Why use string-based binding like that in Java, among whose main strengths is 
rigorous type safety?

Sometimes in frameworks you'll do that, e.g., name an implementing class in a 
properties or XML configuration file, but the cost is always deferral of 
less-expensive compile-time safety to later, more costly run-time type 
failures. The benefit had better be worth it, and also worth the fragmentation 
of logic across more source artifacts.

I've seen the sacrifice made in code, too. That's just an execration. One 
egregious example I saw used reflection and casting to obtain a no-argument 
constructor based on matching class names to certain other class names, but 
still requiring casting through those same types. They sacrificed type safety, 
performance, simplicity and good sense to create a "factory" that had none of 
the benefits of an actual factory.

Prefer compile-time type assertions to run-time matchups.
