The best person on YouTube that explains java in such a great way

[keionvergara]

you were the reason i got a 5 on my ap comp sci A exam!! you truly have impacted my education and taught me more than my highschool teacher did in 5 months !

[Nanagos]

I recently found out about Records but there are just no good tutorials about it. I'm glad you made one now.

[libertymedicalcommunicatio]

Congrats on almost reaching 100K. This one should put you over the top.

[arnddeshives]

There is a lot of content like this out there, but you are so much better than the rest in terms of tempo, order, quality and presentation, thank you so much! I started studying CS half a year ago and your videos are 5x quicker at explaining the same thing than my prof. Although sometimes there is some depth missing, but it's good that your videos don't get lost in that, that's what makes it so good. Maybe it would be great if there was a playlist for in depth knowledge as well though.

please never stop making videos, these are so helpful!

[huskydreaming]

I am advanced in java but it is great to see someone explain it so concise. Amazing explanation on these types of videos. Keep it up!

[shankar]

Never thought learning Java would be such a pleasure. A decade ago, I was frustrated with the Java Reference book and left learning java and continued with my day job in DB language. Now, I am learning java without any issues with the help of youtube. Thanks to the youtube community.

[BkSMedia]

I've been learning Java in my CS degree for the last three years, I had no idea records were a thing!!! So cool!

[leeamraa]

Quality, effective, efficient and much appreciated content.

Could you do a video on Consumer, Predicate, and Supplier? I mostly understand what they do, but not when to use them.

[pclclau]

At 5:00 you mention that Java generates a default, no-arg constructor *even if* you don't create other constructors. That isn't quite true, Java creates a no-arg constructor *only if* you don't create other constructors. This is why your fields get red underlines as soon as you manually create the no-arg constructor, because there would be a way to have final fields that aren't initialized as soon as the object is created. Before you manually created the no-arg constructor this wasn't a problem, because Java wouldn't generate one since you already had the previous one created.

The way of teaching is totally different.. thank you so much for the deep knowledge that you are sharing... kindly make tutorial on stream api in future

[argonwheatbelly]

Guitars 🎸, drums 🥁, and programming. 💻 Yep! You're definitely part of my tribe. Excellent video! Keep it up.

[rohitsharma-xtqe]

This is something new for me and this video has full of information, every single sec is worth it, Thanks John 😊

[chenchi]

I like the style of teaching, very clear examples and no bs, earned a sub...

[pradiptaspointofview]

Explained quite clearly with detailed examples. Excellent tutorial! This is what I needed to start working with Records in Java.

[nishantsirwani]

Very elaborate and to the point explanation, thank you!

[ArjunKumar-zukl]

Just wow John, you are awesome. Clear voice. Thank you so much...

[ShreyasS-bnlm]

Hey man, this tutorial on Java Records is good! You broke it down so clearly, the basic parts makes sense. Thanks a lot for this awesome content!
