Programación Orientada a Objetos

What is a class in object oriented programming?

• A class in object oriented programming is a database table

• A class in object oriented programming is a blueprint for creating objects.

• A class in object oriented programming is a variable

• A class in object oriented programming is a type of function

Define object in the context of object oriented programming.

• An object is a variable in object oriented programming

• An object is a function in object oriented programming

• An object is a comment in object oriented programming

• An object is a real-world entity that has state and behavior, and it is an instance of a class in object oriented programming.

What is the purpose of inheritance in object oriented programming?

• To prevent code reusability

• To allow a new class to inherit properties and behaviors from an existing class.

• To limit the functionality of the new class

• To create completely independent classes

How does encapsulation help in achieving data hiding in object oriented programming?

• Encapsulation helps in achieving data hiding by restricting access to the internal state of an object and only allowing access through the object's methods.

• Encapsulation only allows access to the internal state of an object through direct manipulation

• Encapsulation has no impact on data hiding in object oriented programming

• Encapsulation allows unrestricted access to the internal state of an object

Differentiate between class and object in object oriented programming.

• A class is used for storing data, while an object is used for defining methods.

• A class is only used in procedural programming, while an object is only used in object oriented programming.

• A class is a specific instance of an object, while an object is a general blueprint for creating classes.

• A class is a blueprint for creating objects, while an object is an instance of a class.

What are the advantages of using inheritance in object oriented programming?

• Inheritance does not allow for flexibility in modifying the behavior of classes

• Using inheritance can result in tight coupling between classes

• Inheritance leads to increased code complexity and maintenance

• The advantages of using inheritance in object oriented programming include code reusability and promoting a hierarchical relationship between classes.

How does encapsulation promote the concept of information hiding?

• Encapsulation restricts access to certain components, preventing the direct modification of data and promoting the concept of information hiding.

• Encapsulation exposes all components, allowing direct modification of data and undermining the concept of information hiding.

• Encapsulation has no impact on access to components, therefore not affecting the concept of information hiding.

• Encapsulation only hides data from the developer, but not from external users, thus not promoting the concept of information hiding.

Discuss the importance of classes in object oriented programming.

• Classes are important in object oriented programming as they allow for the creation of blueprints for objects, encapsulate data and behavior, promote reusability, and help in organizing and managing code.

• Classes only create confusion and complexity in code

• Classes are not important in object oriented programming

• Classes are only useful for basic programming tasks

Explain the concept of access specifiers in object oriented programming.

• Access specifiers in object oriented programming define the size of the memory allocation

• Access specifiers in object oriented programming control the speed of data processing

• Access specifiers in object oriented programming determine the color of the user interface

• Access specifiers in object oriented programming define the accessibility of classes, methods, and variables. The main access specifiers are public, private, and protected.

which of the following is not a principle of oops

• inheritance

• encapsulation

• polymorphism

• procedural programming
