2 questions ( semicolon after empty methods and paint()/paintComponent())

1. Is there any difference writing:

publicvoid mouseEntered(MouseEvent e){};

publicvoid mouseMoved(MouseEvent e){};

publicvoid mouseClicked(MouseEvent e){};

publicvoid mouseExited(MouseEvent e){};

than

publicvoid mouseEntered(MouseEvent e){}

publicvoid mouseMoved(MouseEvent e){}

publicvoid mouseClicked(MouseEvent e){}

publicvoid mouseExited(MouseEvent e){}

2.

I have a JPanel which I change the graphical look of very often in my application.

What's the difference if I override paint() or paintComponent() in my JPanel?
