Milestone Two Guidelines And Rubricthe Recipe Classoverviewin Your Fin

The final project involves creating a program to manage a collection of recipes. The core of this project is developing a Recipe class that holds all recipe details, including methods for creating and printing recipes, as well as a custom method with pseudocode that will be added later. Your submission must include two Java files: Recipe.java and Recipe_Test.java.

The Recipe class should contain instance variables such as recipe name (String), servings (integer), ingredients (list or array of Strings), and total calories (numeric). It must have appropriate getters and setters, constructors, a method to print the recipe, and a method to create a new recipe based on user input. Additionally, you should include pseudocode for a selected custom method from the lab's list. The Recipe_Test class should contain a main() method that creates a Recipe object via constructor, prints it, and prompts the user to create a new recipe using the relevant method.

Your implementation should adhere to proper use of data types, employing numeric and string types correctly, and managing multiple values with arrays or lists. Control structures such as if-else statements, loops, and other flow-control mechanisms must be used appropriately to meet the scenario requirements. The class should utilize methods with parameters, return types, and invoke object services effectively. Inline comments should explain design decisions to facilitate maintenance.

The development of a Recipe class as part of a recipe management program encapsulates several fundamental principles of object-oriented programming (OOP). This class must model a recipe with attributes that include a name, number of servings, ingredients, and total calories. Properly designed, these attributes utilize a mixture of string, integer, and floating-point data types, aligning with the scenario's data management needs.

Managing multiple ingredients requires the inclusion of an array or list structure, providing a flexible, organized way to handle multiple data points within a single object. This approach allows efficient management of recipe components, facilitating operations such as adding, removing, or displaying ingredients. In Java, the ArrayList class from the Java Collections Framework is often preferred for its dynamic resizing capabilities, although simple arrays can also suffice depending on the scope.

Several control structures are pivotal in implementing the logic of the class. Conditions (if-else statements) are essential for validating input, such as ensuring ingredients are not empty or calorie counts are positive. Loops (for, while) are used to iterate over ingredient lists for display or modification purposes. These structures ensure the program's robustness and flexibility, making it responsive to various user inputs.

Methods in the Recipe class should include both getters and setters (accessors and mutators) for encapsulating data, along with constructors for object initialization. A parameterized constructor can initialize all attributes, ensuring a complete recipe object upon creation. The printRecipe() method displays the recipe details in a formatted manner, enhancing readability.

The createNewRecipe() method involves collecting user input (via the Scanner class or similar). This method should prompt the user for each attribute, validate input where necessary, and assign values to the object's attributes. Pseudocode should outline the logical steps for implementing a custom feature, such as adjusting ingredients or calculating nutrient information, providing a blueprint for future development.

The accompanying Recipe_Test class serves to demonstrate the class functionality. It creates a new Recipe using a constructor, displays the recipe, and invokes the creation method to accept fresh input. This separation of concerns emphasizes OOP principles: creating objects, invoking methods, and ensuring modular, maintainable code.

Successfully completing this project demonstrates proficiency with data types, control flow, method design, class construction, and documentation. Proper inline comments clarify the reasoning behind design choices, aiding future maintenance efforts. Overall, this structured approach to building the Recipe class lays a solid foundation for a more comprehensive recipe management system.
