I want to use GeneralPath class to construct a shape of a regular octagon. Please help.

Why don't you use the much simpler Path2D class; you can add your eight points to it and be done with it.

kind regards,

I was using this code but it is not working. Can you tell me what is wrong with it?

public void paintComponent(Graphics g){
        float x,y;
		super.paintComponent(g);
		Graphics2D g2 = (Graphics2D)g;
		GeneralPath path = new GeneralPath();
        path.moveTo(200,200);
        for (int i = 1; i < 8; i++){
            double a = i*0.25*Math.PI;
            path.lineTo((float)Math.cos(a), (float)Math.sin(a));
            x = (float)Math.cos(a);
            y = (float)Math.sin(a);
            g2.draw(path);
            //printf("x %d,y %d: %f, %f\n", i,i,x,y);
        }
        path.closePath();
		g2.draw(path);
