Question #12
Prepare an applet called FourCorners. Draw a circle in the top left corner; an oval in the bottom right; a rectangle in the top right and a line in the bottom left. Put you're name centered on the applet. The program is started below. Please remember to include You're code in reply and a screen shot.:
import.java.applet.*;
import.java.awt.*;
public class FourCorners extends Applet
{
public void paint(Graphics g)
{
g.fillOval(0,0,50,50);
I don't see what the problem is here. The problem is practically solved for you already.
The circle is already drawn (that's the oval with the same height and widht).
The oval can be drawn the same way, but by varying the height and width from each other.
The rectangle can be done with the fillRect method of g
The line can be drawn with the drawLine method of g.
Your name can be put in place with the drawString method of g.
so all you really need to do is determine WHERE to put the components, which is simple geometry.
if you need help with the parameters for those methods, you should consult the API for Graphics. I'm not going to supply you with those. You need to do SOME of this homework for yourself.

No, my religion forbids me to do that.

There, there now! Don't let those nasty people upset you. This code is exactly what you need.import javax.swing.*;
