A quick look at the concepts behind OOP.

It doesn’t matter if you’re a software developer with very less or no experience, or a more experienced developer - you’re expected to know what OOP concepts are (at least from an interviewer’s perspective).

So in this 2-part series, I’m going try to explain the basic concepts of OOPS in the simplest way possible, tackling each concept in a question-answer (Q-A) format, just like in interviews.
