InstructionsNow that you have some experience building basic, single-class applications, here is an opportunity to delve into making a full-fledged application with more than one class. You will start to implement a first version of a more complex class and create a test class to put it through its paces.Go to the Start Here page and download the Stepping Stone code .zip for the starter code for this assignment.To complete this assignment, review the following documents:Stepping Stone Lab Five GuidelinesStepping Stone Labs Two Through Six Rubric

/**
* Final Project
*
* For your Final Project:
*
* 1. Modify this code to develop a Recipe class:
*
a. change the void main method createNewRecipe() that returns a Recipe
*
* 2. FOR FINAL SUBMISSION ONLY:Change the ArrayList type to an
*
Ingredient object. When a user adds an ingredient to the recipe,
*
instead of adding just the ingredient name, you will be adding the
*
actual ingredient including name, amount, measurement type,
calories.
*
For the Milestone Two submission, the recipeIngredients ArrayList can
*
remain as a String type.
*
* 3. Adapt the printRecipe() method to print the amount and measurement
*
type as well as the ingredient name.
*
* 4. Create a custom method in the Recipe class.
* Choose one of the following options:
*
*
a. print out a recipe with amounts adjusted for a different
*
number of servings
*
*
b. create an additional list or ArrayList that allow users to
*
insert step-by-step recipe instructions
*
*
c. conversion of ingredient amounts from
*
English to metric (or vice versa)
*
*
d. calculate select nutritional information
*
*
e. calculate recipe cost
*
* f. propose a suitable alternative to your instructor
