Sorry! I had a minor surgery that I'm recovering from at the moment so I've been delayed. But don't worry, I haven't gone anywhere, so once I'm doing better I'll be back at it.

Woh, I did not make the connection to the show and the sample names. I was too focused on understanding the concepts. Good eye!

Hi John! I'm a student of systems engineering. I'm from Colombia and your videos are making me improve in this language. Thank you!

Love your courses. Needed a reminder about sets and you made it crystal clear 😊

It’s amazing having access to Java tutorials with the same quality and enthusiasm other YT channels give to the likes of Rust or the latest JavaScript framework. Thank you John!

even though i knew all about java sets, i still watched this video to appreciate how well you teach these concepts. keep it up youre doing good work for the java community 🙏

In my opinion, John is the best programming mentor on KZread platform! Thank you so much, John!

Man respect ++ , The clarity you gave was commendable !

Thank you for all of your videos! You break it down in such an easy way to understand. Can you do a video sometime on serialization with examples and when to use it?

As a senior dev, i must say, watching your videos is very relaxing. Thank you.

What i couldn't understand from 1 hour long lectures,this guy just taught me under 30 mins hatss offf

I had to learn Java for a new job last year and while many of the concepts like Hash Sets have one-to-one parallels in other languages I’ve used, I’ve yet to read up on how to implement them in Java. This tutorial easily saved me a couple of hours of textbook reading. Keep up the great content.

Awesome, concise and clear explanation. Thank you John. I even enjoy watching the topics I already know, because I just love your way of explaining them.

your videos are helping me understand my Java coursework at Uni! Thanks for all you do John!

John. Keep them coming. I’m from india. Haven’t seen anyone who speaks organised. Precised as you do. Love your work. Bless you ❤

Hey John! Your videos are helping me get through the most important internship of my life. THANK YOU. Humble Request: can you make a video covering serialization/deserialization?

Another high-quality video, John. It actually came at the perfect time for me. I was making a whole lot of spaghetti code with ArrayLists and for loops, but then I realized that I need to focus on learning data structures for a while. This very lesson just happened to be applicable to a project I'm working on right now. I'm messing with an API that gives me random cat facts, and I've been getting a lot of duplicates.

Don’t usually comment but great video , I learnt a lot and I can see the connection with data structures better. Thank you John!

Am really really satisfied with the terms you use and the implementation of the concepts in a simple and easy to understand format. Thank you, Thank you, Thank you

Love your videos, learned daily new topics, though the I am familiar with the topic, Presentation is crystal clear.

Thank you, John, your explanations are very straightforward and easy to understand. I like the way you explain in the end how we can use data structures in real-world problems.

Ran into these at work today, so this is a nice coincidence! Thanks for the great tutorial

Your explanation of Java makes it easier to understand. Thanks, John!

This is awesome. Your videos have helped me so much. Thanks for all of your work.

I swear you are the best John 👊🏾

I love your way of explaining these concpts! Thanks John!

Absolutely clear and awesome quality, John. I love the content

Thanks, this video was great, Very easy and clear explanation!

Thank you so much for the detailed explanation this is a gem 😍

Thanks John, great clear concise videos. Perfect for a newbie and quick refresher.

Thanks John, with you I improve my code and my English. Greetings from Argentina

Thanks John, it was quite helpful to remember the working principle an difference between these.

This was great. Can we get a video explaining interfaces vs classes and APIs?

Thank you John for make me understanding difference in using Set() and HashSet() i had this doubt for longer time. Time in the video: 3:12 to 4:21

Hi, John! Could you make a video explaining encapsulation? Your explanations make it so clear.

Thank you so much for this tutorial!

Your videos are really good and concise, gives me insight enough. Thanks.

Simply Perfect and Perfectly Simple to Understand! Thanks a Ton!

Love your videos. So clear 🤌✨

Very good vid. It covers all the good stuff in plain English. Thanks John.

Thanks for the video. I haven't really used Sets in the past. Looks like I have some refactoring to replace instances where I used a List just to keep track of unique entries.

Excellent video as always. Thank you John!

Hi John, I love the way you teach. I really appreciate your hard work and effort. It would be very helpful if you make a series on Dynamic Programming. You have that ability to make complex code easier. Thank you so much for your wonderful videos

Hi Dear Sir ! I'm associat java developer, and I love the way you delivered the topics, especially Hashset and HashMap because I was so confused on these before I watched your tutorials Thanks ❤

Thanks John, Your video is very helpful to me, please keep it up .

John, you're VERY cool at explaining complicated things in simple words. Thank you so much! Very cool!

One of the best tutorial | Complete and Clear with examples

Thanks for the great video! I really enjoyed and learned a lot from it. Just wanted to add one little thing about the difference between HashSet and TreeSet: Elements of a TreeSet need to implement either the Comparable interface or they need to come with a Comparator, since the TreeSet sorts them out whereas HashSet just places them based on HashCode. This is a very small difference, but it can be important sometimes.

This is amazing! Now that I thought about it more deeply the idea is genius. I am studying the course on data structures and an introduction to algorithms and now I am thinking that it is possible, as you described at minute 13:15, to reduce the running time of searching for duplicates in a certain list from O(n^2) to O(n) just by using a HashSet. Thank you so much John for opening this thought to me, I will keep thinking about it in the future.Keep making more videos like this, it helps a lot!🤗

Thank you john. Loved It. God bless you

You made it look easy. Thank you John

Great tutorial as always John! Can you consider doing suffix arrays? I still struggle understanding it 😅

John, thank you so much for the Java lessons. As someone who is not fluent in English, having to read the error-filled KZread captions and follow the lesson at the same time, I actually understand your explanation better than my own professor's. Sending a warm embrace from Brazil!

You are really one of the best. Thanks a lot

Thanks for your content. A worth watch.

Great and simple explanation! Thanks!

Hi John, your videos are extremely helpful for me as I have joined a software firm after a long career break with no prior experience in Java. Can you please do a video on Persistence since there are not many videos on this topic?

John you are the best java developer i know, thank you so much for share your knowledge.
