Object-oriented programming · interview question

Multiple choiceMediumchapter-5-curatedpremiumoopabstract-classes
Answer and explanation
Correct answer
B. Use an abstract class 'User' with common methods and abstract methods for specific actions.
Why
Using an abstract class 'User' allows you to define common methods that all users share, while also requiring subclasses to implement specific actions through abstract methods. This approach balances shared behavior and flexibility for user-specific actions.
