OOP 3 Encapsulation

What is encapsulation in object-oriented programming?

• The process of inheriting properties from another class

• The bundling of data with the methods that operate on it

• The ability to define multiple methods with the same name

• The conversion of data types

What is the relationship between objects and methods in encapsulation?

• Methods are used to directly access other objects

• Methods are used to access an object's private attributes

• Objects can access each other's private attributes directly

• Methods are not related to objects

Which procedure is used to update the address of a Person object?

• getAddress

• setAddress

• getName

• setName

What is the role of the 'public' keyword in the procedures?

• It makes the procedure accessible only within the class

• It makes the procedure accessible from outside the class

• It makes the procedure private

• It makes the procedure static

What is the purpose of encapsulation in object-oriented programming?

• To allow direct access to all attributes

• To hide the internal state and require all interaction to be performed through methods

• To make all methods public

• To increase the complexity of the code

In the given class, which attribute is private?

• name

• address

• both name and address

• neither name nor address

What condition must be met for the `setName` procedure to assign a new name?

• The new name must be exactly 10 characters

• The new name must be between 3 and 20 characters

• The new name must be less than 3 characters

• The new name must be more than 20 characters

In the provided code, which keyword is used to define a private attribute?

• public

• protected

• private

• static

What is the main benefit of using private attributes in a class?

• To ensure that the attributes can be modified directly

• To make the code more complex

• To allow easy access to attributes from outside the class

• To protect the integrity of the data by restricting direct access

How can a private attribute be accessed from outside its class?

• By using a public method within the class

• By declaring the attribute as public

• By using a static method

• By directly accessing the attribute
