I do not understand why one would want to teach "nested new 
expressions".  What is so special about invoking new for constructor 
arguments?  Basically you have a constructor invocation and pass on 
references.  One or more of those references just happen to point to 
objects just created on the spot themselves.

You can do this, but it seems to me as meaningless as to teach about 
nested new:

   final Long l = new Long(new Integer(123));
   final Long[] a = new Long[] { new Long(234) };
   final Long[] b = { new Long(345) };

Kind regards
