Why can't I assign lambda to Object?

Question

I was trying to assign a lambda to Object type:

Object f = ()->{};

And it gives me error saying:

 The target type of thi         


        

Answer 1

It's not possible. As per the error message Object is not a functional interface, that is an interface with a single public method so you need to use a reference type that is, e.g.

Runnable r = () -> {};
