I've already built the biggest part for my MSc thesis project because of you... Don't know how grateful I am for your contributions, not only for me but also to the developer community.

[meanstoandend]

I very much appreciate and enjoy your content and the way you teach. I’ve been learning a lot from you and just wanted to say thanks for doing what you do 🙏

[hitstick]

Could you do the same video but with interfaces? I feel like they have become more complex with each Java release. You seem to have such a great understanding of it

[abdedaimehicham]

Thank you for your explanation
I have one remark about the method parse i think you can imporve it by avoiding boilerplate code and leagcy classes to read file and you can use Files.lines and It will return a stream and you can do filter on this stream and create another method to test the regex and apply this method on filter method .

Amazing, I saw that there are abstract classes but never knew what are they really for. Thank you for sharing

[TkmMusicProduction]

Very very clear explanation!, with real example, yes, thats true, you will never see Dogs, Cats, Squares, rectangles, foo and bar in production!, you will see business procesess like this!.. Thank you very much for your useful video! 👍👍

[dudnik]

Great example, thanks for breaking it down. Cheers.

Hi @Amigoscode, I have been following your content for quite long. It's really incredible work you are doing to help all of us. Thank you very much. And I always face challenge in understanding the existing code (mostly I work on Java) when I am moving across new projects. I really appreciate if you can prepare a video on how to understand existing code base of JAVA. Thank you once again.

[snoopie]

Thanks for going further than the "Animal" "Shape" stuff. I never understood how to "Actually" do it with those examples.

Wouldn't it be better to have default implementation of clean function (in this case only return input) in abstract class and then override it in child classes only where you want new functionality?

[mandanakhashayar]

The very clear explanation. Thank you. Even we can have default implementation for method clear in abstract class. That can help us to modify the code much easier when the method is just needed to be implemented by some classes. Thank you so much for your useful videos.

[dansmar_]

This is a great explanation, thank you so much!

[wgalloPT]

i so thankful for everything you do over here!!! ALWAYS amazing. Thank you

[DebugWithAdam]

Of course it makes sense as always. Thank you so much man.

[johnronaldraviz]

I never thought of using abstract methods declared on an abstract class. Thanks a lot.

[zimmtheking]

great example and thanks for not using "cats and dogs"!!!
please more of this pragmatic and uselful stuff.

[isahbala]

Funny, but more interesting than Java classes in College! :)

[cesarhinojosa]

I was so annoyed at being taught complex design patters and design principles with squares, circles, apples, bananas, etc. Thank you for this very helpful example!

Im preparing for interviews in January so now Im just browsing youtube reviewing stuff 😄

Since you are producing/exporting reports, you could implement the visitor behavioural pattern on the abstract class and implement a visitor interface that accepts an export feature
