public class YuanHuan extends Applet

public void paint(Graphics g)

double w=getSize().width/2;
double h=getSize().height/2;
g.getColor(Color.green);
for(double th=0;th<10;th+=0.00003)

double r=Math.cos(16*th)+th;
double x=r*Math.cos(th)+w;
double y=r*Math.sin(th)+h;
g.drawOval((int)x-1,(int)y-1,3,3);


public static void main(String args[ ])

Frame f=new Frame("Draw");
YuanHuan p=new YuanHuan();
