Question

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()

1. Modify this code to develop a Recipe class: A. Change the void main method createNewRecipe() that returns a Recipe 2. 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 add the actual ingredient including name, amount, measurement type, and 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 allows users to insert step-by-step recipe instructions. C. Convert ingredient amounts from English to metric (or vice versa). D. Calculate select nutritional information. E. Calculate recipe cost.

What will be the code? And can you explain step by step on how to enter it.

Answer 1

Done. I have used Recipe class only. Dont udnerstand the exact purpose of Loop class. You can ignore it. Please have a look and in case of doubt please leave a comment. I have not removed your comments so that it is easy for you to understand the code. After the code is clear to you , please remove your comments.
