"When I started watching this video, I realized it was going to be very helpful, but I stopped myself from commenting at that point. Now that I've watched the entire video, I can say this video is literally amazing. Each and every method is explained clearly, including why there is a need for further upgrades, the use of each method, and the drawbacks of each one. Everything is well-explained. I have watched others youtube channel for collection but this is unbeateble.thank you vipul sir for your hard work 🙏

[@tinkumaji1945]

I was waiting for this video and here it is with a bang, a full fledged 8 hrs video on Collection Framework and Java 8 together. Hats off to you man! 🙌 ❤️

[@p...p]

To help beginners understand how Comparator works, you could draw an analogy with the Bubble Sort algorithm, particularly its swapping technique. For example, in Bubble Sort, elements are swapped based on comparisons. Similarly, in Comparator, a negative return value indicates that elements should be ordered (or 'swapped') accordingly. This can make the concept easier to grasp (just a suggestion ✌)

[@rachnashah-b5s]

Absolutely amazing! I truly appreciate everything about this video-its knowledge, presentation, and the motivational touch infused with humor. I was so captivated that I couldn't stop watching until the very end. I completed it in one continuous 10-hour sitting! A heartfelt thank you for your effort and invaluable suggestions.👏👏👏👏👏

[@sadarsisters]

Sir, could not stop myself from commenting after watching the entire series. Hats off for all the hard work that has gone in creating this series. It is absolutely amazing. And your funny statements in between made it feel like we are actually in class room enjoying live demonstration. Have never commented for any youtube video before. Thank you so much for creating this. Really really helpful if someone wants to understand in depth.

[@TheSkillGro]

Man na padeja , the way you teach is incomparable to any other KZbinrs or udemy instructors there. I have been watching online courses from a long time, but you are very unique. You have very good knowledge of the domain, you teach the things in a very cosy and funny way, that’s to in native language , which makes us easy to understand complex things. Feels like watching some very funny movie, don’t have to stress ourselves to learn something complex

[@rohandeshmukh-n4n]

Best lecture of all time for java collections framework , Great tutorial bhaiya :)

[@p...p]

I already have about 60 % knowledge of the Java Collection Framework , and I estimate it will take me a week or two ⌛ to complete this video and revisit a few sections for better understanding. Thanks for such an informative ✅, content-rich🤯 video! [currently I am at LinkedBlockingQueue ]
