Hi,

Please keep in mind that all I have studied so far is the first programming 
chapter of Java For Programmers, by Deitel. We don't get to anything but public 
classes until Chapter 8. Is this anywhere in the ballpark?

Here's an analogy that seems to work for me. If you've ever worked with sub 
programs in Cobol, a public class is  something like a Cobol subprogram. A 
Cobol subprogram is a program all by itself, with its own working storage and 
routines. You can execute it from another Cobol program. The main Cobol program 
can see all of the variables and routines in the subprogram. I'm pretty sure 
that like Java, Cobol forces you to have one program per file. In Java, you 
have to have one public class per file.

At this point, we haven't talked about any other methods besides main, so 
that's all we know about methods. We don't know about private or anything else 
right now.
