ITPEC FE Subject A April 2026 Question 37
ITPEC FE Subject A April 2026 — Question 37 of 60
Encapsulation — bundling data with the procedures that operate on it into one object, and hiding the implementation inside.
The two halves matter equally: the data and its operations live together, and the outside world reaches them only through the published interface. That is what lets the internals change without breaking callers.
Answer (b)
Why not others:
- (a) — describes abstraction / classification, grouping objects by common properties
- (c) — describes generalization, extracting shared properties upward into a base class
- (d) — describes inheritance, a subclass taking on the properties of a base class
Key rule: Encapsulation is about the boundary of a single object; inheritance and generalization are about relationships between classes.
