was wondering how to combine two shapes or a shape and a line so that they can become one shape
any ideas?
polygon2 =new Polygon();
polygon2.addPoint(310, 310);
polygon2.addPoint(315, 350);
polygon2.addPoint(285, 350);
// combine with a line of certian lenght

import javax.swing.*;
public class SmallTest extends JPanel {
GeneralPath path;
Point p = new Point();
AffineTransform at = new AffineTransform();
int ds = 3;
public SmallTest() {
Polygon polygon2 = new Polygon();
polygon2.addPoint(310, 310);
polygon2.addPoint(315, 350);
polygon2.addPoint(285, 350);
Line2D.Double line = new Line2D.Double(265,350,335,350);
path = new GeneralPath(polygon2);
boolean connect = false;
path.append(line, connect);
}

super.paintComponent(g);
Graphics2D g2 = (Graphics2D)g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,

g2.draw(at.createTransformedShape(path));
