Converting application to applet

use the java.util.Formatter (http://java.sun.com/javase/6/docs/api/java/util/Formatter.html) to format your string then display it as you like : directly as a label in your applet or via a JOptionPane.

you can also use String.format()

http://java.sun.com/javase/6/docs/api/java/lang/String.html#format(java.lang.String,%20java.lang.Object...)

Here is what i have so far but I can't figure out why I get the error:

SimpleApplet.java:26: cannot find symbol

symbol : variable randomInt

location: class SimpleApplet

g.drawInteger(randomInt,15, 25);
