I have to give Interview tomorrow for Java I need a short video on java collection aur lo aa gyaa ❤️❤️❤️
same bhai muje v monday to interview dena h
bro just wanna ask u, ki yrr tumne video dekh li, ye wali ? if yes thn is it sufficient for interview ?
@@adintuition3041 bhai kis chz ka interview h ?
Plz tell me imp topics of basics n advance java
yess ... same here, i am revising my concepts before accenture interview
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.
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
Hands down by far the best tutorial on Java Collections Framework. Crisply explained :)
Thanks Anuj
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 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.
Jbo
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
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.
@@diptanshuagrawal5040 Exactly, He is the person behind my interest in coding... I never been in love with coding. But Anuj bhaiya teaching always make things easy.
Bhai insta I'd milegi guidance chahiye 🙂🙏
"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 the exact thing i was searching for weeks....
I was scared at first when I think abt collections, now I feel far better, Thanks bhaiyaa ❤❤
Same
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.
The teaching quality as well as video quality is great...

This was exactly what I like. Direct to the point, no testing patience by over repeating sentences or pauses or slow. Superb! Thanks.
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 RUclips (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.
Kya sahi topic choose kiya hai sahi moment pe kdk bhai🔥
Pls make video on JAVA8 features.specially on stream API,lambda expression,optional class and functional interfaces
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 :) .
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"
💌❤
Guys don't be panic while learning coding
Believe in 'Anuj leap of faith' ❤️
lol, exactly what i think, everytime i see Anuj's video, ever since I saw that recursion video. I believe in Anuj's leap of faiths supremacy 🙏
@@takeshiasahi5494 , what's Anuj leap of faith. I have only heard of Lord Shardul Supremacy
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.
Bhai sach me kaafi helpful tha. I signed in to my youtube account just to like and comment. Well deserved praise.
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.
Thank u 🙏🙏
The only video I want 🔥
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
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....
This is best tutorial for Collection , easy to understand and to the point , I am now a subscriber for this channel. Thanks Anuj
You're most welcome 😊
is it just me who plays any tutorial video at 2X speed or am I normal ?!

Short, crisp and to the point. Thumbs up for the work.
The way you explain the concepts is really good.thanks and love from Maharashtra ❤️
One of the best video
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 am not into java but this helped me to learn more about collections.
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
Thank you bhaiya for this video.
I am so glad you finally made this video i was waiting for that . Thankyou so much ❣️
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.
Tonight I have learnt many new things such as Stack, Queue, Deque etc.
This video is really helpful for me. Thank to you. ♥️♥️♥️
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 🔥🔥❤️❤️
Agree ayush
Yes
I have seen all comments against the apna college course,is it really that bad?
@@jeeveshkumar5030 Its very fast like airplane
Yes
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. 👌🏻
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
Great video bhaiya!
My java journey started with you 3 years ago and still you are one of the best teacher for java
Good video 👍👍👍
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
Ig, you can use both... Both are fine to use
ABSOLUTELY SIMPLE , TO THE POINT , EXPLAINED IN EXTREMELY UNDERSTANDABLE LANGAUGE . AMAZING!!!!!!!!!!!!!!!!!!!
I didn't understand Sets of custom classes in this video. Rest all is really well explained.
Yes, it was helpful
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.
hii, have you crakced your interview?
Thankyouu so much. I just started java this video just clear all my doubts.
I am done with this collection video without taking any break.
Best Bhai ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
You explained things so easily. Thank you.
Bhai in depth , bahut topics cover kiye hain, one of the best!
In short Time Bhaiya You Explained complete collection amazing video Thankyou.........
Thank you so much bhaiya. It will help us to rewise the concepts and learn more new concepts
Bhaiyee kaamaal kardiya 🔥

Eagerly waiting for this video 😍 anuj bhaiya cloud engineering ke upar full road map laao na
Loved it @Anuj. Can you please share the diagram in the description. It'd be great help.👍
Till now best video on RUclips for collection

@@GoluKumar-xb1vt Lmao 😂
BHAI...CDAC krlo... Perfectly Developers Ban Jayega...
Mechanical Wale bhi..CDAC krke..IT walo se jada Package Lete hai..!!!
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.
Anuj Bhai you really good person and explain everything is very good ..
You are great sir..
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.
Plz tell some unique android development projects to get off campus placement ... Btw love Ur videos bhaiya❤️❤️❤️
The best one !!
yes , it was very helpful.
it helped me to get cleared all my doubts regarding implementation and theory as well.
thankyou bhaiya.
Love u vai
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
Your video is great sir, it cleared my all doubts and fear how to learn collection
YES, IT WAS HELPFUL AND I LOVED IT
THANK YOU BHAIYA❤❤
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.
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 🙏🙏🙏🙏😉
Next three or 6 month coding ki practice + apply karo bs
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
This video is already a gem❣❣. No correction needed.
Please bring roadmap for Amazon, what are the topics to be covered n everything related to it 🙏🙏🙏🙏bhaiya
🔥🔥🔥🔥
Man you are awesome love your teaching skill 🙏🙏
best explanation for such an important part of java core in just 1 hour
