Implement the Speaker interface: public interface Speaker { public void speak(); public void announce(String str); } Then, create three classes that implement Speaker in various ways: ● SpeakerOfTheHouse: speak method prints "I am Speaker of the House.", and the announce method takes the name of a bill in the form of a string and prints it in the sentence "The [bill] has passed!" • SportsAnnouncer: speak method prints "Goal!", and the announce method takes the name of a team in the form of a string and prints the sentence "The [team] have scored a goal!" • Actor: speak method prints "I've been nominated for three Academy Awards.", and the announce method takes the name of a movie in the form of a string and prints the sentence, "I'm currently staring in [movie]." Create a driver class, and in the main method, prompt the user to enter three Strings the name of a bill, the name of a sports team, and the name of a movie. Then, create an object from each of the classes described above and call the speak and announce methods of each object, using the strings provided by the user.
