Get Mouse Position
MouseInfo.getPointerInfo().getLocation() might be helpful. It returns a Point object corresponding to current mouse position.
PointerInfo a = MouseInfo.getPointerInfo();
Point b = a.getLocation();
int x = (int) b.getX();
int y = (int) b.getY();
System.out.print(y + "jjjjjjjjj");
System.out.print(x);
Robot r = new Robot();
r.mouseMove(x, y - 50);
