You're designing a software system where you need to model different types of vehicles. Explain how you would utilize OOP concepts such as inheritance and polymorphism in this scenario.
- Abstraction for code reuse and Inheritance for encapsulation
- Encapsulation for security and Abstraction for complexity
- Inheritance for code reuse and Polymorphism for flexibility
- Polymorphism for security and Inheritance for flexibility
In this scenario, Inheritance can be used to model the common attributes of vehicles in a base class, and Polymorphism allows you to use a single interface for various types of vehicles, enabling flexibility and maintainability.
