What is object-oriented programming?
Object-oriented Programming is a programming language that uses objects to store data and code. It is organized around objects rather than functions, making it easier for developers to create complex and scalable applications. It allows developers to reuse code, resulting in fewer lines of code and faster development times.
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, which contain data and code to manipulate the data. Encapsulation is the process of combining data and related operations into a single unit (or object) to reduce complexity and increase security. Inheritance is the process of creating a new object (or class) from an existing object (or class). This new object (or class) can then be modified to meet the programming needs of the user.
Object-oriented programming languages use inheritance, which allows objects to pass their attributes and behavior to other objects. Object-oriented programming languages are built on the concept of classes, which act as blueprints for objects. Object-oriented programming languages often support multiple programming paradigms, like imperative, functional, and declarative programming.

Question: How would you design a program structure that reflects object-oriented programming principles? Clues: • Object-oriented programming involves creating objects that contain data and functionality related to those objects. • Objects are used to interact with each other to perform tasks. • Object-oriented programming languages are designed to be modular and extensible. In pairs: Select and solve one of the tasks: A. In pairs, create a diagram that visually shows how two objects interact with each other based on the principles of object-oriented programming. B. In pairs, create a written description of how a program structure could be designed that reflects object-oriented programming principles.
What is encapsulation in object-oriented programming?
- A mechanism that restricts access to methods and variables within a class
- A mechanism that allows one object to acquire the properties of another object
- A mechanism that allows objects to access each other's methods and variables
What is inheritance in object-oriented programming?
- The ability of a subclass or child class to inherit properties and behaviors from its parent class or superclass
- The ability of an object to acquire the properties of another object
- The ability of objects to access each other's methods and variables
What is polymorphism in object-oriented programming?
- The ability to use a single interface for multiple forms (types) of an action or behavior
- The process by which one class acquires the property (methods and fields) of another
- Creating duplicate copies, in memory, based on prototype
What is abstraction in Object-Oriented Programming?
- It refers to hiding unnecessary details while showing only essential information
- It refers to acquiring the property (methods and fields)of another
- It refers creating duplicate copies, in memory, based on prototype
