In your listing the first file.

| The second file is the class file for our inner class. Yes, as we
| feared, inner classes are really just compiler magic. The compiler has
| created the inner class for us as a normal, top level class and named it
| by combining the class names with a dollar sign. The dollar sign is a
| valid character in class names, but is intended for use only by
| automated tools in this way. (Please don't start naming your classes
| with dollar signs). Had our class been more deeply nested, the
| intervening inner class names would have been attached in the same way
| to generate a unique top level name.

| Inner classes may also be declared withing the body of a
| method. Returning to the Animal class, we could put Brain inside the
| performBehavior() method if we decided that the class was only useful
| inside of that method.

|     Class Animal {
|         void performBehavior() { 
|             Class Brain { 
|                 ...
|             }
|         }
|     }

And in 6.0rc2 this method was not available.
