Sir you made me understand collections concept in very little time. Thanks a lot. I am now comfortable enough to use collections in the DSA questions and other harder topics in Java. Waiting for more videos in Java series. thanks once again.
Put in a lot of effort for this. I hope this would be helpful. Very few resources would cover topics in such depth. Also , next video on Multithreading. Just need your support to continue making this , as making tutorials are the hardest thing to do🙂
Thnx
Plz make some project based mullti threading viedo..
Thanks waiting for multithreading video
Waiting for multi threaded videos
@@DeepakLalchandaniProfile its already uploaded
I have never seen such outstanding and premium content on the collection framework ever. thanks bro now i say that i master collection and credit goes to you...!!
Need to switch job , but need to understand spring boot perfectly. Pls make on that also...a perfect playlist.
Pure gold, putting in extra effort to cover all practical aspects of collections much appreciated
Fantastic course! So glad to have found your channel. Looking forward to checking out more videos from you. Your comprehensive coverage of these concepts is very valuable!!!
My respect for you has increased multifold after watching Collections, MultiThreading, Lambda videos. Thank you so much, Riddhi. A lot of efforts goes into making these videos. Making them for free is next level thing.
Would love if you can cover stream separately.
Best explanation ever. Thanks a lot Riddhi for sharing it. It cleared a lot of doubts of mine and I m now very much confident to implement any collection.
Great content bro. Finally someone is teaching industry oriented stuff.
More to come!
This is the best video I found on collections and thanks for putting lot of efforts, to make us understand the collections in deeper way.
Please make a video on core java in interview aspect
Everything under a single hood really concise and clear content for perfect beginner
Hey thanks, especially for the starting part "iterator and iterable" it gave real clarity.
Glad
Awesome video as always. Just wanted to make a request please make a course on entire java development if possible along with core and java too. There aren’t any complete good courses available online as of now. I wouldn’t mind at all paying money to learn from you. Pls consider this request
Amazing video..super resourceful and we'll communicated!! Thank you Riddhi
What a masterpiece it is Hats off to you sir, this is my some how 11-12 video on collection framework but the level of depth you gave me is much much much satisfactory.Please make more videos on what ever topic you want on java because i actually enjoyed this alot
watching the first video on your channel and watched and understood the 3 Hrs video in a single go, on the internet no one has explained Java collection in this easy manner while including all the smaller points, Thanks for the video 🙂.
Great Explanation, Thanks again !!!
In iterator example, why do we need to have OurGenericList inside the inner class since we can use the outer class's variable items?
Instead of index < list.size cant we use index < items.length ?
Thanks for the video, maybe we will be needing from scratch implementations of these Collection classes...
Thanks a lot for this detailed video. I have learnt a lot and I appreciate the great effort put into this video to teach a lot of people. More success. Thanks a lot!
Crystal Clear Explanation.
Don't check further comments
Just Watch this premium Content
Thanks for making this.. waiting for the future java videos
Thanks for the in depth explanation of collections. Super insightful.
Really appreciated the effort... thanks a lot!!!
TQSM, I'm eagerly Looking forward for your generics video ❤
Switching from C++ to Java after seeing the number of openings for Java. Really very helpful.
How did you do that like I mean I am programming in C++ but also overwhelmed by the openings in JAVA, how to do that???
Thanks Ridhhi, as usual this one too has been a great video :) Cheers
Very helpful man!!!!! I recently joined Zoho and I was a mean stack dev. You made Java Collections very easy for me
very good content to starts with collection and java interviews. even good for experienced persons
Very well explained, thanks for sharing quality stuff, can you share the notes related to this entire video if available please? As well as share some resources based on Wrappper class, boxing,unboxing,Comparator,Comparable interfaces,toString methods, if possible. Hoping to see some tutorials on OOPS in java from you. Do we go for Comparable interface only in case of custom classes where we need comparison strategy whereas we go for Comparator interface when we want to change existing order of comparison?
wow
Very very helpful one...Thanks a lot for this good content video.
Just started with it. Planning to finish up by tomorrow.
Thanks man best collections explain ever
Thanks Riddhi , for such a wonderful video and eagerly waiting for your next video on MultiThreading and lambda.
Thanks
Beautiful video man. Would love more and more such quality videos on core java , design patterns
+1
Thanks for these videos, Please make videos on java 8 interview coding question which u have faced in interviews and commonly asked coding questions. Thanks
Thanks for this video. Very helpful.
Thanks a ton man!!!!
Riddhi i don't know what else we can expect from you . simply you are awesome man but small suggestion from my side if u can plz extend the course duration on further videoes u have great stuff it's hard for us to grasp the same in short time 😅 give minimum of 20mins for any topic and maximum of 2days.still I'm ready to watch ur videoes 😅gud luck man
This is what I was looking for!, thanks bro!
Glad I could help!
Nicely explained.
It would be great if you can consider covering java 8+ concepts like streams and lambda functions.
In the pipeline

@@rite2riddhi Thanks Bhai
Saved your video on Java. Learning Kotlin at the moment for Android, hopefully by the end of this year I can learn Java for Android, or maybe early next year. Thanks, Riddhi for the tutorial you created here.
Thanks william
great brother thank you for the this osm video. I can understand your efforts. Can you make such a videos in hindi as well with simple language just real time scenario. apko bahot acchi tarikese explain krna ata hai
Thanks Alot 👏🙏🏻 Sir Your Explanation is Awesome... BTW I like You're HairStyle 🔥
Haha , Thank you
greate video of collection framework :)
Great Sir. Great content.
Still dont find the video on generics that you promised.
great video🔥, very helful
One of the best video I ever had on Java unbeatable content.Thanks a lot Riddhi. Keep it up.I really do appreciate your effort.
#G.O.A.T Content🤫🤫🤫👍🙌
Thank you
Unique Content , Loved it❤
Thank you for this tutorial , Sir please cover Generics , thank you so much in advance
Finally i found the best of the best
Would love a video on Generics and other advance topics
Very Good Explanation
It's a very informative video. Please make videos for custom implementation for all collection classes?
Please make a video on generics too.
Love from PK.❤
The time to traverse the LinkedHashMap is proportional to the size as it maintains the order on insertion in the form of linked list and to get the value as per the matching key(hashCode() of the key) it has to traverse linked list linearly one by on which makes it O(n)[n->size of the linked List] complexity.Here the size is the no.of entries in the map not the the capacity to hold the max no.of elements
Correct
Thank you so much😊
This video is great. Please make a video on Java Generics.
great video Riddhi da!
Quality Content :)
Thanks alot brother ❤❤❤🙏
Hey you are so damn good teacher i understand all things
You are a God!
Excellent tutorial. Thank you so much..
In Iterable and Iterator interfaces, we don't need to pass "this" to the inner iterator class. Correct? It can access items from the outer class.
kindly cover generics ..... this is a great video
NICE EXPLANT...
Awesome work bhai, Will surely refresh my knowledge over this. One quick Question.. Stream Classes are so important in java, There are many classes and its tough to remember which class does what... any advice how could i have a firm and a strong command in these classes?
Wait for my video😛
@@rite2riddhi haha sure !
Bro great video . need more Java videos in the d future p
More to come!
Excellent video bro! Thanks a lot ❤ A small correction @ 1:00:30, Queue is First In First Out.
Great video
in Iterable concept, private is not working with class ourGenericListIterator as it is showing error and we need to make get() set() method to access the private variable items and size. why it was not giving error at ur end
Hey collenction frame work , threading wala vid is really good
Can you teach Java from beginning as for c++ there are many like striver , love babbar but Java no one jisne dhangse pdhaya ho
need a video on generics, please !
Thanks so much
great video
👏👏👏👏👏good tutorial..... thanks
😊
Good explanation please make videos on springboot
Nice Content
Cool✨💯
Please make a detailed video on Generics.
am facing error while creating my generic list according tonyour syntax compiler saying unchecked or unsafe operations pls help me
completed full video best video on RUclips one feedback please make slides in dark template
Haha thanks. Multithreading se , itz all dark mode
Thank you sir
1:00:26 CORRECTION: Queue actually implements FIFO and not LIFO. THANK YOU FOR THESE VIDEOS!!
Thank you.
Hi,
Can you please make video for spring boot and mjcroservices also?
On the point video please give some practice questions on this and please a video on java generics
Will make video on interview questions
You have a nice base of subscribers so improve your voice quality it will be the main source of contribution to increase your followers by providing quality audio and video representation however the content is good.
Thank you
why is it a best practice to code against an interface rather than to assign the implementation class' object to its own reference ?
wow great lecture...Riddhi can u pls make such videos for OOPS concepts in JAVA ??
Sure
Really appreciate the time and effort you have taken to explain every small thing. This video is a goldmine. You are helping a lot of people. You are awesome :)
Thanks sairam. Means a lot
Keep this series going
I will
Hey @Riddhi ,
Please suggest me,
Should I go for full stack web developer course or complete Java developer(basic to advanced, collection frame work, spring boot and other Java technology) for long term use and demand in jobs as a fresher.
Depends on what you want to do.
Hey @SAIF ROCKS can u give me the link for the above 2 courses you have mentioned
so far best on youtube :o
