We could then set the value of the properties defined in the class to describe my car without affecting other objects or the class template. We then create an instance of a Car type object, m圜ar to represent my specific car. Each object can have unique values to the properties defined in the class.įor example, say we created a class, Car, to contain all the properties a car must have, color, brand, and model. These represent specific examples of the abstract class, like m圜ar or goldenRetriever. This function is only helpful to objects of type Car, so we declare it within the Car class, thus making it a method.Ĭlass templates are used as a blueprint to create individual objects. These functions are defined within the class and perform some action helpful to that specific object type.įor example, our Car class may have a repaint method that changes the color attribute of our car. These classes define what attributes an instance of this type will have, like color, but not the value of those attributes for a specific object.Ĭlasses can also contain functions called methods that are available only to objects of that type. Classes often represent broad categories, like Car or Dog that share attributes. Some languages, such as JavaScript, Python, and PHP, all allow for both procedural and object-oriented programming styles.Ī class is an abstract blueprint that creates more specific, concrete objects. OOP languages are not necessarily restricted to the object-oriented programming paradigm. There are many object-oriented programming languages, including JavaScript, C++, Java, and Python. It is used to structure a software program into simple, reusable pieces of code blueprints (usually called classes), which are used to create individual instances of objects. Object-Oriented Programming (OOP) is a programming paradigm in computer science that relies on the concept of classes and objects.
