Create the following abstract classes and regular classes from the UML diagram.

In this exercise Animal is an abstract class, which contains;

Two protected instance variables name(String) and legs(int). The protected variables can be accessed by its subclasses and classes in the same package. They are denoted with a '#' sign in the class diagram.

Getter and setter for all the instance variables, and toString().

Two abstract methods getSound() and isScary() (shown in italics in the class diagram).

Default values or animal are as follows; Name is Animal, and Legs is 0.

Details for Canis;

Default species is Canis

Canis is not scary when overriding the isScary method.

Details for Snake

Default color is Green.

Snake is scary when overriding the isScary method.

Details for Dog

Default species for dog is familiaris.

Default legs for dog is 4

Dog is not scary when overriding the isScary method

Write a test class to test these statements involving polymorphism and explain the outputs. Some statements may trigger compilation errors.

Explain the errors, if any [5 Points].

Animal s1 = new Snake("Snek", "Red", "Noodle"); // Upcast Snake to Animal

System.out.println(s1); // which version?

System.out.println(s1.getSound()); // which version?

System.out.println(s1.isScary()); // which version?

System.out.println(s1.getName());

System.out.println(s1.getLegs());

System.out.println(s1.getColor());

Snake c1 = (Snake)s1; // Downcast back to Snake

System.out.println(c1);

System.out.println(c1.getSound());

System.out.println(c1.isScary());

System.out.println(c1.getName());

System.out.println(c1.getLegs());

System.out.println(c1.getColor());

Animal s2 = new Animal();

Animal s3 = new Canis("Wolf", 4, "Lupus"); // Upcast

System.out.println(s3);

System.out.println(s3.getSound());

System.out.println(s3.isScary());

System.out.println(s3.getName());

System.out.println(s3.getSpecies());

Canis r1 = (Canis)s3; // downcast

System.out.println(r1);

System.out.println(r1.getSound());

System.out.println(r1.getName());

System.out.println(r1.getSpecies());

Animal s4 = new Dog("Goodboye"); // Upcast

System.out.println(s4);

System.out.println(s4.getSound());
