      You get an error there because you can't put objects into a signature.

      Basically, every time you call a method (and a constructor is a kind of method) you can pass any object you like as long as it fits the signature of that function. But when defining a signature it may only contain modifiers (public, final, static, etc.), a type (if it's no constructor), a name and a list of parameter types and names.
