This is not exactly true.  You can instantiate it in one code location 
only (because you do not have a name to refer to it) but you can of 
course have multiple instances and use it in multiple places (e.g. by 
having a creator method that returns the super class or interface that 
you use to define the anonymous class).

Not really, as Jeff already pointed out.  I'd concede that it is more 
cumbersome than in Ruby with blocks because of the limitations 
(variables used inside the anon class must be final for example).

Kind regards
