I just used bash as an example. In real life one would prefer Ant. Any
scripting language or command language will do, and Java IDEs like Eclipse and
Netbeans provide their own build mechanisms (Netbeans's being based on Ant).

The idea was to provide a template for the underlying process that could be
re-expressed as needed in different environments.

The key concepts here are
- what a class is
- the relationship between class declarations and the name of the source file
- the relationship between class packages and the directory hierarchy
- the relationship between CLASSPATH and directory hierarchies
- what constitutes legal source code for a complete class definition
- the relationship between a class, its source file location and its class
file location.
- what the steps are to make a Java application build and run.
