Graphics? [resolved]

[Dillinger4]

Anybody know how i can do this?
Im just trying to simply make a
circle on a canvas. I can get it to work
as an applet but that's about it.
Thanks

   import javax.swing.*;
   import java.awt.*;
   import java.awt.event.*; 
  
   public class Shape {
     public static void main(String[] args){
       new Circle(); 
    }

    Canvas c; 
    JFrame jf;
  }
 
  class Circle extends Shape{
  
   public Circle() {
    c = new Canvas();
    jf = new JFrame("Circle!");
    jf.addWindowListener(new WindowAdapter(){
       public void windowClosing(WindowEvent e){
          System.exit(0);
       }
    });

     Dimension size = jf.getSize();
     Insets i = jf.getInsets(); 
     int height = size.height - i.top - i.bottom;
     int width = size.width - i.left - i.right;

    c.setSize(height,width);
    jf.getContentPane().add(c);
    jf.setSize(400,300);
    jf.setVisible(true);
  }
 
   public void paint(Graphics g){
    g.setColor(Color.red);
    g.drawOval(50,50,50,50); 
   }
  }
