Object Oriented Programming Concepts

What is inheritance in object-oriented programming?

• Inheritance is a mechanism where a class inherits properties from an interface.

• Inheritance is a mechanism where a class inherits properties from a superclass.

• Inheritance is a mechanism where a new class inherits properties and behavior from an existing class.

• Inheritance is a mechanism where a class inherits properties from a subclass.

Explain the concept of encapsulation.

• Encapsulation refers to the process of converting data into a format that can be easily shared across different classes.

• Encapsulation is a technique used to prevent data from being accessed by unauthorized users.

• Encapsulation is the process of breaking down a class into smaller units for better performance.

• Encapsulation is bundling data and methods into a single unit (class) for data hiding and abstraction.

How are class relationships defined in OOP?

• Class relationships in OOP are defined through aggregation, encapsulation, and polymorphism.

• Class relationships in OOP are defined through abstraction, delegation, and instantiation.

• Class relationships in OOP are defined through coupling, decoupling, and encapsulation.

• Class relationships in OOP are defined through inheritance, composition, and association.

What is method overriding and why is it used?

• Method overriding is used to confuse programmers by providing unnecessary complexity.

• Method overriding is used to provide a specific implementation of a method in a subclass that is already provided by its parent class.

• Method overriding is a way to hide the functionality of a method in a subclass.

• Method overriding is used to prevent inheritance in object-oriented programming.

Give an example of inheritance in a programming language.

• Java

• C++

• Python

• HTML

Discuss the importance of encapsulation in OOP.

• Encapsulation in OOP helps in achieving data hiding, abstraction, and modularity, making the code more organized, secure, and easier to maintain.

• Encapsulation does not contribute to code organization

• Encapsulation in OOP leads to slower performance

• Encapsulation makes code less secure

Describe the different types of class relationships.

• Association, Aggregation, Composition, Inheritance

• Generalization

• Association

• Dependency

Why is method overriding important in OOP?

• Method overriding enables polymorphism and allows subclasses to provide specific implementations of methods from their superclass.

• Method overriding causes runtime errors

• Method overriding reduces code flexibility

• Method overriding leads to code duplication
