[JohnnyBigodes]

That independent debt collector made my day ;). It is again a great video... Thank you

[JoseManuelCornelio]

These videos are so dense that I really have to take some time to digest the content before moving on to the next one. This is better than any paid course out there so far.

The way instructor has describe the OOPS concepts with realtime examples and cases is really awesome.

[neozes]

Dude! This was amazing! The fact, that you have covered the topic from all angels was just spectacular. I just came here from another video, that just explained how to implement interfaces, without any context, especially... what damn problem is this utility solving. Thank you!

[dajanradovic]

great teacher, great examples and way of teaching. thank you for clearing up all these concepts

[Zubbee]

This is another mind opening lesson in my quest to learn PHP. I also think this is the lesson that is now compelling me to go back and look at some of the earlier OOP lessons to really link terms and concepts better. It has certainly started feeling like I'm taking a course in the University. Thanks Gio

[techatival]

Really liked the polymorphism example. Thank you!

After watching this video many times, I have finally got an opportunity to use it in one of my projects. I recognized the situation I was about to go into needed an interface to keep the system flexible for the future. I needed to build multiple types of XML requests. Using and interface, I only need one gateway class to pass the different XML request to. Thanks Gio!!

[sergeisurin]

A really good course, one that doesn't just go over the basics, what I've always hoped to see.

I think I've already said but I'll repeat: you are the guru for programming. Masterpeace!

I"m 2 years in software engineering and I would like to hear your opinion about learning design patterns in OOP: creational, structural, behavioral. How important they are?
