Stepping Stone Lab Five Guidelines Recipe Class With Accessors and Mutators

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. 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 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.

F. Propose a suitable alternative to your instructor.

Development Tips

· To add accessors/mutators, choose Refactor → Encapsulate Fields.

· You can also insert constructors by going to Source → Insert Code.

· Finally, you can also prompt the user for the recipe information instead of hard-coding it.

Stepping Stone Labs Two Through Six Guidelines and Rubric

Overview

· Beginning with Stepping Stone Two in Module Three, you will complete a series of related stepping stone labs that will help you build object-oriented programming skills that relate to your final project. Be sure to incorporate feedback from your instructor as you develop your work through the stepping stone labs and develop your final project.

· Note that Stepping Stone Lab One: Pseudocode is graded with a separate rubric.

Stepping Stone Labs Two through Six specifics:

Stepping Stone	Module	Title/Topic	Task Specifics
Two	Three	Data Types	Produce basic data types for a recipe manager program.
Three	Four	Validating Input With Branches	Develop a branched structure for a recipe manager program.
Four	Five	Entering Ingredients With Loops	Develop iterative loops for a recipe manager program.
Five	Six	Collection and Item Class With Accessors and Mutators	Develop the first version of the Recipe class and create a test class.
Six	Eight	The RecipeBox Driver Application	Produce a driver application for a recipe manager program.

Each of your programming assignments includes two parts:

· Code file(s)

· Written reflection as text file or Word document

· The assignment parts are submitted together with the written submission and with the code as a file attachment.

Critical Elements

The following  critical elements should be addressed in your project submission:

I. Code Reflection A brief explanation of the code, its purpose, and a brief discussion of your experience in developing it, including any issues that you encountered while completing the stepping stone and what approaches you took to solve them

II. Specifications Source code must meet its specifications as defined by the data and problem. However, this may require multiple attempts or iterations. You will be given credit for code that is well on its way to meeting specifications or solving the problem.

III. Correctness Source code must behave as desired. While correct code produces the correct output as defined by the data and problem, for the stepping stones you will receive credit for producing fully functioning code (producing no errors) that aligns with as many of the specifications as possible. Note: You should write your code in such a way that the submitted files execute, even if they do not produce the correct output.

IV. Readability Code needs to be readable to a knowledgeable programmer. In this course, readable code requires the following:

a. Consistent, appropriate white space (blank lines, spaces) and indentation to separate, distinct parts of the code and operations

b. Explicit, consistent variable names that clearly indicate the data they hold and are formatted consistently

c. Organized structure—clear design separating components with different responsibilities

V. Annotation All code should also be well-commented. This is a practiced “art” that requires striking a balance between commenting everything, which adds a great deal of unneeded noise to the code, and commenting nothing. Well-annotated code requires you to do the following:

a. Explain the purpose of lines or sections of your code, detailing the approach and method you took to achieve a specific task in the code.

b. Document any section of code that is producing errors or incorrect results.

c. Your assignment should be submitted as a zip file of the exported code and reflection text, as required.

d. Note that, although the stepping stone labs are graded, their main purpose is to provide useful practice and feedback that you can incorporate as you build the knowledge and skills you need to succeed in the final project.
