Which of the following statements about interfaces are correct? (T/F)

Interfaces actually stand for an interface (protocol) between a client (interface user) and a server (implementing class).

Interfaces are used to call static components of a class.

Using interface references you can reference all the public components of an object that have been defined in the corresponding interface-implementing class.

A client (caller) can use inteface reference to access all methods of the Interfaces and thus archive polymorphism behavior.

Using interfaces you can simulate multiples inheritance.
