Topic 6.5: Working with Methods and Encapsulation - Apply encapsulation principles to a class Flashcards
What is the purpose of data hiding in encapsulation?
This in encapsulation ensures that the internal data of a class is hidden from external access. It is achieved by declaring data members as private.
How does encapsulation improve code maintainability?
Encapsulation allows changes to be made to the internal implementation of a class without affecting other classes that use its public interface. This reduces the risk of introducing bugs or breaking existing code.
this in encapsulation ensures that only the necessary information is exposed through the public interface of a class, while hiding the internal details and implementation.
What is the purpose of information hiding in encapsulation?
What is one advantage of encapsulation in terms of code reusability?
Encapsulation promotes code reusability as classes with well-defined interfaces can be easily reused in different contexts.
How does encapsulation provide flexibility in changing the internal implementation of a class?
Encapsulation allows for easier refactoring and adapting to changing requirements by allowing changes to the internal implementation of a class while keeping the public interface unchanged.
What is the purpose of information hiding in encapsulation?
this in encapsulation ensures that only the necessary information is exposed through the public interface of a class, while hiding the internal details and implementation.
Why is it important to hide the internal details of a class?
Hiding the internal details of a class ensures that the implementation is not exposed, promoting better software design, security, and modularity.
It also prevents dependencies on the internal structure of the class.
What are the benefits of information hiding in encapsulation?
this allows for easier maintenance and modification of a class, as changes to the internal implementation do not affect other classes. It also enhances security by restricting access to sensitive information.
How does encapsulation maintain data integrity?
This ensures data integrity by allowing access and modification of data only through the defined public interface of the class. Private data members prevent direct external access.
Having control over data access and manipulation allows the class to:
- enforce validation rules
- perform necessary checks
- maintain the consistency and integrity of the data.
Why is it important for a class to have control over how data is accessed and manipulated?

What is the role of the private access modifier in encapsulation?
The private access modifier restricts direct access to data members from outside the class, enforcing encapsulation and data hiding.
this allows for easier maintenance and modification of a class, as changes to the internal implementation do not affect other classes. It also enhances security by restricting access to sensitive information.
