No, it doesn't. Again, the Java Language Specification defines methods and
objects, and they are not the same thing. I have pointed you to it.

'setMethod' is a variable, not a method.

'invoke()' is a method.

How exactly do you imagine that this proves a method is a class instance?
All your code proves is that there exists a class instance that can describe
and invoke a particular method. There is nothing in your code that shows, let
alone proves "beyond any doubt", that a method is an instance of a class. It
couldn't, because a Java method is not an instance of a class.
