NEW QUESTION 14

Which three items are benefits of encapsulation? (Choose three.)

• A. restricted access
• B. flexibility
• C. maintainability
• D. performance

Answer: ABC

Explanation:
Encapsulation is the packing of data and functions into a single component. In programming languages, encapsulation is used to refer to one of two related but distinct notions, and sometimes to the combination thereof:
* A language mechanism for restricting access to some of the object's components.
* A language construct that facilitates the bundling of data with the methods (or other functions) operating on that data.
Incorrect:
not E: Encapsulation is one of the four fundamental OOP concepts. The other three are inheritance, polymorphism, and abstraction.

• A. Execute code only when an exception is thrown.
• B. Break out of the error handler.
