The main method is static. Your p object is not: it is an instance field of the P class. Try this:

public static void main(String[] args) throw InterruptedException {
    EventQueue.invokeLater( new Runnable() {
        public void run() {
            P p = new P();
            p.repaint();
        }
    } );
}

You should always access Swing components from the event dispatch thread, which is why I put it all in a EventQueue invokeLater.
