Tony, can you please tell me what are top-level inner classes and top-level classes

[Tony Alicea]

Nested classes are classes defined inside other classes. This was new with Java 1.1. What book are you using to prepare? This subject is kind of 'heavy' and it's better to read something about it first. The SUN specification is in:
http://java.sun.com/products/jdk/1.1/docs/guide/innerclasses/spec/innerclasses.doc.html
Let us know...

are nested toplevel classes and static inner classes the same??

[Jim Yingst]

Yes. Different authors use the both terms, and Sun is not really consistent either. It's a mess.
