By the end of this, students should be able to:
- Give an example of a class method you already use.
- Diagram the invocation pattern between
#initialize
and.new
. - Contrast defining class methods with defining instance methods.
- Contrast invoking class methods with invoking instance methods.
Sometimes a method is associated with a class, not an object.
Let's discuss the code below:
class FullCat
def self.mouse
puts "I'm in the cats stomach"
end
def escape_mouse
puts 'I escaped the cat'
end
end
- Make a class for an animal aside from a cat.
- Create at least two instance methods.
- Create at least two class methods.
- Bonus: Have an instance method call a class method.
