+/**
+ * Answer to Question.
+ *
+ * Answer to Question 1:
+ *
+ * - Q: Should the getLegs methods be abstract? Why or why not?
+ *
+ * - A: Yes. Because different animal have different number of legs. In animal
+ * class we didn't define how many legs an animal has.
+ *
+ * - Q: Should the canFly methods be abstract? Why or why not?
+ *
+ * - A: Yes. Because different animal have different ability to fly. In animal
+ * class we didn't define how an animal can fly.
+ *
+ * - Q: Should the Animal class be abstract? Why or why not?
+ *
+ * - A: Yes. Because different animal have different properties. In animal class
+ * we didn't define how an animal is.
+ *
+ * - Q: What kinds of test can you write inside the testAnimal method?
+ *
+ * - A: You can write test for the getLegs and canFly methods. Before that, you
+ * need to inherit the Animal class and override the getLegs and canFly methods.
+ * Because the Animal class is abstract, you can't create an object of it.
+ *
+ * - Q: Can you test object from the Animal, Dog, and Bird classes through the
+ * Flyer interface? Why or Why not?
+ *
+ * - A: No. Because the they didn't implement the Flyer interface. For Animal
+ * class, you can't because the canFly() method is abstract. For Dog class, you
+ * can't because it didn't declare it has implement the Flyer interface. For
+ * Bird class, you can't because the canFly() method is abstract.
