Circle divided in 4 equal part in JAVA Applet.

1 way Easy without loop
CODING:
 /*<applet code="cor" width=455 height=455>
<param name="radius" value="180">
</applet>*/
import java.applet.*;
import java.awt.*;
public class cor extends Applet {
       public void paint(Graphics g){
           int R=Integer.parseInt(getParameter("radius"));
           int d=R*2;
           g.drawOval(0,0,d,d);
           g.drawLine(R,0,R,d);
           g.drawLine(0,R,d,R);
         }
}
OUTPUT
