";
String[]  aboutMessage 		= 	{productName, productVersion, productCopyright};
String 	  aboutTitle 		= 	"About " + productName;
