▷ What is object -oriented programming (poop)?

Object -oriented programming (POO) is a programming paradigm that uses «objects» and «classes» to structure the software. This allows you to organize the code in modularized units, facilitating the reuse and maintenance of the code. It is based on 4 fundamental principles, that is to say: encapsulation, inheritance, polymorphism and abstraction.

Poo focuses on the modeling of concepts and entities in the real world, encouraging a more intuitive and flexible approach in the development of the software. It is one of the most popular IT paradigms, used in many fields, from the development of web and furniture applications, to the creation of video games. The poop is based on the idea of modeling the objects of the real world and of using them to create complex applications.

In this type of programming, an object is an autonomous entity, which contains both the data (variables) and the methods (functions). These objects can communicate with each other, modifying information and requesting services. The poop is a strong paradigm, which allows you to write a more modular code, easier to maintain and easier to understand. In addition, object -oriented programming helps you organize your code into classes and divide the application into logical modules, making the development faster and efficient.

Poo helps you to enter the heart of programming, really understand how the applications you use daily or even create your digital creations. You can learn the poop with us, to the Newtech Academy, through a programming course oriented to the object.

The fundamental concepts of the object -oriented programming

In programming oriented to the object, there are four fundamental concepts:

1. Classes: Skeletons, architects of object -oriented programming. They define the «type» of an object, just as an architectural plan defines the structure of a building. In a class, you describe the attributes (or properties) and methods (actions) that an object can have.

2. Objects: The concrete courts of the classes. If a class is a plan, then an object is a building built according to that plan. Each object has its own specific attributes (such as color, size, etc.) that distinguish it from other objects of the same type. In programming, an object maintains the state and can perform actions with the methods defined in its class.

3. Methods: The functions defined in a class that describes what an object can do. They are like the instructions that an object follows to perform a certain task. For example, in a «car» class, you may have methods such as «accelerating» or «stop». Each object created in the «car» class will be able to perform these methods, that is, accelerate or stop.

4. Incapsulation: Data protection within a class, preventing direct access to them. It is like putting a protective wall around the attributes and methods of a class. This is done using access changes as «private» or «protected», which controls how they can access or modify attributes and methods. Encap helps prevent unauthorized changes and maintains the integrity of the object.

Programming languages oriented to the object

To advance in the charming world of object -oriented programming, it is necessary to know the programming languages that adopt this style. Below I prepared 3 of the most famous:

Python

Python is a programming language oriented to the objects created in 1991. It is an interpreted language, which means that it has the source code interpreted directly from the computer.

Python is used to develop desktop applications, web applications, mobile and system applications. This technological giant has become extremely popular for the development of artificial intelligence and automatic learning, thanks to its strong and easy to use bookstores.

Java

Java is one of the most popular programming languages oriented to the object. It was created by Sun Microsystems and was launched in 1995. It is an compiled and interpreted language, whose source code is transformed into a low -level language, called bytes, which is therefore interpreted by a Java virtual machine (JVM). Just like Python, Java is used to develop desktop applications, web applications and mobile applications.

C ++

C ++ is a programming language oriented to the objects created in the 1979 years. It is an extension of language C, which is a procedural language.

C ++ is a language compiled with the source code transformed into a low -level language, called the machine code, which is then performed by the computer. It is used to develop desktop applications, video games and system applications.

Object -oriented programming – Design models

When it comes to an object -oriented programming, the design models are essential for efficient and easy development. These are standardized solutions to common problems that occur during software development. Subsequently, we will discuss three of the most used design models in object -oriented programming.

Singleton

The Singleton model is one of the simplest and commonly used design models. It refers to the creation of a single instance of a class, to which it is therefore possible to access from any place of the application. This model is useful when it is necessary to have a single instance of a class to avoid creating more courts that would occupy more memory.

Factory

The factory model is used when you want to create objects without exposing the logic behind their development. It allows you to create objects without specifying the creation of the exact class of the object.

Observer

The Observer model is used when you want to automatically notify a number of objects when something happens in another object. It is commonly used in user graphic interfaces, where you want to automatically update a number of objects when the user interacts with the app.

The use of design models in software development can offer multiple advantages, improve efficiency and facilitate the development process. Understanding these models is particularly important for software developers, as it helps them to create better and more reliable programs.

Practical uses of object -oriented programming

Here are the most common uses of poop:

Software development: Allows developers to create complex programs by combining different objects. In addition, Poo facilitates the development of modular software, which makes maintenance and updating easier. It also encourages the reuse of the code, which reduces time and development costs.

Mobile applications: Allow developers to create applications that can communicate with other external applications or servers. In addition, the programming oriented to objects facilitates the development of user interfaces and advanced features, such as vocal recognition and facial recognition.

Video games: Allows developers to create more complex games, with different features and levels. It also facilitates the development of graphics and animations, which makes games more interactive and attractive for users.

Our conclusion?

Object -oriented programming is like a complex puzzle. Classes and objects are the pieces, the methods are as the pieces interact and the encapsulation ensures that each piece remains in the right place. Using these concepts, developers can create strong and flexible software, which are easy to understand, maintain and extend.
