Watching this in 2024. Amazing information on GC fundamentals. Thank you! 👍👍

Update: 80lpa in 2022 for 2/3+yoe Original (2019-20): I think for a 3 year experienced software engineer, video until 34:02 is more than enough for an interview. 1. Heap divisions and GC working 2. Types of GC and their commands Present a story revolved on the below topics on the day of interview and ask for 35LPA Rs. Get competing offers and negotiate to 45LPA Rs / 300K USD / 85K Euro / 100K Pound / 150K SGD (these are the maxed out TC ranges, only RSU/4yr included, per geography I have collected from TeamBlind, levelsfyi, reddit and LC ). Other important Java topics: 1. Oops 2. String, String Pool, Immutability, Builder, Buffer 3. Collections: When to use what, equals, hashcode, comparable, comparator, internal implementation of Arraylist and Hashmap 4. Generics: Why generics, type erasure, generic class and method 5. Thread: Race condition, synchronize/lock, threads block/Deadlock Less important Java topics: 1. Exceptions 2. Serialization 3. Reflection 4. Unit test 5. Design patterns: Atleast singleton Spring: 1. Why spring, spring boot 2. IOC and Dependency injection 3. AOP 4. Design and Implement an api: controller, service, repository, entity, model, mapper, validation, security, datasource config in yml, liquibase, unit test case DBMS: 1. JOIN 2. Normalization 3.

Watched this in 2024, both this one as well as JVM Architecture video. I can say that I will be willing to pay for this quality of content. Please keep on uploading more informative videos

great tutor! you should do more videos

You're awesome! Actually, it's most detailed and cleanest explanation I've found so far on YT. Thank you!

This is probably one of the best videos on Internet explaining Java GC. I am so happy I found it. Thank you Ranjith for sharing.

Such a high quality introduction, thank you kindly!

Honestly, I didn't realize at the beginning that it's going to be awesome at middle and toward the end. Great video. Thanks for sharing your knowledge.

dude, you're an awesome teacher. The last video I tried to watch on this was impossible to follow. this is awesome.

Great tutorial about GC! I must say one of the best starting from basics till advance nitty gritty of GC.

Outstanding ! Thank you, Sir.

appreciate how you broke down the different types of GC algorithms. This is a must-watch for anyone looking to improve their understanding of memory management in Java.

This is exactly what I was looking for! Very well explained. Great job! :)

This is only i saw in youtube very well explained and cover the topic in very nice way to understand , Thanks for sharing and look forward for more topics.

Well prepared tutorial. Thanks for sharing knowledge.

Superb ...it's one of the best tutorials I have seen. Thanks a lot 🙏

One of the best video on GC. I hope you make more such videos

Very nice explanation with clear animations !! Thanks for sharing this and appreciate all your efforts in creating the animations !! :)

Excellent explanation of GC I’ve ever seen. Thank you so much!

Wonderful explaination. Really enjoyed and cleared all the internal concepts in Garbage collection. Thank you very much for this informative video👍.

Excellant explaination.. never ever before understood this concept so clearly. U must do lot of videos .

This is the best tutorial on GC that I have watched so far on KZfaq !

Awesome....even a person having no programming background can easily understand by watching this video. Thanks a lot!

Excellent vedio.. thanks you Ranjith. we are looking for more videos on Java and advanced java from you. thank you for your extreme effort to make these videos

Your knowledge and understanding is incredible. I would be interested as to the path you took to arrive at where you are as a Jedi programmer. If you know of any great books and material that would guide the rest of us in a similar path, I would happily follow. I have watched several of your videos and I don't think I've seen a better teacher online. I absolutely love your videos and will definitely keep watching master Yoda.

Very useful so much of informative video

Best tutorial on GC... please do more such videos

Thank you for enlightening on GC...!!! Great video..!!

Great explanation with succinct example. Thank you...Waiting for more tutorials from you.

awesome video man, i really like your references to actual java code. makes it really clear to me. thanks for the video

Thanks a lot for GC theory. This is much needed. Thanks again.

Best JVM memory management video! Thanks!

Very informative video sir...thank you

Very nice presentation on GC. This explains every corner of Garbage collection in java. Thanks Ranjith...

Summary: Steps in garbage collection: mark, sweep, compact Division of heap into Young (Survivor spave from, Survivor space to) and Old generations Minor garbage collector runs mark and sweep in young generation Major garbage collector runs mark, sweep and compact across the heap Types of GC: Serial (single thread - stops app during MSC), Concurrent (runs CS along with application) and Parallel (multithread - stops app during MSC)

Well-explained, sir. With graphical representation, you have made the concept crystal clear.

Great explanation! I understand Java GC so much more now.

Very comprehensive explanation of GC tuning. Thanks to share your knowledge with us.

Probably the best video on garbage collector

This is some kickass explanation. Please bring some more tutorials on different topics

Very nice video. All fundamentals of gc explained simply and beautifully ! Thank you !

Excellent video. I never learnt about GCs. I really enjoyed this tutorial. This was really helpful. Thanks :)

Quality video . Thanks for sharing this video

Amazing videos! I am in the process of binge watching all of them. You should consider becoming a tutor in LinkedIn Learning. You have a terrific approach and really talented.

crisp and clean explanation of GC

This is what I am waiting for long time. even lay man can understand. Thank you Ranjith.

Very well organized and explained. It clears the basics of GC

Btw Parallel GC is the default garbage collector in java 7 and 8 and not G1. G1 is becoming the default gc in java 9. Cheers

What a comprehensive explanation on garbage collection. Thank you.

As a java developer too many years ,this video is very useful for me, Cool......

That was a wonderful explanation Ranjith. Though some of the information was something i knew earlier, you explained it much better with all other options available. I especially loved the explanation of GC Algos, I couldn't comprehend the differences between them completely even though i went through multiple sources, but your explanation was crisp and concise. The visualizations were rock solid too...thanks for video :)

Very impressive content. thanks for sharing... Keep up the good work

very well explained waiting for more videos thanks for sharing with us
