Error that method expects double, but my variable is a double

Question

im making a screenshot program
            Robot robot = new Robot();
            area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
            BufferedImage bufferedImage = robot.createScreenCapture(area);
            Image image = toImage(bufferedImage);it says area needs to be a double, and area is a double. even when i delcare area right there by putting double in front of that line i get the same error.

Answer 1

ok i changed some stuff up a bit after seeing what you guys pointed out
now i am left with
            Robot robot = new Robot();
            Rectangle area = new Rectangle();
            BufferedImage bufferedImage = new BufferedImage(100, 100, BufferedImage.TYPE_INT_RGB);
            area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
            bufferedImage = robot.createScreenCapture(area);
            Image image = toImage(bufferedImage);but its telling me toImage isnt a method in java.awt.image.BufferedImage (and i checked the api and its not a method there).
So what would I use to make it an image? Here is the whole thing::
            Robot robot = new Robot();
            Rectangle area = new Rectangle();
            BufferedImage bufferedImage = new BufferedImage(100, 100, BufferedImage.TYPE_INT_RGB);
            area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
            bufferedImage = robot.createScreenCapture(area);
            Image image = toImage(bufferedImage);
            try
                FileOutputStream output = new FileOutputStream("screen.jpg");
                JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(output);
                encoder.encode(bufferedImage);
                output.flush();
                output.close();
                log.append((new java.util.Date()) + " Image Captured");
            }
