OOP & Design Patterns - Polymorphism - Compile-Time (Overloading) vs Runtime (Overriding)

You are designing a plugin system where plugins can extend base functionality by overriding methods, but also provide utility methods with the same name but different parameters. Which approach best balances flexibility and maintainability?

AUse only overriding and delegate utility methods to separate helper classes.

BAvoid overloading entirely to prevent confusion; rely solely on overriding with different method names.

CImplement all plugin methods as overloaded methods in the base class to simplify interface.

DUse method overriding for core plugin behavior and method overloading for utility variations within the same class.

Step-by-Step Solution

Solution:

Step 1: Identify roles of overriding and overloading
Overriding enables runtime polymorphism for core behavior; overloading allows compile-time flexibility for utility methods.
Step 2: Analyze design trade-offs
A balances dynamic behavior with method name reuse for utilities, improving maintainability. B reduces flexibility and may increase method count. C overloads core behavior, losing runtime polymorphism. D separates utilities but complicates usage.
Final Answer:
Use method overriding for core plugin behavior and method overloading for utility variations within the same class -> Option D
Quick Check:
Overriding for behavior, overloading for utilities balances design [OK]

Quick Trick: Override core, overload utilities for clean design [OK]

Common Mistakes:

MISTAKES

Avoiding overloading due to fear of confusion
Overloading core behavior losing polymorphism
Separating utilities unnecessarily complicates API

Trap Explanation:

PITFALL

Candidates often fail to combine overloading and overriding effectively in design.
