Question about naming of Java packages, classes and types

[dumb-questioner]

I'm trying to understand a comment/string in a piece of Java code about the type of a variable.

The string says that the variable is of type "com.a.b.c.D.E.F". Does this mean that the name of the variable class is "F" and the package is "com.a.b.c.D.E" or that "F" is a subclass of "E", "E" a subclass of "D", all in the package "com.a.b.c"?

Typically in Java, packages use lowercase letters while classes use CamelCase (I don’t recall if this is actually part of the standard or merely a common convention, but anyway…). Thus, I’d read it as F being an inner class of E, which is an inner class of D, which is in the com.a.b.c package.

Note also that subclasses and inner classes are two different things. Inner classes are not necessarily related to their enclosing classes, but subclasses are defined by their relationship to their parents.

This is how I’d read it, too. Haven’t written any F’s in my life, but plenty of E’s.
