Hi list...
I have a superclass, let's say it's Dog. Then, I have some extensions of Dog,
like so:
Schnauzer extends Dog
Poodle extends Dog
In the Dog constructor, I want to prevent a Dog from being instanced directly,
but when I include this line in the superclass constructor:
throw new IllegalOperationError("Class must be instanced through one of Dog's
subclasses.");
...all the base class instances throw the error. How best to prevent the
superclass from being instanced on its own?
Thanks,
- Michael M.
