v tnx 4 yr feedings
I'll reply in a while:
the problem statement was how to get a string representation of a fully qualified
class name stored in a class (that is, static) variable without having to type it.

You're using a constructor, so you're typing the class name: if this were allowed by
the problem statement, it would be useless, because I would simply accomplish the work
writing:
private static String className = "mypackage.MyClass";
instead of
private static String className = new MyClass().getClass().getName();
In addition it's not always possible or convenient instantiating MyClass: it would be
a very heavy object, it would perform some obscure operation, it should not be
instantiated for several reasons, or it cannot be i.e. when it's an abstract class...
The same holds true for Suresh Babu Koya who wrote:

Anyway using exceptions it's not as bad as might seem: they are very light objects.
Usages similar to this can be found frequently in the literature (see Daconta: Java
Pitfalls, first ed.)
tnx again, Sergio
