Running the application is very straight forward. You can use the following steps to run the app.
-
Install required dependencies using bundle
bundle install -
Run the application on the terminal
ruby config/environment.rb
- Require pry just allows us to get into the pry environment and test our code
require 'pry'
- This will be our superclass that all our other classes will inherit from.
- It initializes name and age and they are all accessible through the accessor macro
class Animals
attr_accessor :name, :age
def initialize(name, age)
@name = name
@age = age
end
end
- The child class cat inherting from Animal.
- A less than sign is used to show that Animal is the super class being inherited from.
class Cat < Animal
def speak
'meawww'
end
end
- The second child Dog of the class Animals and many other children can be created solong as a relation is shown.
class Dog < Animal
def speak
'woof'
end
end
- Calling our methods to check if our code runs well
- Close with binding.pry
cat = Cat.new('rose', 10)
cat = Dog.new('bubles', 5)
binding.pru
- Run your ruby file.
