how to create dog door using java programming.

When the dog door opens it says "The door is opened" and when it closes it says "The door is closed"

It opens when it hears "Raw Raw" which is the specific sound for the owner's dog.

The programme also needs a remote class which can control the opening and closing of the door.

Some of the classes that should be used are Remote, BarkRecognizer, DogDoor and Bark.

Thank you
