i jumped randomly into the video, at 10:35 and i already have an issue.... sorry, but since when do classes inherit interfaces? multiple inheritance works only between interfaces. one interface can inherit multiple interfaces. classes have the obligation of IMPLEMENTING interfaces. only thing you can do is mimic multiple inheritance is by using functionality implemented by other classes and exposing this through your instance, which actually is called composition. so the statement that you can inherit multiple interfaces in a class is incorrect sorry...but finding an error on the first thing i see makes me not want to listen to the rest of it

You sounds more accurate. But composition is not a very familiar term in C# and what I shared is more popular. Anyways, thanks for correcting me.

becz deligates are meant to be used from outside classes. They work as a representative of things happening inside class.. So that anyone who wants to use them do not need to create instance of that class to use the delegate. instead they can directly call it and use it.

This video leaves me feeling quite discombobulated after listening to its definitions of the terms abstraction and encapsulation!! The video gives the defintion of abstraction as "Showing only required things". But that definition matches the Wikipedia definition for encapsulation, Wikipedia states encapsulation as being "the limiting of direct access to some of that data". I'm familiar with a very different definition of abstraction, which is the one you'll also find in the Webster dictionary, which is "disassociated from any specific instance".

Thank you for your nice tutorial. I am finishing the first hour. For the moment I have two little notes. I think members of the interface do not have access specifiers and I think I have seen books saying that interfaces can also have property members and events. I also think that the main reason for boxing and unboxing was to achieve universal data type - object, which could be send as params to any class ctors and methods. Then generics came and send those to the unemployment department.

I am still confused in encapsulation. Can you please explain more detailed manner. Hope you answer my question.thanku
@interviewhappy
2 жыл бұрын
Hi Sandhya, private int empExperience is a field/ data. If it is public then it will be accessible outside the class and then it will be less secure and then there is no need of property. Properties are like functions and fields are like data. As per encapsulation definition, Function(property) and data(field) should be wrapped together to make the data secure and flexible. Don't get confused. Just remember always use public properties to access private fields as per OOPS concepts.
