Encapsulation - Principles of Object Oriented Design

A brief introduction to the principle of encapsulation in object oriented software. Without encapsulation, all of the code has access to all of the data. This creates three problems. You have to check all of the code to find the cause of an incorrect data value, you cannot change the data structure without checking all of the code to find out what will be affected; and you cannot re-use the code because it is built around the whole data structure.

Good summary. But lacking some visual representation so the viewer can follow what your talking about visually. Breaking it down a bit and showing pieces of code would be a very good idea.

@sikhzrule I know what you mean. I am surprised that this is one of the more popular views since all I did was stand there and talk. On other videos I did make an effort to give visual explanations too but they take more time to put together.

nice video, gave me a good understanding as to why you would use encapsulation in only 3:25 minutes, which i found other tutorials and vids didnt have.

a small code example would of been sweet though

@nut315 Thanks for your comment. Good point. I'll probably do a follow video with some examples.

Thank you very much! You helped me greatly :)

they call me a dreamer but it worked with this lecture b/c I was using my talent visualize the representation. :-))
