Chapter 3 - Inheritance
Exercise 2: Cupcakes
We have a Confection
class representing baked desserts below. Your job is to create a new subclass of Confection
, named Cupcake
. Cupcakes need to be baked just like other confections, but they also need to be frosted afterward.
Write a prepare
method for your Cupcake
class that prints "Baking at 350 degrees for 25 minutes."
, and then prints "Applying frosting."
Do this without duplicating the puts
line from the prepare
method of the Confection
class.
Solution
class Confection
def prepare
puts "Baking at 350 degrees for 25 minutes."
end
end
class Cupcake < Confection
def prepare
super
puts "Applying frosting."
end
end
# The below code should output the following
# 2 lines of text:
#
# Baking at 350 degrees for 25 minutes.
# Applying frosting.
cupcake = Cupcake.new
cupcake.prepare
