first, what you guys have done is dynamically refrencing a *loaded* class not
dynamically creating a class! if the class is not yet loaded it returns null.
and of course dynamically refrencing a class gives you nothing, I was wondering
if it is possible to load a class dynamically?
in Java there's a forName method on "Class" class that loads a class with given
string and that's what we use with applications with dozens of classes, because
it can take a long time for a big application to load all classes
automatically, frustrating the user. so we can give users of our program the
illusion of a faster start with the this trick: the class containing the main
method does not explicitly refer to other classes. first display a splash
screen. Then manually force the loading of other classes by calling
Class.forName
anybody? any suggestions for loading a class dynamically?

instantiation? I've always been under the impression( and hence, been

Thoughts? Discussion? Benefits? Would it be better to implement a factory
type pattern to create the new instances of classes?
