How do I test if one class is an 'instance of' another class when both of the operands are, in fact, classes? I can check whether an object is an instance of a class, but in this case I have two classes -- dynamic at run time -- and I want to see if one implements the other. Thanks!

Notice that assignableFrom has the *reverse logic* of instanceof! That is: (a instanceof B) <==> (B.class.assignableFrom(a.getClass())) [ May 20, 2002: Message edited by: Ilja Preuss ]
