Abstract Classes vs Interfaces (Java)

A simple example that demonstrates the use of both Abstract Classes and Interfaces. The two can be used in many different ways, either exclusively or in combination. We chose to keep them separate in order to demonstrate the main differences.

I've learnt more in 9 minutes than my 3 hour long lecture in school. Thank you!

Hands the BEST tutorial on Abstract classes v.s. interfaces!!! The way you delivered concept with wrestlers was a stone cold stunner to me and I NEVER comment on Youtube videos. please keep doing what you're and thanks for the truth

[jeremiahnji]

I cannot describe how beautifully you explained these two very confusing concepts. I won't be confusing either of them ever again.

[reubenrajeev]

Love how you went straight to the point 1 minute in. I don't why people always try to take an hour to explain what exactly things are.

[TTOSWE]

I love how you can come from a 4 hour lecture on this without understanding a single thing and watch 10min video and understand everything. Thank you, good sir!

THIS VIDEO WAS SO GOOD, IF I OWNED A UNIVERSITY, I WOULDA HIRED YOU IN HEARTBEAT

[ReixScarlet]

I am paying a stupid amount of money at college for this and yet you did a better job for free, thank you very much!

[MIDNightPT]

Using wrestlers for the classes, that is so dope!!! That made this video so much more interesting as well

[SIDrockstar]

Man you are the hero the world of programming has but does not deserve. Loved that explanation, cleared all my doubts. Thanks a bunch!!

[muazammukaram]

thank you so much....my PhD professor wasnt able to explain this to me. bless you man.

I have been developing in Java since 1996, never saw a better explaination. WELL DONE SIR.


BTW, I am going to start using Wrestlers for my presentations from now on. Starting with Crusher, then Mad Dog Vashon, Nick Bockwinkel, etc Long Live Amercian Wrestling Association :-)

You're doing the world a disservice by not making more videos. You rock!

[alwaseem]

Trust this, I know the whole concepts and i got shocked when i watched this !! you are a genius guy. Best Ever

[reverendumrandom]

I have wasted 4 hours reading articles and papers which explain interfaces and abstract classes and still yet to understand. You put those articles and paper to shame by explain this concept in just 10 mins and immediately understood it. Will subscribe.

Its 2024 and your video makes more sense than my prof ... good job btw🎉

[zivkostoimcev]

You deserved my like and save!! In less than 10 minutes i figured it out better than my Professor explained. Well done! :):)

[moloiteboho]

I haven't finished the video and I know it's 5 years old but thank you so much... It really helped.

[techbrojoe]

Really helpful. I've read about both interfaces and abstract classes and it never made complete sense. Really liked the wrestling analogy. Made a lot of sense and I can define what they are now.

[qtech]

This dude just saved me 3 hours during the night!!
Thanks BRO!

[vanamutt]

it's been almost 5 years since you uploaded and it is still the best video explaining this topic.
