thank u telusko sir
--regards from an alien

Lot's of thanks dear sir, Awesome videos, learning Java videos is a amazing. Perfect clarification - HashTable is synchronized and shouldn't it be a single thread instead of multiple threads.👍👍👍👍👍👍

The way of explanation is very crystal clear and understandable

One thing is wrong here,in hash map multiple threads will work at a time where as in hash table only single thread at a time( you did a mistake in comparison table )

You make it look so simple!!! Thank you very much sir.

in thumbnail ur dress very nice

sir pooja ka number band aa rha h...🙄

Love telusko since 2019

hardwork defines the sucess like the above example!!!!

Thank you so much for such partical and to the point explanation.
Thank you so much over again.

What is thread safe sir.

hi can you explain about HashSet

Is there any class called TreeHashMap? I think it is TreeMap only right?

hello aliens

I believe its not TreeHashMap. It is TreeMap

man please stop calling aliens please. It's annoying.

Legengs trying to call pooja archana

Thank you so much for this Navin

Ur from Telugu

Can anyone tell me, what is this sign <> ? Is it a paramerter or what?

Why can't we define HashMap like HashMap<>hmp=new HashMap<>() ?

Telusko in 2016, ...

navin sir ne apna contact number de diya h

Fantastic

Navin, you look so much better now, your English has improved and you explain better, Its amazing seeing how much you have improved

some people must love when sir calls us aliens, i guess

Is HashMap working single thread? HashMap is unsynchronized right!.. so it's used multithreaded only, but you mention hashmap works with a single thread in the hashmap and hashtable difference.. if it is right you mentioned, please explain.

Naveen, How will we fetch all key and its values using old for loop ? i am trying but not able to do it with normal for loop ? could u please help..

Thank you 👍

🙏 tq sir

Puja and Archana did not live happily ever after . . .

Thank you sir

Thx for the valuable information

Sir can I use "List" instead of "Set" ???

We can iterate directly also on entry set rather than saving first in Set.
for(Map.Entry<String, String> i : map.entrySet()) {
System.out.println(i.getKey()+" " + i.getValue());
}

why this statement is used:- "e.setValue(III)" ? What is the use of "III"?

it was direct in the point .. learned quickly thnx.

sir the first number is actual a number i called the number
remove that number

Is it possible to have a multiple attributes instead of just 1 key to 1 value like a CSV? eg

Name, age, weight
Bill, 18, 60

finally my map concept clear thankyou sir :)

Non Synchronised works with multiple threads and Synchronised works will single thread....I think

can you please tell me,why in hashtable ,no null key is allowed?

thank u da mota thala
