Your Ingredient class will model the details of individual ingredients in a recipe. Based on Stepping Stone Labs Two and Three, you will create an Ingredient class and give it the basic attributes: name, amount, unit of measure, and calories.

Additionally, you will add code to validate the data type of the user input. This Ingredient class will be modified for the submission of your final Recipe Manager application; however, it should be functional code that accepts user input for each variable. Specifically, the following critical elements of the final project must be addressed:

The development of an Ingredient class is central to creating an effective Recipe Manager application. This class is designed to encapsulate all necessary details pertaining to individual ingredients, promoting modularity and ease of maintenance in the overall program. Each attribute within this class—name, amount, unit of measure, and calories—serves a specific purpose and must be carefully defined and validated to ensure data integrity.

To begin, the 'name' attribute is a string representing the ingredient's name, such as "sugar" or "flour." Using a string here allows flexible storage of character-based data. The 'amount' attribute should utilize a numerical data type, such as 'double' or 'float,' to accommodate fractional quantities common in recipes—e.g., 1.5 cups of sugar. The 'unit of measure' attribute is another string, capturing units like "cups," "tablespoons," or "grams," which are essential for precise measurements.

The 'calories' attribute should employ an integer or double data type, representing the caloric content of the ingredient. The choice of data type depends on whether fractional calories might be relevant; typically, an integer suffices because calories are often rounded to whole numbers.

Implementing data validation is crucial to maintain program robustness. For instance, when accepting user input, the class should ensure that the 'amount' and 'calories' are numeric and within logical ranges. If invalid data is entered, the class should handle these cases gracefully by prompting the user or rejecting erroneous input. Inline comments integrated into the code will clarify the rationale for each data type, aiding future maintenance efforts.

In terms of control structures, the program should employ conditional statements (e.g., 'if' or 'switch') to validate data types and ranges. Expressions or statements within setter methods or constructors should update class attributes appropriately. Comments should explain how these control structures ensure data validity and contribute to the integrity of the recipe management system.

Overall, designing the Ingredient class with well-chosen data types, validation logic, and clear inline comments is essential. This foundational class supports the broader objectives of the final project: creating a robust, user-friendly application that manages recipes efficiently through parameterized ingredient data, facilitating both maintenance and scalability.
