Question

Write a class called Animal with an default sound() method that does not output a specific animal sound. Instead, the generic output should be the statement, An animal makes a sound based on the animal that it is. The default constructor for Animal should also print I am an animal to standard output.

Create child classes for the following animals:

  • pig
  • sheep
  • duck
  • cow

The default constructor should print out I am a xxx, where xxx is the name of the animal. Create a sound() method for each new child class, which overrides the default method from the Animal class. The child class sound() method will print a different sound (word descriptor) for each animal, based on the child class:

  • pig says “oink”
  • sheep says “baah”
  • duck says “quack”
  • cow says “moo”

This sound() method does not generate an actual sound; it only prints the word descriptor to standard output.

Write a main() that creates several instances of each animal, and then calls each animal instance’s sound() method, so that different animals print different sounds accordingly.

Create another class called AnimalTest that reads the command line user input and creates the appropriate Animal child class based on the type of animal, and then calls the animal’s sound() method. Take some time to reflect on which class to create.
