            int x = (int) b.getX();
            int y = (int) b.getY();

            System.out.println(x);

        }
    public void mouseClicked(MouseEvent e) {
        System.out.println("mouseClicked");  
        }
}

dies alles ist mein code, also bitte einfach erklären, wie impliment, dass eine Maus checker Sache.
Danke!
