Answer 1

    public void paintComponent(Graphics g){
         super.paintComponents(g);

      int x[] = {1,2,3};
      int y[] = {4,5,6};
      int npoints = x.length;//or y.length

      g.drawPolygon(x, y, npoints);//draws polygon outline
      g.fillPolygon(x, y, npoints);//paints a polygon

}
