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

[@dineshahuja848]

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.

I really found this very helpful tutorial to get your basics clear on HashMap. Thank you for creating this content.

[@sdetpavan]

Welcome

[@jayasree2033]

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.

This is the best explanation for Map and HashMap. Very detailed and concise. Thanks a lot. Subscribed.

[@sdetpavan]

Glad it was helpful!

[@sanjiwanipole3666]

Explanation is superb and no unwanted talk in between the session...

[@Rocky-t4c]

to the point explaination no lagging only clear explaination very much thank u sir

[@pradeep492]

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.

[@sanghamitramishra6169]

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..

[@aswinsrikanth408]

Very well explained Sir
Thank you Sir!!

[@sdetpavan]

Most welcome

[@anupamr437]

Just for my note:
Hashmap is a class implementing Map interface.
Hashmap implements Hashtable data structure.
Entry interface is nested interface of Map interface.

[@peterbet6487]

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 ?

[@udaykumar-ur2ug]

TQ I'm confused at this time TQ for clearification

[@abhay6276]

Please clear me in easy way...still i am confused...

[@subhajitchakraborty8724]

Exactly
Map(interface)>>>HashTable(class)
>>>HashMap(class)
Map(interface)>>>Entry(interface)

[@abhay6276]

@@subhajitchakraborty8724 ok....means entery is a subset of map interface...m i right...?
What is implement.. ? Please reply sir

[@subhajitchakraborty8724]

@@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....

Thank you

[@myvoice4407]

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

[@dharmendramakineni]

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 ?

[@rajansethi6767]

At 26:38 you said under Hasmap Interface entry Interface exists , earlier you said Hashmap is a class, please clarify that point.

[@harindersinghgusain9372]

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

[@priyakrish7433]

Entry interface is nested interface of map interface not hashmap. Hashmap is class

Difference in bracket.

[@rajkumarm25]

Please tell us the exact return type of entrySet. Google is confusing me...

[@explorersbasichunt4117]

Sir, can we add single key & multiple values in hashmap?

[@sdetpavan]

Yes. but you can store multiple values as a single object.

[@yaswanth2332]

you must have also added the concept of comparable and comparator interfaces in this collections tutorial.

[@priyadarsinisahoo2544]

Sir HashMap is a class but you told in starting of Entry(I) like
Interface HashMap{
Interface Entry {
}
}
It's like bit confusing me .

HashMap is not interface it is class

Sub interface of Map
Map.Entry

but you told hashmap a class and again saying entry is child interface to hashmap interface?

sir is there a way to create a list of maps or Map with collection of maps?

[@omgfinishers7405]

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 ......🙏🏻

[@peterbet6487]

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.

[@NuanDaa]

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.

[@Forty3Stories]

This question was asked 2 years ago and I would say the demand for automation testers are more still. Keep learning 😊
