1. Encapsulation :- Wrapping up of data member (variables) and member function (method) together into a single unit called is known as encapsulation . 2. Abstruction :- It is the act of representung essential features of class without including the background details. ex :- switch board , etc. 3. Polymorphism :- It is the ability of an object to behave in different form according to the message passed to it. In java it is implimentes due to function ove loading 4. Inheritance :- It is the ability of an object to acquire the properties of another class.

What was good? - The video was excellent. - She has covered all the necessary points to understand the OOP. - The way of explaining things was so good. - The examples were also very good to understand it in the right way. Where improvement is needed? - You could have done the trial & error in coding i.e. Multiple test cases for an even better understanding.

After Studying java : Actualy in 6:09 " new Pen( )" creates an objects. An object is created first then a ref variable in created seapreatly which is then refred to an object . ie Pen pen1 ; new Pen( ); pen1=new Pen( ) are 3 seapreate statements which shows how an object is created and then refred thriugh an refrence variable.

[@ashishdavda4514]

Good explanation, but overloading does not depend on return type.

[@AnkitKumar-dc3jt]

You should show us the error which came in console when you missed creating default constructor and wrote copy constructor. Explaining the reason of that error would provide viewers a better understanding. By the way nice video and I have subscribed your channel.. 👌 We have to define default/non parameterized constructor by ourself if we have defined any parameterized constructor which you have defined as copy constructor here. But if we don't define any parameterized constructor then default constructor is created by JVM. Correct me if I am wrong. Also please don't confuse viewers by your words because each word you say is tightly linked to topic and we are learning from you and listening to each of your words very carefully. You mentioned in partial abstraction that you have created a function name animal but you later pointed to eat function of Animal class. But end of the day I have subscribed you channel and really thanks for the video.
