What Is Object-Oriented Programming?
Object-oriented programming is a paradigm that uses objects containing data to organize models instead of actions. Previous programming paradigms focused on the logic behind actions rather than the objects themselves. This paradigm assumes that what we actually care about are the objects themselves. Object-oriented design identifies the objects the designer wants to manipulate and designs the model around those objects. Objects include things like people (names, for example) to small widgets we find on our smart devices. These objects allow you to reuse code written for other functions and objects are mostly class based. Different classes are then modeled and organized by the logic that manipulates it, called a method. Subclasses are related objects that also share characteristics and methods to their parent class.
What's The Benefit?
Object-oriented programming languages reduce development time because you can reuse code and develop models based on previous objects. Objects also separate themselves to prevent accidental overwriting or influence from other programs. It's clean and efficient. A lot of languages are object-oriented programming compatible, but a few common object-oriented languages are python, java, ruby, Smalltalk, C++, Pascal, Eiffel, Visual Basic, and Simula. This framework also addresses common difficulties with procedural programming, including cumbersome code. Software development is smoother, and the code is clean. Major organizations switched to OOP languages a while back in an attempt to scale. Companies like Microsoft and platform environments like Delphi use object-oriented programming as a primary model.
Learn Object-Oriented Programming
Object-oriented programming concepts underpin some of the most common real-world examples of development. You likely already know at least one OOP language if you've studied computer science and even if you're self-trained. Understanding these principles allow software design that's faster and more scalable than procedural language programming. Objects arranged into class variables are easier to manipulate without worrying about coding the logic behind each and every procedure. Software systems now use a lot of these principles and proficiency puts you in demand with many computer science careers.
