For 169.1 saas homework #1 question #4, I have not yet read in the book about this which is what I plan to do later today.
So that may help me here.  For this question, it passes 4 of the 6 autograder tests.

Karen West, Homework #1, part 4, SaaS1, April 8th, 2013
 HW 1-4: Basic Object Oriented Programming

Part A: Create a class Dessert with getters and setters for name and calories. Define instance methods healthy?, which returns true if a dessert has less than 200 calories, and delicious? which returns true for all desserts.

Here is the framework:

class Dessert
    def initialize(name, calories)
        # Your code here
    end

    def healthy?
        # Your code here
    end

    def delicious?
        # Your code here
    end
end

Note: You may define additional helper methods.

Part B: Create a class JellyBean that extends Dessert, and add a getter and setter for flavor. Modify delicious? to return false if the flavor is "black licorice" (but delicious? should still return true for all other flavors and for all non-JellyBean desserts).

The JellyBean class should look like this:

class JellyBean < Dessert
    def initialize(name, calories, flavor)
        # Your code here
    end

    def delicious?
        # Your code here
    end
end

Note: As before, you may define additional helper methods.

=end

class Dessert
  def initialize(name, calories)
    # YOUR CODE HERE
    @name = name
    @calories = calories
  end

  def healthy?
    # YOUR CODE HERE
    if @calories < 200
      return true
    else
      return false
    end
  end

  def delicious?
    # YOUR CODE HERE
    #if class is Dessert, return true?
    #if (self =~ Dessert)
      #return true
    #else
      #return false
    #end
    return true
  end
end

class JellyBean < Dessert
  def initialize(name, calories, flavor)
    # YOUR CODE HERE
    @name = name
    @calories = calories
    @flavor = flavor
  end

  def delicious?
    # YOUR CODE HERE
    #if (@flavor != "black licorice") and (self =~ JellyBean)
    if (@flavor != "black licorice")
      return true
    else
      return false
    end
  end
end
