How to replace run-time instanceof check with compile-time generics validation

Question

Got a little puzzle for a true Java Generics specialist... ;)

Let\'s say I have the following two interfaces:

interface Processor {
    void process(Foo          


        

Answer 1

No, that's not what Java Generics were designed to do.

Also, in my opinion, the need for the type check indicates a problem with the design. I'd suggest trying to re-design it so that this is not necessary.
