Research Essay: Introduction (Encapsulation's usefulness in object-oriented programming.)

-


Through encapsulation, object-oriented programming can be made safer. Several programming languages use object-oriented programming (OOP), including C++, Python, and JavaScript. Four pillars underpin this concept, which include Abstraction, Encapsulation, Inheritance, and Polymorphism. Encapsulation is defined as the packing of data and functions into one component (for example, a class) and controlling access to that component to create a "black box" out of it. (Pfeiffer, 2022). Among the advantages of encapsulation are hiding data, flexibility, and ease of reuse. Moreover, it is easy to change and adapt to new requirements with encapsulation. Encapsulation will be the focus of this essay in order to help the reader understand what it is and how it helps solve problems.

(Athena, 2019) This post will cover my experiences with software and hardware throughout my life. When I was 8 then I had used for the first time computer. I remember today when my dad came home with a mysterious metal box, the computer he brought back then was called a Commodore. Computers in those days looked completely different and games were run using "Datasette". In that moment,  my mind began to wonder how these devices worked. I was fascinated by the whole procedure of starting programs and games, and I wondered how it is possible that these programs exist and what they are.  Over the years, technology has developed so fast, and I was fascinated by computers and software all the time. This curiosity led me to write my first program when I was 14, it was a simple calculator created in an integrated development environment (IDE) - Microsoft Visual Studio. Of course, during my adventure with computer technology, I used a lot of software such as music processing and editi...
