Can i make this work with a number specified in the constructor?

Question

Hi everyone
I posted a couple of days ago and i have managed to advance a bit since then.
Here i have a class called "flower" and it draws a flower with two leaves and 12 petals using the classes "petal and "leaf".
However, ideally i would like to be able to make this work with a number of petals specified in the constructor, not just 12.
is this possible or do i need to rewrite the entire class?
import java.awt.*;
import java.awt.geom.*;
public class flower {
    private Shape circle;
    private Shape stem;
    public flower()   {
        circle = new Ellipse2D.Double(-25, -25, 50, 50);
        stem = new Line2D.Double(0.0, 0.0, 0.0, -200.0);
    public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D)g;
    g2.setPaint(Color.green);
    g2.setStroke(new BasicStroke(5)); // Line width 8 pixels
    g2.draw(stem);
    // Add the petals
    petal P = new petal(Color.red);
    // Scale, translate and rotate the petal into place.
    AffineTransform orig  = g2.getTransform();
    AffineTransform T = AffineTransform.getTranslateInstance(0.0, -25);
    for (int k = 0; k < 12; k++) {
      double angle = k*Math.PI/6.0;
      AffineTransform A =  AffineTransform.getScaleInstance(1.0, 1.0);
      A.preConcatenate(T);     // Scale, then rotate
      AffineTransform R = AffineTransform.getRotateInstance(angle);
      A.preConcatenate(R);     // Scale, translate and then rotate
      g2.transform(A);
      P.paint(g);
      g2.setTransform(orig);     // Restore original transform
      g2.setPaint(Color.yellow);
      g2.fill(circle);
      leaf L = new leaf();
      AffineTransform B = AffineTransform.getTranslateInstance(0.0, 0.0);
      B.translate(340, 425);
      B.scale(1.0, 1.0);
      B.rotate (Math.PI/6);
      g2.setTransform(B);     
      L.paint(g);
      g2.setTransform(orig);     // Restore original
      leaf L1 = new leaf();
      AffineTransform C = AffineTransform.getTranslateInstance(0.0, 0.0);
      C.translate(285, 430);
      C.scale(1.0, 1.0);
      C.rotate (Math.PI/-6);
      g2.setTransform(C);     
      L1.paint(g);
      g2.setTransform(orig);     // Restore original
}I am tempted to make "flower into a class that extends "petal" would this make it easier for me to achieve my goal?
Any help would be great
Thanks Carl

Your NewFlower class extends petal. You NewFlower constructor calls super( color, petnum ), so the petal constructor is invoked. In the petal constructor, you ignore petNum. You do nothing else in the NewFlower constructor, so petNum is ignored there as well.
What makes you think that in this orgy of ignoring petNum, that any petNum variable will magically get set, or that your flower will now magically have the right number of petals?
