I bet no one will google about Map, hashmap, and Entry after watching this video. Thank you for these amazing explanations and clarification, you are the Best SIR.God bless you
Very detailed video. brilliant tutorial on Map and HashMap. Only minor change i found out Entry Interface is sub set of Map interface. but in this tutorial it is mentioned as part of HashMap.
You are the best teacher.I am learning a lot through your videos.The first thing I am going to do after getting job is joining your channel. Thankyou for all these efforts for us.You deserve more subscribers.
Sir apki teaching techniques bhut achi hai mera 11 sal ka gap ho gya hai mca complete hote hi meri marriage ho gyi to me job ni kr payi isliye 11 sal bad mene apki video dekhkr sb kuch fir se sikh liya thanku sir🙏 ab shayad me job le sku it company me
I was worried to switch automation QA after having 14 years of functional QA. After going through your videos I think the best trainer you are in this world ..concepts interview Q & A everything you make so easy for me now ...Thank you so much sir..
Thanks for the tutorial? What’s is the best time to use Queue in automation and any tutorial on other classes that implement queue interface? Can you help us with converting Map to Map ?
Vedios are good,with detailed explanation. I would suggest to make wordings corrections,like in map you said new record is repalced with old record when you add new entry with duplicate key and different value.But actually it is old record is replaced with new record.
Just for my note: Hashmap is a class implementing Map interface. Hashmap implements Hashtable data structure. Entry interface is nested interface of Map interface.
Somewhere in between, 26-27 min, you said, HashMap is an Interface and Entry is sub-interface of HashMap. But isn't HashMap a class ? It is not an Interface and Entry is an interface that implements Map interface not HashMap. Could you please clarify for your students ?
@@abhay6276 One interface can extend another interface... But can not implement another... I think the class will be... Abstractmap.simpleentry, Abstractmap.simpleimmutableentry... And the interface will be... Interface map.entry....
yes that is the same question from my side Hashmap is interface is this correct and also entry is subset i did not get this point . Can you please explain little bit confusing here . Thanks in Advance
Hi sir, At last step using iterator method While(itr.hasNext()) { //i simply wrote like this System.out.println(itr.next()); } And then o/p is 101=john 102=david 103=scott 104=mary 105=tye So we can write like this no instead of writing map.entry all those

Your is explanation is superb.i want to ask you on duplication of the key ......................i try to duplicate the key and i try to run the ouput will be updating the key . why???
Hello Hope you see this comment ..... I am new to automation testing and just have switched from development to Automation Testing..... I know my question might be stupid and baseless but as a fresher in Automation/SDET I always wonder about this as I want to continue growing in the automation field and which is what motivated me to switch from development....But this one question always keeps me down and bothers me a lot in my path....I dont know why but my developer friends always tell me "You should be in development as the focus more now is shifting towards developer doing everything rather than having a separate qa automation sdet ....Developer also does some automation in some companies .....This is what my friends tell me and which bothers me a lot .....I igonre them But as a human having little experience in automation what is your take on this? I know this might be a stupid question that only a fresher can think of but my friends always warn me that future is more towards the developer doing everything and no separate tester will be required.....I 100 percent dont want this to be true as I love automation but one time I want to listen to your thoughts on this and clear my stupid doubt(even if this question pisses you off) You are my teacher so I ask you as a student the reality of this (I have gone anonymous because I am ashamed by my own question ) If you read this please reply ......🙏🏻
Your friends could be right because with the rise of Agile methodology and the extensive skills a technical QA possesses, there would be little difference between QA and Dev down the line. It is trending that way. With that said, QA industry is not disappearing abruptly. In fact, IT job market is so volatile that today's dev skills won't be sufficient with the rise of AI. So, don't panic. Whichever industry you like, grow in it.
I bet no one will google about Map, hashmap, and Entry after watching this video.

I really found this very helpful tutorial to get your basics clear on HashMap. Thank you for creating this content.
Welcome
This is the best explanation for Map and HashMap. Very detailed and concise. Thanks a lot. Subscribed.
Glad it was helpful!
to the point explaination no lagging only clear explaination very much thank u sir
Being a C++ programmer, i watched this video just before my java coding round. Feeling quite confident.
Yr way of teaching is awesome

Thank you sir for collections framework classes vedio series
Very useful video on collections work, thank you sir
Welcome
Very well explained Sir
Thank you Sir!!
Most welcome
thank you so much for this wonderful treasure sir!🙏
Welcome
Just for my note:
Hashmap is a class implementing Map interface.
Hashmap implements Hashtable data structure.
Entry interface is nested interface of Map interface.
very nice tutorial sir
Thanks
thank you sir,,,,i understand clearly.
Welcome
Somewhere in between, 26-27 min, you said, HashMap is an Interface and Entry is sub-interface of HashMap. But isn't HashMap a class ? It is not an Interface and Entry is an interface that implements Map interface not HashMap. Could you please clarify for your students ?
TQ I'm confused at this time TQ for clearification
Please clear me in easy way...still i am confused...
Exactly
Map(interface)>>>HashTable(class)
>>>HashMap(class)
Map(interface)>>>Entry(interface)
@@subhajitchakraborty8724 ok....means entery is a subset of map interface...m i right...?
What is implement.. ? Please reply sir
@@abhay6276
One interface can extend another interface...
But can not implement another...
I think the class will be...
Abstractmap.simpleentry,
Abstractmap.simpleimmutableentry...
And the interface will be...
Interface map.entry....
Ur explanation is superb 👌. Can u pls cover full core java and data structures.
Neatly Explained.
Awesome video !! Thank you very much
Glad you liked it!
thank you sir very good explanation

Extraordinary explanation. 🙏
Thanks
Well explained 👍
Thank you
Amazing explanation
Thanks
Best explanation
Glad you think so!
At 26:38 you said under Hasmap Interface entry Interface exists , earlier you said Hashmap is a class, please clarify that point.
yes that is the same question from my side Hashmap is interface is this correct and also entry is subset i did not get this point . Can you please explain little bit confusing here .
Thanks in Advance
Entry interface is nested interface of map interface not hashmap. Hashmap is class
Hi sir,
At last step using iterator method
While(itr.hasNext())
{
//i simply wrote like this
System.out.println(itr.next());
}
And then o/p is
101=john
102=david
103=scott
104=mary
105=tye
So we can write like this no instead of writing map.entry all those
Thank you sir...
Welcome
Sir, can we add single key & multiple values in hashmap?
Yes. but you can store multiple values as a single object.
*Difference between Print result of:*
m & m.entrySet ?? (same)
Difference in bracket.
Thank you sir!
You are welcome!
I wish you could also cover hashcode and equals method explanation
27:00
I think Entry SubInterface of Map (I(
Thank you sir

Thanks Pavan
Welcome
Nice sir
Thanks
thanks a million sir.
Welcome
Do you have any tutorials on Java Lambdas or Streams?
yes. plz check playlists
you must have also added the concept of comparable and comparator interfaces in this collections tutorial.
Sir , I have a doubt. How Entry interface can be child of HashMap, Since HashMap is a class right ? Entry is child interface of Map right ?
Now can we get some coding challenges and how to approach them with collections @SDET-QA
Sir what about TreeSet?TreeSet is also a class which implements set interface right?
Sir kya possible hoga esa gap ki wajah se koi problem to ni hogi
Please tell us the exact return type of entrySet. Google is confusing me...
Your content is superb and personally I've learnt so much from your videos.
Just an advice.
For 15 mins topic you take 1 hour.
If you want to increase your subscribers and views please make short videos.
but you told hashmap a class and again saying entry is child interface to hashmap interface?
thank you
Welcome
HashMap is not interface it is class
Entry is not sub interface of Hashmap
Sub interface of Map
Map.Entry
Your is explanation is superb.i want to ask you on duplication of the key ......................i try to duplicate the key and i try to run the ouput will be updating the key . why???
hi Sir, Very nice video, you are doing a very good job, Thank you.
How can we update the value for a specific key ?
sir is there a way to create a list of maps or Map with collection of maps?
Pavan sir, any idea on Qmetry automation framework?
Thank you sir
Sir HashMap is a class but you told in starting of Entry(I) like
Interface HashMap{
Interface Entry {
}
}
It's like bit confusing me .
hello sir, can I extract all the keys value, like[101,102,103,104], using (for) loop, not using (for each) loop, Please replay sir🙏

Dude if you don't want to work like a nerd stop to do that. Don't think over and over about that and just change your line that's it.
This question was asked 2 years ago and I would say the demand for automation testers are more still. Keep learning 😊
why is it written hashmap interface. it is a class right??
How to give dynamic value in hashmap in java
Where your learn this so much of stuff?
