Overview: Now 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. This stepping stone lab is the point where we start to pull all the elements of the course together. You will start to implement a first version of the Recipe class and create a test class to put it through its paces. Be sure to review the Stepping Stone Lab Five guidelines before beginning this lab. The completed code (.java file) from Stepping Stone Lab Four is included in this module to use as a reference for comparison of your work in Module Five as well as moving forward. This code serves a number of functions: ? It allows you to review your own submitted code. ? You may utilize it as a useful foundation for Stepping Stone Lab Five as well as other assignments to come. ? Together with instructor feedback on your submitted code, you are building your own final project application. As you are developing the code in this stepping stone lab, you should consider how you can transition it to your final project. Eventually, the user input for collecting the ingredients into an ArrayList of strings will be converted to an ArrayList of Ingredient objects. Think about the variable names you are using and where in the code you are collecting the ingredient input.

SteppingStone5_Recipe -

recipeName: String

- servings: int

- recipeIngredients: ArrayList

- totalRecipeCalories: double

+ getRecipeName(): String

+ setRecipeName(String): void

+ getServings(): int

+ setServings(int): void

+ getRecipeIngredients(): ArrayList

+ setRecipeIngredients(ArrayList): void

+ getTotalRecipeCalories(): double

+ setTotalRecipeCalories(double): void

+ printRecipe(): void

+ addNewRecipe(): SteppingStone5_Recipe

Prompt: In this stepping stone lab assignment, you will build a Recipe class, getting user input to collect the recipe name and serving size, using the ingredient entry code from Stepping Stone Lab Four to add ingredients to the recipe, and calculating the calories per serving. Additionally, you will build your first custom method to print the recipe to the screen. Specifically, you will need to create the following: ? The instance variables for the class (recipeName, serving size, and recipeIngredients) ? The methods (the accessors/mutators, the constructors, and the extra print details method) for the class ? A custom method to print the recipe out to the console *To test the functionality of your finished code, use the SteppingStone5_RecipeTest.java file *Replace the public static void main(String[] args) with public SteppingStone5_Recipe createNewRecipe() Guidelines for Submission: This assignment should be submitted as a Java file. Extending This Lab for Your 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.
