Bro this was the heaviest video of all till now ! Literally my brain just exploded ! But extremely simple and direct - So thank you for such a badass of a teacher
Wow, I'm glad I found your channel. You style is crystal clear and to the point. Although I'm taking other classes you clarify the points I was having trouble with. Thanks man!
really thx bro, though i'm watched some videos about generics, i'm still struggling with its use, here's some examples also other videos i watched but i'm not got a good understanding until you open the ArrayList class, everything is clear, i got the key point , this is really a nice video
Finally after spending 2 days reading the chapter and going over rigerious examples and still being clueless, I've understood generics. Love the channel name 😁
i am a fellow bro 😎, bro code plaese keep creating videos about java, there are very less content on youtube about java, everyone is posting videos about python , javascript but no one explaining java🥲 , thank you bro.
Can you create a generic arraylist to hold multiple types, for example: ArrayList newList = new ArrayList(); ??? Thanks for video, explained very well.
Well, Technically yes we can but there are so many disadvantages when using Object class, But if we use Generics its not complicated as Object. And also Generics is flexible and safe. At the same time, when we are working with Object it requires type-casting which lead us to so many errors.

thank you so much
love u bro
forever subscriber
Single-handedly taught me Generics and helped me complete an assignment in 30 minutes. Epic!
The best tutorials, I've ever seen on YT, thx bro!!!
I always go through one of these videos before starting my bootcamp lessons. It makes everything so much easier to get into.
Let start a campaign to give bro best teacher on youtube award !!!!!
❤❤❤❤❤❤❤ .
Excellent tutorial video about generic classes and methods!
That 1 dislike is from bro himself, just to keep himself humble... ;)
Bro this was the heaviest video of all till now ! Literally my brain just exploded ! But extremely simple and direct - So thank you for such a badass of a teacher
a lot of new stuff but really well explained, thanks!
My professor sucks and ever since I started coming here instead of their lectures, my grade went from a B to an A. Thank you Brofessor!
You, my dear Sir, are a legend. Thank you so much for all these incredibly useful instructional videos.
Thanks, I finally understand Generics, some code training/bootcamps explain it really complicated.. but with you i realized it's just that simple.
you have really the best tutorials I have ever seen, thank you. greetings from germany
very clear and comprehensive. thank you again.
Well said Bro, you did exactly what we want. The Duration with perfect explanation, great effort that you spend on it. It pay off man. Good Luck ...
concept cleared 🙌 Thanks Bro...and you have an unique way of explaining the things.
This would be the best java tutorial videos out there. Thank you bro
Your code is so clean. You really know what you are doing!!!!
well explained especially that part of where you can use 'Thing' instead of 'T' clears the mystery behind why is it always T,E or S.
Thanks again for another relatively simple concept explained in a brilliant way.
You are so smart to simplify such big task in a simple ways
Thank you bro!
Of Eritrea 🇪🇷
You are the best !!! Thanks for lessons in 2023
Good job bro. That's exactly how you teach sth. I'm very glad that I found this amazing channel. Keep going on
Wow, I'm glad I found your channel. You style is crystal clear and to the point. Although I'm taking other classes you clarify the points I was having trouble with. Thanks man!
this channel is a gold mine
Thank you so much for your simplified explanation . Straight to the point.
most helpful generics video on the internet. hands down
Really the best tutorials on TH-cam, that I've seen, keep up the good work Bro!
I was rejected in interview cause i didnt know what is generics and i saw that in their code xd, i saw many in a generic method. Thx
Self learning but I understand easily ,this guy is awesome...
I just learned more from a twenty minute video than a two hour lecture from my professor. You have a new bro.
Thank you for this very helpful video
Wow! Generic is so damn useful. I wish i saw this video yesterday lol but still, better than never. Well explained too
wow that's a lot of stuff in one tutorial 🤯👍
The best video for Generics I have ever seen, and the examples are pretty nice!
unparalleled at teaching, thanks bro
THE BEST EVER EXPLENATION OF GENERIC CLASS AND METHODS IN TH-cam HISTORY🤣
really thx bro, though i'm watched some videos about generics, i'm still struggling with its use, here's some examples also other videos i watched but i'm not got a good understanding until you open the ArrayList class, everything is clear, i got the key point , this is really a nice video
Very nice video. You have a nice way of explaining programming concepts.
what the hell so good java tutorial i ever saw in youtube. thank you very much!
Finally after spending 2 days reading the chapter and going over rigerious examples and still being clueless, I've understood generics. Love the channel name 😁
Yes, his chanel is very good!
His channel is not generic
thanks for teach us
Very clear explanation. My first clear understanding comes from you. Thanks a lot. ;)
Great explanation of an important topic. Thanks Bro!
Thank you for making this video, it was very helpful and informative! I appreciate it.
Great
I really understand what is arraylist😊
i am a fellow bro 😎, bro code plaese keep creating videos about java, there are very less content on youtube about java, everyone is posting videos about python , javascript but no one explaining java🥲 , thank you bro.
Thx Bro I think you were descend from the sky 😀. We are waiting for more tutorials... Thank you
so helpful thankyou
Awesome 👏
please do data structure
love your content
best teacher on youtube❤❤
Thank you for this video.
Nice channel, nice english, nice elocution, nice explaining.
Phenomenal explanation, thank you
I learnt lot of things so far from the above 83 videos
Amazing! Easy to understand explanation to generics. Thanks bro.
Best tutorials ever, holy shit it's pleasant to learn looking your videos bro, keep going !
best channel with best tutorials out there!
I liked your end of the session music and fast forward music. What are those?
Well explained
Thanks alot
Thanks for making this tutorial. Appreciate it 👍
Generic : same method and class but you can use these method and class for any data type instead of one specific data type
This the guy that taught me how to code fr
I really like your videos. You explain complex concepts appears easy, thx man
Amazing! thanks for this awesome explanation, really appreciate your videos.
Wonderful!!
Great.
Instead of creating 4 classes, Why we haven't overloaded the constructors?
This was really helpful for my exams ,Tq broooooooooo
Very good explanation!! Thank u
That's so good for the basic bro ! Hope you do more a bout advanced like more complex generic methods. Hope you doing well bro
Great video! Just one question, how can you limit so you can enter only chars and strings?
There doesn't appear to be any easy way to do so since the Character and String classes are in different type hierarchies
@@BroCodez ok thanks, keep up the good work!
i swear all the videos 1-3rd comment is best video ever, but which 1 is the best?!
Very useful lesson , thank you sir :)))
Dam, these videos are gold! So helpful in my bootcamp.
"What the hell is an AtomicLong!!" had me ROTFL
Nice
Thanks Bro, this help me to easily understand the basic concept of Generics in Java
very good, the best explanetion in the word!!! (i'm from Brazil)
Very helpful! Thank you.
Thankyou so much
This video is sooooooo awsome.......
Thanks for the tutorial, Bro.
Can you create a generic arraylist to hold multiple types, for example: ArrayList newList = new ArrayList(); ??? Thanks for video, explained very well.
Let's Go!!!!! At the end of your Java Playlist!!!!
good video
Thanks a lot for this amazing tutorial.
this was helpful, exploded my brain, thanks
Fantastic tutorial! Thank you so much :)
You are awesome! Thanks for all the help!!
Nice, thanks
you didn't explain the use of the Wildcard ? in generics
Great examples!
very helpful, thank you
Best explanation...
The only problem is that we can't instantiate an array with generic classes.
Thank you, it's very helpful.
can we use Object class refer instead of Generic ? are they both the same? if not please explain.
Well, Technically yes we can but there are so many disadvantages when using Object class, But if we use Generics its not complicated as Object. And also Generics is flexible and safe. At the same time, when we are working with Object it requires type-casting which lead us to so many errors.
