I don't have a strong opinion on how the class should be declared, but I do 
think -- and very strongly -- that the Java entry-point convention is a massive 
kludge, highly non-representative of how any sane OO code would be written, and 
not at all an example to be followed.  As such, I think it would benefit your 
students if you made that very clear to them from the start (yes, there is a 
risk of confusion, but no student will be confused who wouldn't otherwise 
probably be mislead -- which is worse).

FWIW: the examples in the JLS3 all use an default access class to house the 
(specified to be required) public static void main(String args...) or public 
static void main(String[] args) entry-point.  The spec does not appear to care 
what access the class itself has (and there's no obvious reason -- technical or 
semantic -- why it should).  Does "private" work ?  If so then using that would 
be defensible.
