Protected
The “protected” access modifier is a compromise between “public” and “private”. When a member of a class is declared as protected, it can be accessed within the class itself, by subclasses (or derived classes), and also by other classes in the same package.

Now that you understand the concept italy cell phone number list and access modifiers, let's see how to apply encapsulation in practice. Using these principles correctly helps create more secure and maintainable code.
Let's look at some ways to apply encapsulation efficiently, with clear examples.
Use access modifiers
As we discussed, access modifiers control the visibility of members of a class.
Use the “private” modifier to protect internal data from external access. This ensures that only methods within the class itself can access or modify that data.
The “protected” modifier allows subclasses and classes in the same package to access members. This is very useful when you need to extend the functionality of a class without exposing its internal details to the entire code.
