What is object-oriented programming?


Object-oriented programming (OOP) is a programming paradigm that is based on the concept of objects, which can contain data and methods to manipulate that data. OOP is widely used in modern programming languages such as Java, C++, Python, and Ruby.

In OOP, programs are designed as collections of objects that interact with each other to perform tasks. Each object has its own set of properties and methods, which can be used to manipulate its data and perform operations on it. OOP is based on several key concepts, including encapsulation, inheritance, and polymorphism.

Encapsulation refers to the practice of hiding the internal details of an object from other parts of the program. This is achieved by defining the object’s properties and methods as private or protected, so that they cannot be accessed directly from outside the object.

Inheritance allows objects to inherit properties and methods from other objects. This allows for the creation of hierarchies of objects, where more specialized objects inherit from more general ones.

Polymorphism allows objects of different types to be treated as if they were the same type. This allows for more flexible and modular code, as different objects can be used interchangeably in the same program.

At, we have a team of experts who specialize in object-oriented programming and can provide homework help in a variety of OOP languages. Our team is well-versed in the principles of OOP and can provide customized solutions to meet the specific needs of each student.

To illustrate our expertise in OOP, here are some coding examples:

In Java, we can create a class called “Person” that contains properties such as name, age, and address, as well as methods to set and get these properties:

public class Person {
  private String name;
  private int age;
  private String address;
  public void setName(String name) { = name;
  public String getName() {
    return name;
  public void setAge(int age) {
    this.age = age;
  public int getAge() {
    return age;
  public void setAddress(String address) {
    this.address = address;
  public String getAddress() {
    return address;

In Python, we can create a class called “Rectangle” that contains properties such as width and height, as well as methods to calculate its area and perimeter:

class Rectangle:
  def __init__(self, width, height):
    self.width = width
    self.height = height
  def area(self):
    return self.width * self.height
  def perimeter(self):
    return 2 * (self.width + self.height)

In C++, we can create a class called “Vehicle” that contains properties such as make, model, and year, as well as methods to display its details:

class Vehicle {
    string make;
    string model;
    int year;
    Vehicle(string make, string model, int year) {
      this->make = make;
      this->model = model;
      this->year = year;
    void display() {
      cout << "Make: " << make << endl;
      cout << "Model: " << model << endl;
      cout << "Year: " << year << endl;
