One other thing..

How do I make classes communicate with each other. If I have a class Chore.java and it contains nothing in it except the main method, in that method I want it to execute a applet contained in Applet.java, how do I tell java to execute that, like this?

public static void main (String[]args) {
new Applet();
}


?????

How do I get classes to use each other and communicate?
I am used to writing small one class programs, and I want to expand.

First, make sure you import Applet

in the main method of Chore.java do something like this:
Applet obj = new Applet();


then call the method like this:
obj.whateverMethod();
