Object-Oriented Programming (OOP)
What does Abstract class refer to?
Difficulty: Hard
About this MCQ
This Hard Object-Oriented Programming (OOP) question asks: What does Abstract class refer to? The correct choice is A. A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Object-Oriented Programming (OOP) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Object-Oriented Programming (OOP) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Object-Oriented Programming (OOP) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses. ✓
- B. An OOP principle that hides complex implementation details and exposes only essential features.
Why not B: “An OOP principle that hides complex implementation details and exposes only essential features.” is not A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses..
- C. An OOP principle that bundles data and methods together while restricting direct access to some components.
Why not C: “An OOP principle that bundles data and methods together while restricting direct access to some components.” is not A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses..
- D. The ability of a subclass to provide a specific implementation of a method already defined in its parent class.
Why not D: “The ability of a subclass to provide a specific implementation of a method already defined in its parent class.” is not A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses..
Correct answer
A. A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses.
Explanation
A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses option A is the accepted answer to What does Abstract class refer to Option B An OOP principle that hides complex implementation details and exposes only essential features is a different value from A class that cannot be instantiated on its own and may contain abstract methods to be implemented by subclasses Option C An OOP principle that bundles data and methods together while restricting direct access to some components is a different value from A class that cannot be instantiated on its own and may contain abstract methods to be.
