What to do with the files in this directory:

1. Compile TestFriendly.java and note how Friendly.java
is also compiled automatically. These two files are in
the "default package" associated with the current directory.

2. Try to compile TestGreetings.java and note that it won't 
compile because it can't find the classes it needs.

3. Next try this command:
> javac -classpath misc\greetings TestGreetings.java
This works beacuse you have told the compiler where the
classes needed to compile TestGreetings.java are located.

4. To run this program give this command:
> java -classpath .;misc\greetings TestGreetings
In this case you have specified the local directory as well
(indicated by the . and separated from the other directory
by the ;), so that the JVM can find *all* the classes it
needs, including the main class, TestGreetings.

4. Now edit TestGreetings.java and uncomment the import statement.
Also edit each of the files in the misc\greeting subdirectory
and uncomment the package statement in each. Then give this
command in the packages subdirectory:
> javac TestGreetings.java
> java TestGreetings
The program should now compile and run fine.
