Management Information System (MIS) Practice Exam

Which of the following object-oriented programming concepts uses modules that allow programmers to group properties and behavior together?

1. A) Encapsulation

2. B) Inheritance

3. C) Class

4. D) Polymorphism

The correct answer is: C) Class

The concept that accurately describes the grouping of properties and behaviors is encapsulation. This object-oriented programming principle allows programmers to bundle the data (properties) and the methods (behaviors) that operate on the data into a single unit, known as a class. In encapsulation, the internal representation of an object is hidden from the outside, allowing for data protection and abstraction. This means that the class can restrict access to its properties and methods, exposing only what is necessary through public interfaces while keeping the internal workings private. Classes serve as templates for creating objects and inherently support encapsulation, but the focus is on the broader concept of how data and behaviors are combined within an object. While inheritance is about deriving new classes from old ones, and polymorphism refers to the ability to treat different classes through the same interface, encapsulation is specifically about the bundling and protection of the data and methods that make up the object.
