Welcome back! Now that you've powered up your Spacecraft class with attributes and methods, let's dive into the concept of visibility. This lesson is all about understanding how to control access to the data within your classes using getters and setters.

Visibility is essential for protecting and managing access to your class properties. Specifically, you'll learn how to use:

• Public attributes, which can be accessed from outside the class.
• Private attributes, which can only be accessed within the class.
• Getters and Setters to access and modify private attributes safely.

In our Spacecraft example, we'll see how to define both public and private properties and how to create getters and setters. This ensures that other parts of your program can interact with your class in a controlled and predictable way.

Here’s a sneak peek at what we’ll be working on:

By mastering visibility, you'll be able to safeguard the internal state of your classes and prevent unauthorized modifications. This is crucial for writing robust and secure code.

For instance, imagine you have a financial application where you need to protect sensitive information. By using private properties and exposing them only through getters and setters, you can ensure that critical data is not accidentally or maliciously altered.

This skill is not just theoretical; it applies to real-world scenarios across different domains, such as software development, data security, and even game design. Understanding and using visibility controls effectively will vastly improve the reliability and maintainability of your code.
