Object Oriented Programming: Abstraction Vs. Encapsulation

When it comes to programming "concepts" are often valued by interviewers as a way to demonstrate you understand how things work, not just how they operate. But as Sopya16 found out, sometimes they are just a way for a manager to try and feel superior.

Abstraction and Encapsulation for most people will be very much the same thing, and since a big part of each is separating the programmer for the "how" so they can focus on the "what" makes it ironic that a manager would judge you for not understanding the intricacies of these two terms.

The guy in the video is wrong.   Encapsulation does indeed have to do with hiding, especially implementation details.   Abstraction is NOT about hiding implementation details.  You confuse the words twice in the video.  Abstraction is a way of modeling a real world object with minimal information.  Example: Abstraction of an employee in the real world means you can define it in a programming language with only what is necessary.  What is not necessary?  An employee class does not need to include, for example, that the employee is composed of cells, nerves, blood, a heart, and maybe a soul.  

It's kind of funny because it's easy to see how one person watches a video like this, then goes and records their own video.  So instead of just one misinformed person, you now have two misinformed people, sharing misinformation.  And the misinformation blossoms exponentially.

Encapsulation: Putting an object inside another.E.g. Car class encapsulates engine class.
Abstraction: Exposing only methods you want seen.

language and concepts are 2 different things, encapsulation, abstraction etc can be formed across in different languages, either c, c++, etc...

Sooo... placing something behind a wall for the purpose of making it invisible from a users perspective ISN'T hiding said something? l0l.

C++ doesn't have garbage collection.

[BrandonWirtz]

@Kouthan Yes, and you can build assembly code that is "encapsulated" for use in other languages... I didn't mean to imply that Encapsulation was only for OOPs just that was what the question was about.

[AthanasiosK]

Actually I believe that you can have encapsulation in C too. You can use compiled files and just give an other file with the interface so that others know how to interact with it.

[robstokes]

Did he say garbage collection has been abstracted in C++? C++ doesn't have automated grabage collection. If I use a pointer and don't delete it I wll get a memmory leake. C# && Java && most every other high levle language have abstracted memmory managment better.

[usmansbk]

abstraction is hiding information from client, encapsulation is putting together a method to interact with the hidden information without bothering about the details.

[HemaDarshiniSelvaraju]

if you cant see it mean you are hide from it that concludes why it says its being hide. as simple as it is :D

[BrandonWirtz]

@TDmillerproduction What about C#? In all Object Oriented Programming the terminology would be the same.

[TDmillerproduction]

@BlackwaterOpsDotCom Do you still have plans to do a video on pudcenter? Sorry if i keep asking you on youtube and twitter, you said you would have it this week. I understand you don't do youtube full time and you are very busy.

[BrandonWirtz]

@TDmillerproduction yeah, these are from my back log I have a bunch of vids that need to get edited.

[KhanSlayer]

Great video. Your ending sounded like a shot at C++. Lol. I know that was not your intention though.

[sourabhbagrecha]

The percentage of dislikes says it all.

[TDmillerproduction]

@BlackwaterOpsDotCom I can edit videos for you, but for a small fee :)
