It was designed to be platform-independent and easy to learn, and it has become the primary language used for Android app development. Java is one of the oldest, most popular, and well-known object-oriented languages. Object-oriented languages can be subdivided into categories depending on their particular type of system, also referred to as static or dynamic typing. Real-world objects are used to model the state and behavior of real-world entities in your application. Each of these languages has different strengths and weaknesses, but they’re all object-oriented.īefore we go over the six OOP languages, let’s take a look at what an object-oriented programming language is.Īn object-oriented programming language is a programming language that represents the elements of a problem as objects, which contain data and behavior. Our blog will go through the six object-oriented programming languages commonly used today, including Java, C#, Ruby, Python, TypeScript, and PHP. Top List of Object-oriented Programming Languages

Polymorphism allows for more flexible code and a greater degree of abstraction. This is usually achieved through inheritance, where the child class can redefine the behavior of the members inherited from the superclass. It is the ability of an object to take on different forms or be polymorphic. This allows for code reuse and a more concise way of developing software. The child class then gains all the members of the superclass, including data and behavior, unless they are overridden in the class. InheritanceĪllows one class, called the base or superclass, to be inherited by another class, called the derived or child class.

Encapsulation allows the definition and implementation of interfaces between different objects. The object can then be assigned to a variable that can be passed around as if it is an element of code. The data and behavior should be made hidden from the other objects and the developer. The process of combining data and behavior together into a single unit is called an object. It is a set of rules and definitions that allows one to understand a topic or issue without actually knowing about it in person or how it was developed. Principles of Object-oriented Programmingįour principles of OOP that you should know before learning any object-oriented programming language include: Abstraction In other words, no two objects are the same. Individual objects have their own unique identity that distinguishes them from all other objects. It contains its own copy of each property defined in the class, and each method is executed independently on that object. An object can be thought of as a particular instance of a class. In object-oriented programming, you instantiate a class by creating an object. This class could include properties such as width, height, and color and other methods such as rotate and translate. For example, you could create a class named Shape that defines the properties and methods for all shapes. This class includes properties such as make, model, and year and other methods such as start, stop and accelerate.Ĭlasses can also be used to model abstract concepts. For example, you could create a class named Car that defines the properties and methods for all cars. Methods are like functions, except objects can invoke them.Ĭlasses can be used to model the real world.

Properties are like instance variables, except all objects of a class share them. In object-oriented programming, you create classes by defining a set of properties and methods. It defines the data and behavior that all objects of that type will share. ClassesĪ class is a template for creating objects. Two basic building blocks of object-oriented programming are classes and objects. That’s because object-oriented programming helps us break down the problem into manageable chunks, like “persons” and “calculations.” The program can then use each of these manageable chunks of code to do its thing.īuilding Block of Object-oriented Programming These are usually large programs that solve complicated problems. Object-oriented programming is the best way to create complex computer programs.

This also saves development time and makes programs easier to maintain because if there’s a bug or a defect, you can fix it in one place instead of having to search through multiple files looking for where the error occurs. Object-oriented programming aims to increase code reusability by creating different classes for different types of information, which allows developers to easily add features when they need them without having to change existing code. It is based on the concept that all items in a program such as variables, data structures, and functions should be treated as objects. Object-oriented programming or OOP is a type of computer programming in which the objects and their interactions with one another are considered central.
