Indirect array accesses

["Peter B. West" <pb...@powerup.com.au>]

This is another general Java question.  Again, if you Java gurus know a 
better forum for this stuff, please let me know.

I have found a solution to the problem of dynamic accessing of elements 
of class arrays in classes whose name is known at runtime.  Basically, 
type[] a =
(type[])(Class.forName(classname).getField(arrayname).get(null))

(I haven't tried it that form, mind you.)  Although it is not spelled 
out in the documentation, Field.get(), where the field is an array, 
returns an array reference, and Bob's your uncle.

Out of the solution comes another question.  I have a static initializer 
which can throw a ClassNotFoundException.  How do I handle this?  I 
can't attach a "throws" clause to the "static" keyword.  Do I just catch 
it and throw a RuntimeException?

I have found that throwing a RuntimeException in the static initializer 
will, when triggered, eventually generate an ExceptionInInitializerError 
at runtime.
