Thanks a lot for all your sessions. So easy, clear and useful information for job.
You made it so easy sir thank you very much outstanding explanation....
Very Informative video ever I have seen over linked listed. Thank you very much for enhancing my knowledge
Hello Durga, I appreciate you for sharing such a nice presentation, I went through all presentation.
Also I liked your style of presentation very much, you should retain the same style that keeps people not getting board.
Good of few things which i liked apart from the very good content you presented are
"Arre linked list what is your second element" was really an awesome (telgu) strokes here and there is very nice :)
Keep up good work and thanks brother.
you deserve 1 crore views
Excellent teaching. Thank you very much sir.
Oye, can u pls remove last element 😂haha totally loved it.
You are more than a god to java
Thanks for this awesome session
I think even camera man can become java developer ! :P
True
Thank you Sir
Awesome. Just nailed it
Very detailed.. Nice work ..And very helpful

Thanks alot sir. I appreciate the crisp and clear way you teach. No bakwas only useful things :) But I wish you had good english speaking skill. Anyways you are awesome :)
Nitin Kandwal he is teaching java not English literature.
How is linkedlist faster than arraylist when it comes to adding/removing an element in the middle? Let's say we want to insert a element at 50th index in linkedlist so to do that we first need to get to the 50th element one-by-one from the head, then add that element there, so where the efficiency? I guess when we compare adding/removing an element in the middle wrt AL & LL then the LL would score over the AL only because in AL shifting of the elements are required which seem to be a expensive operation. I would appreciate if someone can clarify on this.
Shift operations are more expensive
Please upload lectures on map also :) Second Half :P
Nice
please make some tutorials on jdbc
nice job by durga

sir plz upload queues part in collection
Sir , For adding elements at particular index in between must also be required to find out index of previous node then how come insertion operation is faster in LinkedList? for Ex. If I want to insert an element at 100th index then then this operation will also get impacted as before inserting a search for previous index is required which is a slow operation in LinkedList
Avatar Girase Linked list does not support random access, Random access here means, that you cannot directly access any element in a linked list similar to an array. In linked list you have to traverse each element (link) starting from the head and then you can access that element.l.get(n);This method also works the same way in the background. It traverse from the head and then retrieves the nth element
Coming to adding an element in the middle in ArrayList a whole new ArrayList needs to be created and multiple shift operations need to be performed and hence insertion/deletion in the middle will take much more time as compared to insertion of objects in ArrayList as no shift operations are required.Hope I answered your question.
Bharath but if we want to add something at 20th position then can linkedlist directly access 20th element or it will come to it one by one accessing each element?
In last LinkedList demo program l1.remove Last(); not written in the image

Sir i have 1 doubt is there no pointer support then how cand node point to the next node or previous node in LinkedList

cool accent.
sir , i have a doubt (please help me its confusing)
You said insertion takes less time in doubly linked list than retrieval but even when we have to insert an element in linked list at a particular position we have to start from head node, and count till position where we want to insert the element . So won't it have O(n) time complexity just like retrieval where also we have to start from head and iterate till particular position . Sir below is the algorithm for insertion in linked list , wont it take same time as retrieval which is O(n).
(note:I have not considered boundary cases here)
Node n=new Node(int data);
Node temp=head;
int count=0;
while(count

Plz contact our online team durgasoftonlinetraining@gmail.com or call us on this number +918885252627,7207212427/28
Yes, finding element means similar to searching it's o(n). but after insertion there is no shifting of elements like ArrayList. I don't know fully I thought like this.if it's wrong pls correct it.if u find any answer.
sir if u dont mind tell me retrieval defination plz
Hello Sir,
Could you please tell what is the difference between these two methods
add(0, "M") and addFirst("M")
As both of these methods doing the same work
add(0, "M") is I think the method of List interface, It is already there for the all Collection classes
Then what is the purpose of addFirst() method
Hello Bharghav.
Plz contact our online team durgasoftonlinetraining@gmail.com or call us on this number +918885252627, 7207212427/28
to add new element as the Head node i think, because when u add an element to ArrayList by default, it adds at the ed of the List.
If people say show me god I will show them the playlist
I have one doubt please clear that..Underlying data structure or underline date structure
Hello Friend.
Plz contact our online team durgasoftonlinetraining@gmail.com or call us on this number +918885252627, 7207212427/28
Sir, you have not discussed about the default size of linked-list.
Either we have to fix it or it can be dynamically changed
Please refer 16:10 from video, he explained there
Sir what is the Difference between collection framework and data structure .. why I am asking because Data structure concepts are mostly used in Collection Framework(may I think) please clear me the doubt sir...

sir,i want short term definition of LinkedList (i mean one line defination)
Awesome tutorials!!!!
PS: what's 'keep subating?'
+Mayur Kulkarni He means sub-heading
Oh wow that was deep :D
+Mayur Kulkarni Hahah..
He means keep summarizing.
+Heena Giri right heena what is ur mobile no
Adding element to middle is easy but how it's maintain index.
Because when we add element is 2nd position then remaining all element index need to change

Durga sir, whenever I use import java.util.*; it underline with yello mark . what should I do in such case?
Hello Ashish.
Plz contact our online team durgasoftonlinetraining@gmail.com or call us on this number +918885252627, 7207212427/28
simply means you did not use this package in your program, try one variable int count=0; and dont use it ,it will show you yellow mark.
what is the implementation of double linked list?
what if i store the address of each node in a array? the best data structure ever??Rookie here
Why this error is coming for me?

I have a query:
In Java there are no pointers, then how are next and previous node values handled?
Rohit Raikar references are used in place of pointers
remove "lust" ?
