How can I draw a curved line segment using QuadCurve2D.Double?

Question

Here is the line of code where I declare the curve:

QuadCurve2D.Double curve = new QuadCurve2D.Double(50,100,100,170,150,100);

Now what code can I use to draw this curve? I tried something like:

g.draw(curve);

but obviously that didn't work. Any suggestions?

I've made a minimum test case of what I think your describing here. This program works but I can't really help you unless I can see the code you are working with.

import java.awt.geom.*;
import java.awt.*;
import javax.swing.*;

public class CurveDraw extends JFrame {
        public static void main(String[] args) {
                CurveDraw frame = new CurveDraw();
                frame.setVisible(true);
        }
        public CurveDraw() {
                setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                setSize(400,400);
        }
        public void paint(Graphics g) {
                QuadCurve2D.Double curve = new QuadCurve2D.Double(50,100,100,170,150,100);
                ((Graphics2D)g).draw(curve);
        }
}
