By creating public methods to access and modify private variables

[numberlist]

Use access methods
Accessor methods (getters and setters) are essential for manipulating private data in a controlled manner. They allow you to define rules on how data can be accessed and modified.
you can ensure that only valid changes are made.

Keep interfaces simple
For encapsulation to be effective, your class must expose a simple, clear interface. This allows other parts of your code to interact with the class without knowing its internal details.

Design your classes to provide only the italy cell phone number list necessary functionality, without exposing unnecessary internal data.

Protect internal data Ensuring that the internal state of a class cannot be inappropriately altered is crucial to code integrity. Implement validations on accessor methods to protect data.

Conclusion
Encapsulation is a fundamental practice in object-oriented programming that offers several advantages, such as data protection, ease of maintenance, and reduced code complexity.

By encapsulating variables and methods, you not only ensure that the system remains secure and organized, but you also make it easier for the software to evolve and adapt over time.
