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.

I have to give Interview tomorrow for Java I need a short video on java collection aur lo aa gyaa ❤️❤️❤️

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.

Hands down by far the best tutorial on Java Collections Framework. Crisply explained :) Thanks Anuj

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.

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.

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.

"Yes, It was Helpful" The way you divide the tutorials into subsections helped me to complete this lecture in a span of 4 days.

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

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.

This was exactly what I like. Direct to the point, no testing patience by over repeating sentences or pauses or slow. Superb! Thanks.

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" 💌❤

The teaching quality as well as video quality is great...

after seeing the title - oh hell yeah , this is exactly what i need

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.

I was scared at first when I think abt collections, now I feel far better, Thanks bhaiyaa ❤❤

Pls make video on JAVA8 features.specially on stream API,lambda expression,optional class and functional interfaces

Kya sahi topic choose kiya hai sahi moment pe kdk bhai🔥

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 :) .

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 KZfaq (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 the exact thing i was searching for weeks....

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 🔥🔥❤️❤️

Hands down the most helpful video for me to challenge myself again on all the concepts and best in class revision, I feel your efforts in every minute of the teaching! Appreciation from USA 🙏🏻🇺🇸

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....

Guys don't be panic while learning coding Believe in 'Anuj leap of faith' ❤️

Thank u 🙏🙏

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.

This is best tutorial for Collection , easy to understand and to the point , I am now a subscriber for this channel. Thanks Anuj

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. 👌🏻

Please make more videos on Java. This is gold!

Bhai sach me kaafi helpful tha. I signed in to my youtube account just to like and comment. Well deserved praise.

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.

The only video I want 🔥

This is great⚡✔️

1:15:00 What is lambda?? Lambda Expressions were added in Java 8. A lambda expression is a short block of code which takes in parameters and returns a value. Lambda expressions are similar to methods, but they do not need a name and they can be implemented right in the body of a method. lamda expression can be single as well as multiple: single:parameter -> codeblock Multiple:(parameter1, parameter2) -> { code block }

Short, crisp and to the point. Thumbs up for the work.

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🙏🙏🙏...

Thank you bhaiya for this video.

Tonight I have learnt many new things such as Stack, Queue, Deque etc. This video is really helpful for me. Thank to you. ♥️♥️♥️

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

I am so glad you finally made this video i was waiting for that . Thankyou so much ❣️

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

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

I am done with this collection video without taking any break.

"Yes, It was Helpful" Thank You.

Thank you so much bhaiya. It will help us to rewise the concepts and learn more new concepts

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

ArrayList growth doesnt happen by adding [current_size/2] + 1 in the internal array. It is done by adding max(sizeOfElementsBeingAdded, current_size*2). Please see ensureCapacity() method of the ArrayList class. Thanks!

One of the best video

Yes, this was the best tutorial on the Collection framework I have ever seen.

ABSOLUTELY SIMPLE , TO THE POINT , EXPLAINED IN EXTREMELY UNDERSTANDABLE LANGAUGE . AMAZING!!!!!!!!!!!!!!!!!!!

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.

You explained things so easily. Thank you.

Thank you, your teaching style is 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

The way you explain the concepts is really good.thanks and love from Maharashtra ❤️

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!

please make a video on time line of different companies when they hire interns 👏👏👏👏👏

I am not into java but this helped me to learn more about collections.

"Set ek Chatur Bag hai"😂... you are awesom man👌. Helpful video

Good video 👍👍👍

Loved it @Anuj. Can you please share the diagram in the description. It'd be great help.👍

So much helpful... it resolves my confusions which I got while learning from different platforms. Thank you

I've to give interview Tommarow for java and i was really happy with this simple explanation Thanks A lot ❤

Bhaiyee kaamaal kardiya 🔥

what's the difference between PriorityQueue = new PriorityQueue(); vs Queue = new PriorityQueue(); what are the pros and cons of each i can see from diagram PriorityQueue is a class that implements the Queue interface so both syntax should be fine i guess but which one should i use

It was an excellent video, Anuj. I had lots of doubts in collections and I needed a complete video of all the collection features. Your video has cleared all my queries. Thank you

Awesome video, really enjoyed it. I always used to get confused in Collections, you taught it very well.

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.

Yes, it was helpful

Great video bhaiya! My java journey started with you 3 years ago and still you are one of the best teacher for java

"Yes, it is helpful", I am having an interview in two days and it really helped to grab the concept. ❤

Thankyou for the bonus of comparator , comparable 🔥

Best Bhai ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

As an interviewer I always ask which element in an PriorityQueue will always be a top irrespective of Language. Most candidate fail to answer this basic conceptual question. Ans: Amitabh Bachchan

Perfect video to learn java Collections framework, Anuj Bhaiyan Can you make video series of DSA using Java language like Coding block provide Java Crux Master Course, their content is 80+hrs, please make playlist of it, it will be very helpful to every 2nd year student to learn DSA implementation from a single platform. Thank you so much for your efforts to teach us.

Oh my god bhaiyya thank you for this

is it just me who plays any tutorial video at 2X speed or am I normal ?!

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 :)

the way you explain is excellent . you make everything very easy and understandable

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.

Plz tell some unique android development projects to get off campus placement ... Btw love Ur videos bhaiya❤️❤️❤️

I didn't understand Sets of custom classes in this video. Rest all is really well explained.

Best content for collection for sure. One thing I will like to add here is please do give coding examples based on objects . That will help even more

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.

Eagerly waiting for this video 😍 anuj bhaiya cloud engineering ke upar full road map laao na

This is helping me a lot, preparing for interviews with this and your DSA Series. Thank you again!

Thankyouu so much. I just started java this video just clear all my doubts.

Please make a JavaScript tutorial video for web development

Something next level on youtube ! Kudos to your hardwork & teaching skills. Thanks for such amazing content.

Nicely explained. Appreciate the efforts to make it as simple as possible.

In short Time Bhaiya You Explained complete collection amazing video Thankyou.........

Bhaiya ek aisa video banao jisme un students ki baat ho jinhone 3 saal maje me kaat diye hai aur ab placement lena chahte hai plz bhaiya 🙏🙏🙏🙏😉

Love u vai

Veryyy helpful video anuj bhaiya! I've been following your videos for java since i was in 12th.. now im in my 3rd year Msssst padhaate ho aap!!

awesome course all concept revised and also learn Time complexity within one hours and clear all doubt about comparable and comparator within last 5 minutes by Collections.sort() method use.

Bhaiya Kisne BTech 3rd year Tak kuchh nahin karata uske liye kya road map hona chahie

Please bring roadmap for Amazon, what are the topics to be covered n everything related to it 🙏🙏🙏🙏bhaiya

This is so simple & amazing! I always get confused in collections but I think now i know the clear difference. Thanks alot.

What exactly is the difference between these two lines? When to use first one and when to use the second one? ArrayList goods= new ArrayList(); & List goods =new ArrayList();
