How to ignore a whole line of text that starts with // using a scanner class and delimiters : I am trying to read data from a .txt file, i need to be ignoring any line that starts with a // or a blank line but i can't seem to get the delimiter to work correctly.

    public void readVehicleData()
    throws FileNotFoundException
    {
        FileDialog fileBox = new FileDialog(myFrame, "Open", FileDialog.LOAD);
        fileBox.setVisible(true);

        String filename = fileBox.getFile();
        File vehicleData = new File(filename);
        
        Scanner scanner = new Scanner(vehicleData).useDelimiter("\"(,\")?");
        
        
        while( scanner.hasNext() )
        {
            String lineOfText = scanner.nextLine();

            System.out.println(lineOfText);

        }
        scanner.close();
    }




// this is a comment, any lines that start with //
// (and blank lines) should be ignored
