this is what I've been looking for and I'm glad you've made a video on it! You have one of the best teaching style
Hands down by far the best tutorial on Java Collections Framework. Crisply explained :) Thanks Anuj
What a wonderful description of such complicated topic. You surely did such a commendable job with this. Much appreciated for such wonderful content. Loved it.
My 6 months of coding knowledge and understanding in 1 hr 15 minutes. To those people who had trouble understanding hashcode, equals, comparator, comparable: just keep trying, you will understand it. Comparator is really important because sometimes to solve a Q, you need to sort the input data in a particular way, which can be easily done with the help of comparator.
The way covered this whole framework, really appreciate your effort. Otherwise I would drop collection before start. Brief and to the point video now I can dive deeper into data structure.
Thanks a lot for this! As an experienced Java professional I can say that this is going to be immensely helpful to lot of us.
Thanks, Man. Just amazing. I was looking for a short video to go through the collections and this popped up. Keep up the good work
This is so simple & amazing! I always get confused in collections but I think now i know the clear difference. Thanks alot.
I have to give Interview tomorrow for Java I need a short video on java collection aur lo aa gyaa ❤️❤️❤️

"Yes, It was Helpful" The way you divide the tutorials into subsections helped me to complete this lecture in a span of 4 days.
One of the best Video On Collection, in very sort period of time he has covered every things. You'll never find such content on KZread (you may get only till list, set but not covered the whole Collection). Hats of You Anuj Bhaiya.......!!!!!!!!!!!!!!!!!! Note: I'm here post watching 2-3 tutorials on collection. and I having every things clear now.
This is helping me a lot, preparing for interviews with this and your DSA Series. Thank you again!
This was exactly what I like. Direct to the point, no testing patience by over repeating sentences or pauses or slow. Superb! Thanks.
DSA was such a nightmare for me since months.After watching this single video, I got such immense confidence.I can't express my gratitude to you bhaiya.I am going to complete whole DSA one playlist.

How was your current DSA level? how many problems are solved? Contests ? JOB status? please tell
Yes definitely it was very helpful. Understanding the need and use of collections with such ease. Awesome video if you want to have a quick refresher :)
Great video explaining all the required essential Java collections. Thanks :) Good for revision purpose
This was great! My suggestion for next video would be for advanced collection concepts. A few examples 1) Advanced functions like map.compute() 2) How collections are internally implemented 3) Thread safe collections like concurrent map and synchronized set and their internal workings.

I am so glad you finally made this video i was waiting for that . Thankyou so much ❣️
Bro, You are a gem. Hats off to you. You have saved 120 pages of text of reading Collection framework. Thanks a lot and keep up the Good Work :) .
YES, collections framework just in 1hours mind-blowing. Thank you, Anuj Bhaiya
This is the exact thing i was searching for weeks....
Video content and quality were superb. The best thing was you skipped the part where you typed everything and directly showed the methods and output. Super useful video for a quick recap of all these topics. 👌🏻
Awesome video, really enjoyed it. I always used to get confused in Collections, you taught it very well.
Short, crisp and to the point. Thumbs up for the work.
This is actually a really amazing video. Summarises everything perfectly period. Recommend everyone to watch this in order to build a strong base. I was able to crack Morgan, Goldman, PayPay, slice and Arcesium.

Also a note to everyone, please watch this before you start leetcoding. Jaise khaana banane se pehle kaunse bartan use karne hain pata hona chhaie, waise hi coding ke liye java collections framework ka accha idea ho toh coding main maza aata hai. It helps to figure out what to use and how efficiently.

You explained things so easily. Thank you.
Honestly, this is best video on collections on internet. i watched harry's playlist, videos on udemy, but still they are unable to clear concepts , you make all them clear...... thanks for it. want more videos like this....
Thanks for again explaining the hashCode() and equals() method in HashSet. Got so much clarity. Yes, it was very very helpful.
This was something I was looking for for a couple of weeks but those contents are a bit scary! Thank you so much Anuj Bhaiya! ⚡💖💖💖. Tons of Thank you for this!
Thank you, your teaching style is amazing :).
ABSOLUTELY SIMPLE , TO THE POINT , EXPLAINED IN EXTREMELY UNDERSTANDABLE LANGAUGE . AMAZING!!!!!!!!!!!!!!!!!!!
Very Nice content Sir i was worried regarding this collection framework of java but after going through this video, all my doubts and theoretical knowledge got fullfilled
Many many thanks sir 🙏🙏🙏🙏... it's very important, useful video for us.. whatever videos you make for us all are really very useful for us.. again lots of love and respect for you Sir🙏🙏🙏...
I literally forgets to like, but at the time 53:29 the moment you told like, I did that without wasting a single second, I liked and subscribed instantly. Thanks.
Tonight I have learnt many new things such as Stack, Queue, Deque etc. This video is really helpful for me. Thank to you. ♥️♥️♥️
Bhai sach me kaafi helpful tha. I signed in to my youtube account just to like and comment. Well deserved praise.
after seeing the title - oh hell yeah , this is exactly what i need
"Yes, It was Helpful" Thank You.
So much helpful... it resolves my confusions which I got while learning from different platforms. Thank you
Nicely explained. Appreciate the efforts to make it as simple as possible.
Watched this video today, and I must say that I was here after learning about Collection frameworks. Still, I found this video useful because of the things you mentioned about time complexity and having unique custom objects for Set collections. Also, you made Comparator, and Comparable look so easy. Thanks for this tutorial, I'm having an interview within a few days and I hope I can crack it.

Yes, this was the best tutorial on the Collection framework I have ever seen.
way of explanation is so easy clear and understandable ...i started to see your video from today and i feel that i can finish java within 5days...thank you so much sir ..you r great
bhaiya, 2 din me pura complete kar liya maja aa gaya 3 videos dekhi ekdam java dimak me baith gaya , diploma ke 2nd year me kiya tha, thoda bhul gaya tha, apki videos short but very useful hoti hai, apki DSA playlist ko bhi follow karta hu, time bhi bachata hai or knowledge bhi milta hai 'YES, THE VIDEO WAS VERY HELPFUL" 💌❤
Please make a separate video for difference between these collections with time complexity, null values,duplicates,default sorting and include comparable vs comparator. BTW very good video indeed.
Something next level on youtube ! Kudos to your hardwork & teaching skills. Thanks for such amazing content.
All my concepts became crystal clear after watching this video, Great efforts Anuj bhiaya
You're a superb teacher, keep bringing this kind of knowledgeable stuff... Thanks a lot.
I was scared at first when I think abt collections, now I feel far better, Thanks bhaiyaa ❤❤

Hey awesome video... Can you make a video on serializable class and how these collection classes extend it. Basically how to use the classes in multithreading for thread safe implementation.
thanks for making this video, basics very well explained in just 1 hr.
best video on collections framework on youtube , very easy to understand
Bhaiya please make your DSA-One series, better than Apna College, content wise. Because their content is very vast and lots of different questions, but explanation is not good. You're the god of explaining things❤️❤️ Edit- hope you notice this comment anuj bhaiya. Ps- till now your content of Dsa-One is 🔥🔥❤️❤️

Defiantly Yes that's why I watched this video thill end. This video amazing. It gives me a base to clear all concept to start more practice with collection framework.
Explained the concepts of Collection framework in java in such a simple and concise manner. This is the best video out there for learning java collection framework. Really appreciate your hard work sir. 🙏
Kya sahi topic choose kiya hai sahi moment pe kdk bhai🔥
Sara Google ghumkar aayi to aap ke video me sara ka sara data mil gaya........ "Dhany ho aap". Very easily explain each topic and only necessary things is discussed in this video...thanks bhaiyya
Yaar Sharma jee . . . . bahut hi saral aur lagu video banaya apnae collection concepts ka . . . bahut bahut dhanyawaad . I am subscribing your channel I loved it thank so much
yes indeed it was helpful. Thanks for this video, really appreciable .
Just to update : There has been a change internal working of arrayList (Till java 6) newCapacity = (oldCapacity * 3/2)+1 = 16 (java 7 or later) newCapacity = oldCapacity + (oldCapacity >> 1) = 15 Default Capacity * Load Factor = Threshold (10* 0.75 = 7) The number of buckets will automatically get increased when the table has 7 elements in it. ArrayList which is 50% more than the old capacity
Waiting for explanation of real-time usage scenario for every collection. Hopefully didn't find such a thing. Please make a quick video to identify which collection we have to use in a situation.
Perfect video to learn Collection Framework. Good examples with coding practice. Good work 👍🏻
Covered all DSA in one hour just because of this legend. what an easy explanation.
please make a video on time line of different companies when they hire interns 👏👏👏👏👏
