In my first programming course, I asked my professor how important it is that I learn Object Oriented Programming (OOP). He replied by saying, if I want to program anything, I must learn OOP. Being a freshman then, I took that lightly until I started coding and did not understand what I was doing. It was then that I realized how important it is to learn about OOP and utilize the concept in my program. As students especially beginners in programming, we are so geared towards completing programming assignments, projects etc that we fail to really understand what is used to structure a software program which OOP is basically about.

I selected this specific blog post because it talks about OOP and what it entails. The blog explains OOP as a programming paradigm that relies on the concept of classes and objects. It provides the importance and reason for OOP. It also explains classes, objects, methods, attributes and provided some examples, code snippets and OOP structure. I believe that this is important to know especially for new programmers, to better understand, and help structure their programs as well as others. The blog also explains the principles of OOP which is inheritance, polymorphism, abstraction and encapsulation. It provides code snippets of how each of these principles are seen and employed in codes and programs. It also provides a table that summarizes each concept.

In this blog I learned more on inheritance that it supports reusability. I learned from previous programming class that subclass can inherit all attributes of its parents class and add more attributes but little did I know that subclasses do not have to redefine methods that are already defined in parent class. When a method is called, it goes up to the child parent classes to find where that method was defined. It used to be a common mistake in my programs as I would redefine methods from parent class in subclasses and I never clearly understood why I got errors.

Also, I learned on encapsulation that, it hides the internal software code implementation inside a class, and hides internal data of inside objects. After reading this, I am sure to employ this method to hide information that I would not want to change in my program or code. In the past, I wasn’t able to understand the difference between protected and public codes when I see them, other resources made it very ambiguous for me to understand. However, thus blog provided a simple, easy to understand difference between them. Public codes are those that can be accessed by other classes in the program and protected are those that can only be accessible to subclasses.

I hope beginner programmers will find this blog helpful. For continuous programmers, this blog will help broaden your understanding and knowledge of OOP like it did to me.
