There are many kinds of animals. All animals make a sound and hear sounds made by other animals. Social animals are animals that have a name and two friends. They can talk to each other and spread rumors to others through friends. Dogs and cats are social animals, while tigers are not. You will create an inheritance hierarchy consisting of an interface and several animal classes. You must define an interface and an abstract class and leverage polymorphism. You will need to write the following methods in your program, though each class may not contain all of them. public String getName() public int getWeight() ⚫ public String makeSound() • Dogs make a "woof" sound. 。 Cats make a "meow" sound. Tigers make a "grrrrr" sound. ⚫ public void talk To(SocialAnimal animal) 。 When a dog talks to the specified animal, the dog barks and waves its tail. 。 When a cat talks to the specified animal, the cat purrs and smiles. ⚫ public void spreadRumor() 。 A social animal propagates a rumor on a social network through her friends. I.e., it talks to her friends who in turn talk to their friends and so on. More detailed instructions are provided in the Activities section. ⚫ public void hear(Animal[] animals) 。 When this animal hears from a group (animal_0, ....animal_n-2, animal_n-1} of the specified animals, animal_1 hears from animal_0, animal_2 hears from animal_1, and so on until this animal finally hears from animal_n-1. ⚫ public String toString() о Refer to the example in the next section. Examples The following method is provided in the AnimalMain.java file in your repository. public static void test1_2() { Animal tiger1 = new Tiger(300); Animal tiger2 = new Tiger(300); SocialAnimal happy = new Dog("Happy"); SocialAnimal lucky = new Dog ("Lucky"); SocialAnimal milky = new Cat ("Milky"); Animal[] animals = {tiger1, happy, lucky, tiger2, milky}; System.out.println("1. Testing makeSound and toString for(int i=0; i<animals.length; i++) { } System.out.println(animals [i].makeSound()); System.out.println(animals [i]); SocialAnimal yoda = new Cat ("Yoda"); .. "); System.out.println("\n2. Testing Yoda hearing animal sounds ..."); yoda.hear(animals); } The expected output of the method is as follows: 1. Testing makeSound and toString grrrrr 300 lb tiger [grrrrr] woof Happy [woof] woof Lucky [woof] grrrrr 300 lb tiger [grrrrr] meow Milky [meow] 2. Testing Yoda hearing animal sounds ... Happy hears grrrrr Lucky hears woof A tiger hears woof Milky hears grrrrr Yoda hears meow Activities 1. All files you write for the assignment should be in the "animal" package that has been provided in your repository. 2. Before writing code, complete the following UML diagram. You should commit your completed diagram to your repository (screenshot or PDF). <<abstract>> SocialAnimal name: String friend1: SocialAnimal firend2: SocialAnimal <<interface>> Animal + makeSound(): String + hear (Animal[] animals): void + <<create>> SocialAnimal(name: String) + setFriend1(friend1: Social Animal): void + setFriend2(friend2: SocialAnimal): void Cat Dog weight: int Tiger 3. Implement the classes in your UML diagram. If you have to change the classes so that they are different from the diagram, update the diagram too. 4. Complete the test3 method in AnimalMain.java. Use the provided social animals to create a social network depicted in the following diagram: Cat 2 Dog 4 Dog 5 Dog 2 Dog 1 Dog1 has Dog2 and Cat1 as friend1 and friend2, respectively. null Cat 3 Cat 1 Dog 3 null null Cat 4 Cat 5 null null null null null null null null A social animal has at most two friends. In the diagram above, A →B means that A has B as a friend. If dog1 starts gossiping, it talks to her friends, and friends of her friends talk to their friends, and so on. A rumor spreads through the population in the following order: dog1 → dog2, dog1 → cat1, dog2 → cat2, cat2 → dog4, cat2 → dog5, cat1 → cat3, cat1 → dog3, dog3 → cat4, dog3 → cat5. When test3 runs, your output should be 3. Testing dog1 spreading a rumor... Dog1 barks woof to Dog2 waving its tail. Dog1 barks woof to Cat1 waving its tail. Dog2 barks woof to Cat2 waving its tail. Cat2 purrs meow to Dog4 with a big smile. Cat2 purrs meow to Dog5 with a big smile. Cat1 purrs meow to Cat3 with a big smile. Cat1 purrs meow to Dog3 with a big smile. Dog3 barks woof to Cat4 waving its tail. Dog3 barks woof to Cat5 waving its tail. If * you are creating any other social network (for debugging), you may assume that it has a tree structure consisting of unique social animals like the example above.
