Question

Java assignment.

• There are five classes. You figure out the inheritance hierarchy.
  • Animal, Dog, Brindle, Cat, Driver
  • Note: Brindle is a kind of dog that has stripes
• The following classes will have a makeSound method that displays the kind of sound the animal makes.
  • Animal, Dog, Cat
• In the Brindle class, you will have an instance variable
  • noOfStripes
• One of the classes should have an instance variable to hold the name of the animal
  • Name
• One of the classes should have an instance variable to hold the gender of the animal
  • Gender
• The dog class should have an instance variable
  • LevelOfMeanness (could be between 1 and 10)
• The cat class should have an instance variable
  • LevelOfCuteness (could be between 1 and 10)
• In your Driver class,
  • In the main method, create a local array that is able to hold 4 animals. The array elements should point to an Animal, Dog, Brindle and a Cat object (total of 4 objects).
• • For the Animal object, pass in the name and gender into the constructor.
  • For the Cat Object, pass in the name, gender and the level of cuteness into the constructor.
  • For the Dog Object, pass in the name, gender and the level of meanness into the constructor.
  • For the Brindle object, pass in the name, gender level of meanness and the noOfStripes into the constructor.
• • In another method, in the Driver class, do the following:
    • Using a for loop, go through the array and display the following
    • The name and gender of the animal
    • The sound the animal makes
    • The level of meanness if the animal is a Dog. Keep in mind, we want the sound as well
    • The number of stripes if the animal is a Brindle. Keep in mind, we want the sound and the level of meanness as well
    • The level of cuteness if the animal is a Cat. Keep in mind that we want the sound as well.
