I've been on a streak watching your tutorials for my interview prep, you are really helping a lot in quickly brushing up and also learning new concepts. More power to you...!!

[abhishekgowlikar]

Everyone need this whether fresher or experience, Good Work and Content.

[vivekkewalramani]

this video covered all the key questions asked in interview. Please create these interview questions video more oftenly.

[nandinimani]

Just completed watching 😊. Whoever reading the comments section, pls watch his interview question collections videos without having second thought. You will get many questions in interview for sure. Sharing this with my personal interview experience.

Basant sir, please start series on data structures and algorithm, its a humble request. Please

[rabindrapatra]

57:53 we are just seeing treemap linearly. but it is not the actual way. treemap entry looks like below: static final class Entry<K, V> implements Map.Entry<K, V> {
K key;
V value;
Entry<K, V> left;
Entry<K, V> right;
Entry<K, V> parent;
boolean color = BLACK;
} what is color black here, what does left, right, parent doing.

One of the best interview videos ever seen for Java.
Excellent job. Thank you.

[abhishekprasad]

Request you to bring interview QnA on Microservices Architecture as it is a must these days in interview, also the vidoes of your are very helpful...Thank you !!

[jagdishkamadi]

@Basant Sir, thank you for providing such an in-depth explanation in simple ways.

[namjitharavind]

Thanks for the video. Concurrent HahMap is not Synchronised. ConcurrentHashMap in Java is indeed thread-safe, but it achieves this without using traditional synchronization mechanisms like locks. Instead, it uses a different approach called "lock-striping" and "compare-and-swap" operations to allow concurrent access from multiple threads without blocking them unnecessarily.

hi basant, just adding one thing here, if we use java 8 then no need to write custom code for sorting, checking multiple values,
System.out.println("");
System.out.println("name and salary basis in java 8");
Collections.sort(list,
for (Employee e : list) {
System.out.println(e);
}

checking one value,
System.out.println("salary basis using stream");
->

Thank you for the amazing videos on collections! Could you please create some content on data structures and algorithms as well? If you already have videos on those topics, could you share the links? We all love your work—you’re the best! Your guidance would really help us understand these concepts better. Thank you! Again love your work!

[santoshkamat]

Great tutorial brother. But i believe, for normal hashmap lock will not be applied on whole collection. Lock will be applied on whole collection in synchronised hashmap . And as u rightly said segment wise locking in concurrent hashmap
Anyways you doing a great job with interview playlist in helping so many IT people get jobs during this boom😄

[mubeenkazi]

most beneficial video, all concepts cleared. Will surely recommend

[Kunalsumanblogs]

Thanks allot for clear explanation ..I have gone through your and Durgesh sir video's ...And I am very confident about comming interview...

[bhawnarastogi]

So far the best and crisp, as it's not just tells theory..it's with example. Great job 👍

[arunprasad]

Thanks Sir.. Very much helpful in preparation.. Concepts are quite clear and proven

[AnilKumar-dtsq]

Basant Sir, first of all, I have no words to thank you. You are really doing a great job by sharing this invaluable knowledge and experience with us. However, one small doubt - if Set uses Wrapper class like String, Integer it doesn't allow duplicates. Only for custom classes we need to override equals() & hashcode().

[abhijitprusty]

It would nice help if you could make some video related to DSA which are mostly asked during the interview for all kind of technical postions in Java.

[RussianCyclop]

Great tutorial on Collections Framework interview questions, very informative, thank you!
