______represents the link between elements of OO design.
- A.
Cohesion
- B.
Coupling
- C.
Completeness
- D.
Sufficiency
Correct Answer
B. CouplingExplanation
Coupling represents the link between elements of OO design. In object-oriented programming, coupling refers to how closely classes or modules are connected to each other. Low coupling indicates that the classes or modules are loosely connected and can be easily modified or replaced without affecting the others. On the other hand, high coupling means that the classes or modules are tightly connected and any change in one may have a significant impact on the others. Therefore, coupling is an important factor to consider when designing object-oriented systems to ensure flexibility, maintainability, and reusability.Rate this question:
