Question
Which of the following would be a part of an OOP implementation of cars, trains, and vehicles?*requiredThe train class abstracts the vehicle classThe car class inherits from the vehicle classThe vehicle class implements the car classThe vehicle class encapsulates the car class
Solution
The correct answer is "The car class inherits from the vehicle class".
Here's why:
In Object-Oriented Programming (OOP), a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods).
The concept of inheritance allows you to build a new class using an existing class. The new class, known as the derived class, inherits the members of the class it extends.
In this case, "Vehicle" can be considered as a base class and "Car" and "Train" can be considered as derived classes.
So, the statement "The car class inherits from the vehicle class" is correct as per the OOP concept of inheritance.
The other options are incorrect because:
- "The train class abstracts the vehicle class" is incorrect because abstraction is not about one class abstracting another class. It's about hiding complex details and showing only the essentials.
- "The vehicle class implements the car class" is incorrect because in OOP, a class doesn't implement another class. A class can implement an interface.
- "The vehicle class encapsulates the car class" is incorrect because encapsulation is about bundling the data and the methods that work on the data into a single unit, not about one class encapsulating another class.
