Drawing Circles

The previous applets in this chapter have only printed text. Here is an applet that draws a circle.

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

// assume that the drawing area is 150 by 150
public class JustOneCircle extends JApplet
  final int radius = 25;

  public void paint ( Graphics gr )
    setBackground( Color.lightGray );
    gr.drawOval( (150/2 - radius), (150/2 - radius), radius*2, radius*2 );

Here is what the applet paints with your Web browser:

Not all browsers can run applets. If you see this, yours can not.


What is the name of the method that drew the circle?
