[@maheshdhanraj9899]

Hi Ranjith.. Good presentation. This video helped me to understand the String concepts.thanks a lot.

[@ravipunia59]

Fantastic explanation. Waiting eagerly for your concurrency , exception handling and multi-threading videos.

[@ranjithramachandran5928]

Ravi Punia thanks, planning videos in GC, concurrency etc in upcoming episodes, please stay tuned, subscribe to the channel- if you haven't already.

[@jhguygih]

Very good!!!!

[@rahulsaini8]

Nice explanation

[@benjaminalexander7043]

Fantastic Tutorials!!! Really Helpful! Thanks! Will you be doing more of these?

[@ThePriyeshchandra]

Hi Ranjith, Really nice tutorials. Would request you to upload videos on some advanced topics such as multithreading, database connectivity, and may be some tricky java interview questions. Thank you for the awesome work. Keep it up.

[@ManishTiwari22]

good job ranjith.

[@lalatkishorechoudhur]

Hi Ranjith sir,Excellent presentation.thank you..........

[@info2nagesh]

Thanks alot Ranjith. Your videos on java are awesome, not comparable to others.

[@ramashan23]

Your are Topics are really Insight full and very interesting , Getting addicted to more of you courses , Keep up the good work :-)

[@ranjithramachandran5928]

+ramanathan shankar Thanks for the kind words! pls subscribe, I try to release at least 1 video in 2 weeks.

[@prakashm6084]

your teaching was super amazing very clear and in depth ...do make some videos on tricky java interview questions like 1. FINDING WHITE SPACES IN A GIVEN SENTENCE 2.FINDING NO OF DUPLICATE WORDS IN A SENTENCE 3. AND SOME INTERSTING CONCEPTS USIGN ARRAYS..

[@postflic1829]

some latest thing i knew after video like scp in heap memory, memory leak better n good explanation

[@Radhakankanala]

Great work Ranjith, the videos are really helpful, please make videos on other concepts as well.

[@ranjithramachandran5928]

+Radha kankanala Thanks, please subscribe :)

[@sunainagandra2924]

can you please upload more videos...your videos are very usefull for beginners

[@erfelipe]

Thank you.

[@devanathannarasimhan1410]

amazing thanks Ranjit, if possible can you share the java collections videos?

[@TheSaravkumar]

Unlike other videos, you have some originality in explaining without misleading the actual reasons. Good work ! If password is stored in char[ ] array , heap dump will have that too, maybe the approach shortening the time, certainly better than storing it in String but still not ideal to store clear text in char array as well. Right ?

[@ashishagrawal7709]

Its Amazing, pls provide some videos on ExecutorServices

[@kumar22bms]

Hi Ranjith, Excellent presentation keep it up. Am waiting for ur next GC video,please also provide, How to handle externally GC in java. HashMap explanation is supb

[@ranjithramachandran5928]

Kumar Nagaraju Pls check out kzbin.info/www/bejne/i5_Ef4Sdr9xnsLs - let me know if there are questions

[@sandipbhaumik]

If you can describe about the flyweight design pattern which has been implemented for java.lang.String, that would be great.

[@ShujathHussain0]

Awesome work. if you ever make a course please share a link, i'd love to buy

[@ravikumarizaac]

Hi Ranjith..excellent presentation.. keep it up...one question is ... with 1.7 as string constant pool is moved from permgenspace to heap, will these string constants be garbage collectable? if so how the cache of the strings is maintained?

[@ranjithramachandran5928]

Ravi Kumar , Yes Java 7 & 8 uses heap for String pool. At the same time,code objects(Byte code/compiled code) will contain one or more references to the String objects that represent the literals.So as long as the code objects are reachable, the String objects will be too - and hence it will not be garbage collected until the class that refers them itself is GC'd. The data structure that stores the pool is a map. I am planning a video on GC very soon, please subscribe for updates if you haven't already.

[@LetsBeHuman]

24:@2 - man, from where did you get the info such that substring has memory leak till java 1.7

[@yaminimehta4575]

Great video!! Why have you stopped making more videos??

[@rakeshpramanik]

wow

[@user-mt2if1ht8n]

Gold!

[@kalidask2493]

superb explanation. Can you please add topics about concurrency , threads ,Security.

[@ranjithramachandran5928]

kalidas k Thanks! yes, I am planning to put those out. Meanwhile please subscribe/check out other videos in my channel.

[@vlsnsatyas]

A very nice video. In the multithreading concept, Can you please explain why wait and notify methods present in object class but not in thread class

[@LetsBeHuman]

man, why did you stopped making videos. Your videos are best.

[@wizardsraj1234]

Thanks for this video. I had a question, given strings are cached in string pool I am correct in saying that those strings will not be garbage collected? Some people mention that only string literals and strings which are interned are cached in string pool is that true. Say String sFirstName = objUser.getFirstName() will the value of sFirstName be cached or not ?

[@nagarjunkalivarapu7966]

nice explanation it's really very helpful for interviews and learning. do u have any site or blog if there please post the link here we can read . thank you

[@smilerelax5265]

liked ans subscribed

[@9939364566]

Hi Ranjith... Thanks for the explanation. I have a question though. While dealing with immutable Classes, If we create 2 objects out of the class with the same values will they also have same reference?

[@vinodbhadu4576]

Ranjith sir, you are awesome but why only few videos, please make videos on java 8.

[@johnwilson3918]

Thank you - for this. You mentioned how a String's hashCode is cached once it has been 'interned' - but you've not mentioned how a check is done for a String existing on the current string pool. Doesn't this involve calculating some hash code?

[@wmj010cn]

create,clearify what's been confusing!Would you cast some light on string encoding in java,such the getBytes[] method from String class

[@srinidhiii]

wow man

[@nagadeepcs86]

If you dont call the intern method, simply if you call the hashcode function for S1 ="Hello" and S3 = new String("Hello"), it will have the same hashcode value but '==' equal method returns false. Does it mean internally they are same ? and intern is used to just have the equality of the object?

[@kalyanraju37]

I have one question wrt using new String(). As new String creation will not create anything in String pool instead it creates new object outside string pool correct. Then what is exact use of it?

[@gaaliprabhakar8882]

(Very nice)*1000 and if you have time please make a video on class loaders topic. Thank you so much

[@ranjithramachandran5928]

Hope this will help kzbin.info/www/bejne/kHOtYahvgsZ-qq8 a little bit

[@gaaliprabhakar8882]

I have seen this tutorial before , but that not fully explanation about Class loader.
