Man, thank you so much for the great tutorial, I love the way you explain as well as the energy you put into you videos, learning from you a lot! Keep rocking!

Just want to let you know that your explanation is very good with great and clear examples. I'd love to see more abstract concepts being explained by you too, like using abstract class in concrete class in OOP designs, invariant and variant, observer vs observable, event-driven design, etc.

So Simple! Wow After a year and a half I got it! Dan's videos are really great to watch. I am learning Java but they translate to any language at a certain level.

Thanks so much for this, this was one of those concepts where I understood the theory but couldn't understand why I would use it or why it was so important. Your enthusiasm is infectious :)

Thank you so much. You really helped me understand it.

yeop. First language gives an edge.

ikr, no offense to Indians, my first full programming course was from an Indian and it was awesome, but Indians just seem to lack a sense of humor which for me is crucial for a teacher to keep the students going.

School is not really teaching people to be smart.Its to create industrial age employees. They taught people in a one way learning style and dislikes creative diverse ways of learning.

Right! People like him I would be happy to take a loan out and pay for this amazing teaching.

I have a question. If suppose I add another method into the dog class, which is an extended version of the animals class but this method does not exist in the basic animals class. I want to run that method in the same loop for (animals a: kingdom). I am assuming that is not possible.!
Horst koston (9 months ago)
can you not also do if( a instanceOf Dog){ execute method defined in dog class} ?
The Coding Train (2 years ago)
+Ranjan Nayyar It's possible but you would need to check if the object is a Dog object or not and then cast it as a Dog object. Something like if (obj.getClass().getName() == "Dog").
