Question

For this assignment you will create a set of simple classes that model a cookbook. The cookbook will consist of set or recipes. Each recipe will consist of a set of ingredients and instructions. Your submission will consist of the below three classes and a test driver (the only class with a main()) that exercises the functionality of your system.

You will need to implement the following classes based on the description of their attributes and operations:

• Ingredient
  • name - the name of the ingredient
  • quantity - the amount of the ingredient
  • units - the unit of the quantity (e.g, tablespoon, or T, or Tbl)
  • require the creator to supply the name of the ingredient in order to create one
  • enable the user to retrieve and update each of the attributes appropriately
    
• Recipe
  • name - the name of the recipe
  • category - the category of the recipe
  • ingredients - a list of ingredients (you may assume no more than 20)
  • instructions - this would be a paragraph of text, no need to worry about steps
  • require the creator to supply the name of the recipe in order to create one
  • enable the user to retrieve and update each of the attributes appropriately
    
• Cookbook
  • name - the name of the cookbook
  • recipes - a list of recipes (you may assume no more than 20)
  • require the creator to supply the name of the cookbook in order to create one
  • enable the user to find recipes by name, returning only those recipes
  • Extra Credit (+1/3 letter grade): enable the user to find recipes by ingredient and return only those recipes

Answer 1

Done. Please go through the code and if there is any thing you want differently let me know. WIll look into it. Screenshot of the output is included as well
