Question

The interface Speaker is describe below. public interface Speaker{ public void speak(); public void announce(String str); } Create classes Dog and Philosopher implementing the Speaker interface. (The code for the general overview of the classes are provided you just need to fill the method and class headers and their code) and then create a driver class showing the abilities of interface, these tests are includes the ability of creating an object of Dog and Philosopher with interface reference, testing their polymorphic ability with invoking the methods of interface. and showing how we can use a method of child class of interface (Pontificate for the case of philosopher) using casting.

i will include the templates below which you will use to answer the question. you will just need to input the missing codes in the required spaces.
