Now That You Have Some Experience Building Basic Single Class Applica

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. You will start to implement a first version of a more complex class and create a test class to put it through its paces. Go to the Start Here page and download the Stepping Stone code .zip for the starter code for this assignment. To complete this assignment, review the following documents:

In this assignment, the primary goal is to extend your programming skills by developing a multi-class application. Unlike earlier projects that involved a single class, this task encourages you to design and implement multiple classes working together to serve a cohesive purpose. Such an approach demonstrates your understanding of object-oriented programming principles, including encapsulation, modularity, and class interactions.

Initially, you are instructed to download starter code from the "Start Here" page provided by your instructor, which contains the foundational code necessary to build upon. This starter code, typically packaged as a ZIP file, offers a structure and basic functionality that will facilitate your development process. Begin by examining the code thoroughly to understand its existing components and how the classes interact within it.

Your task involves creating at least one new class that enhances or complements the existing code. For example, if the starter code models a simple system such as a shopping cart, your new class might represent an item, a user, or a payment process. Focus on designing this new class to encapsulate specific data and behaviors, ensuring it integrates seamlessly with the existing classes. Pay particular attention to defining appropriate attributes, methods, and constructors to realize the class's functionality effectively.

Subsequently, develop a test class dedicated to testing your new class and its interactions within the application. This test class should instantiate objects, call methods, and display outputs that verify the correctness of your implementation. Testing is crucial for identifying bugs and confirming that your classes work as intended when combined.

Throughout your development process, adhere to best coding practices such as writing clear and concise comments, maintaining proper indentation, and following naming conventions. These practices improve code readability and maintainability, essential qualities in professional software development.

Finally, compile your source files and run your application to observe how the classes work together in practice. Document your process, challenges encountered, and how you addressed them. This reflection reinforces your understanding of multi-class design and prepares you for more complex programming tasks.

By completing this assignment, you will demonstrate an increased competency in designing, implementing, and testing multiple interacting classes—an essential skill in object-oriented programming. This experience will lay a foundation for developing more sophisticated software applications in future projects.
