Linked List implementaion in Java without using Collection
We will use Eclipse IDE here
In this video we will see :
- What is Node
- Step by step explanation on how linked list works
- Operations of Linked list
- insert
- insertAfter
- insertAtIndex
- delete
- showList
- An example explaining LinkedList creation, insertion and show
Linked list is a linear collection of data elements, in which linear order is not given by their physical placement in memory.
Instead, each element points to the next.
It is a data structure consisting of a group of nodes which together represent a sequence.
Under the simplest form, each node is composed of data and a reference (in other words, a link) to the next node in the sequence.
This structure allows for efficient insertion or removal of elements from any position in the sequence during iteration.

My interviewer asked to implement Link List.
I watched this video before one day of interview date at night.
I implemented successfully in first attempt.
Now he asked me to sort it.
I tried but failed.
But he didn't rejected me.
Keep in mind learn Link List sorting also.
Thank You Telusko
Where did you interview ?
@@mathewa3531 Infosys power programmer
@@mysteriousloop1377 I'm curious, did you try to sort it? or did you just say that you couldn't without trying?
this is probably the best way someone on the internet has explained the topic.first give foundational concepts of the topic,second drawing it out and then showing the code implementations. i will recommend this playlist to the class i teach. thanks alot .
lol are you the guy who invented blockchain?
Is here anyone to explain me. i am a beginner in java. Can i complete data structure of java i mean this course before core java??
@@mayurmahajan22 Until you don't know how objects are getting created, how they have referred the basic syntax and all the basic stuff, that would be hard to learn, or you can work harder and can learn both of them together.
@@vivekdubey2270 Hello can you help me
I have question that what is Node next ;
@@right4you915 node next is the address which is pointing to the next node... Say you are a linked list you have tow hands, left hand you hare holding a cake, in second hand you are holding a piece of ppr which have the name of your frnd who is holding candles, then your frnd who is holding candles, is holding candles for sure and another piece of ppr which have the name of the frnd who's birthday this is...
So you are the head node, your right hand is node next, your scnd frnd is node, who's right hand is node next.
😌😌😌 Hope this explain the working of linked list.
this is for all the college professors out there, this is how you teach, this 20 mins video was more helpful than two 1:30 hr classes. This is the best way I have seen someone explaining linked lists to me
I had a four hour class about it. I learned much more from this video.
@Shay Treadwell Yes, I did. It was mostly a lot of different examples.
I'm kind of a Professor :P But I totally agree with you on this. This way of explaining... with code + examples... is a whole lot better and supposedly students could understand this faster.... BUT! It must also be coupled with the student wanting to learn this stuff :) Anyhow... this is a good tutorial for LL :) Good job!
Thats perfect, thank you indian guys, you always try to make everytjing clear in your tutorials
Sunnatjon Savrulloev 😂😂😂😂😂😂
Guys, I have made 4 general attempts to watch and understand this stuff. I didn't count endless flashbacks within the video itself for 10-20 seconds. The author is right - you might make several attempts, to get it all right. Gratitude to the author for such a great work!
To display the values, you can use
while(node!=null){
System.out.println(node.data);
node = node.next;
}
that way you don't need to use the second print statement.
Awesome videos, really helpful.
lol i know it
can I ask you how ?
how it is will know to compare the address with out I say "next"
Well I was about to write this amazing comment, actually this is put account that he was teaching and as well as programming, so he had to change the whole concept, that would lead chaos in learners mind, that is why after figuring whole error out, he chose easy way to solve it.
On the other hand the person who made the comment follow a great convention in coding that is to avoid as much as possible to simply not write same code statement again and again. Thanks for reading.
@@giveaway4002 Well, he sort of the used the same logic when he wrote, if(head == null).
or a do-while loop maybe ?
Absolutely amazing. The best explanation of a linked list I have ever seen hands down. The use of the whiteboard whilst running the debugger is genius!
Thank you so much for this - I have been following other tutorials online to learn more about data structures and algorithms, however this is the first one that really explained what was going on. Great work!
I like how you explain the classes to be used. Great Work!
wow! you made it so easy to understand. I've been trying to understand linkedlist creation for about a week now no avail, but just your one video make me grasp it all. thanks a lot
This is quite possibly the best elaboration to the linked list data structure I have even seen. Thank you Telusko.
This is the best explanation I have gotten for linked lists. I can finally finish my project! Thank you so much.
concise yet informative.Keep going man! Thank you very much.
Thank you!
Excellent work!
Really the best way of explaining this on the internet.
It helps a lot for me!
Keep it up!
Thank You so much Navin sir!! It was uploaded way long back but your tutorials are inseparable!!
This is the best tutorial for this topic. Thank you so much for helping me and I have watched countless tutorials on it but I just can't seem to grasp the concept clearly, but u helped me. Thank you so much for the explanation!! Have a great day!
Sir ,for traverse the node u can check condition as while(node!=null) for reducing the last line SOP(node.data).
Crct
Wow. Finally I understood. Clear and concise. Thank you!
Great explanation !!! I really wanna say I was not getting how to approach linkedlist but after watching telusko videos i got it ....
I also watched apni kaksha and some other channels but they are not explanaing well and here all my concept become clear.
Thank you sir ,!!!
after watching it many times, finally I got to understood Linked List, thank you :D
The best explanation ever for LinkedList..... I have seen so many videos of others but couldn’t understand anything...Thank you 🙏🏻
Only after watching ur video I got clear idea in list thnks a lot sir.. 👍
of all the videos, I think this one helped me understand linkedlist the best. Thank you so much my friend.
Amazing explanation sir i have watched many videos about how to implement linkedList in java but here i understood.
sir, you are amazing. i try yo understand this topic for about 3 weeks. now i understood thank you so much
Telusko I love your videos, you are talented in teaching, this is really a great blessing. You are great man
Thanks for the extremely detailed explanation! This video was very helpful to see how linked lists are traversed :)
Very clear and concise explanation, just what I was looking for...subscribed!!!
I believe that this is the best way to explain to a beginner about how to implement a linked list, it’s articulated well. Thank you sir!
this is an incredible video Navid! absolute legend
Very nice video. You explained it so well that I was able to print all the values of my linked list before you notice the small mistake you made in the code. Happy to discover Telusko.
Great video man, I implemented it by myself thnx to your video. Will watch the other parts too later on.
I understood the concept very well. Thank you sir for explaining in such a nice way.
wallah you are the bast one disc. the singly linked list i have ever seen in the youtube, even my doctor in the university, thank you brother
Hello Sir Navin Reddy garu, All of Your videos are awesome Sir, I'm thankful to you, we all are, actually.
And one thing is, while printing the elements, in while loop, instead of checking the condition while(node.next != null), it would be more meaningful to check the condition while(node !=null) so that, we can print the elements irrespective of the last node which is obviously null.
instead of
while(currentNode.next != null)
{
System.out.print(currentNode.data + " ");
currentNode= currentNode.next;
}
below looks more good:
while(currentNode!= null)
{
System.out.print(currentNode.data + " ");
currentNode= currentNode.next;
}
. Love You Sir...
I could not understand anything wat i have learnt back in my university for whole semester but this video is doing great, i just understood the whole damn concept within 20 minutes ...... thank you
Sir, you explain so well, thank you so much for your help, honestly!
Happy New Year
👍👍👍 not only explained the code properly step-by-step, but also explained it using debugger along with diagram. 💛💛
Best tutorial so far , i have encountered so many tutorial , and this is the best!
Thank you so much, i was tring to code ir but wastnt able to i have seen allmost al videos on liked lis as fa this is the best way to code linked list have have found thank you again.
Keep doing what you're doing... love your video! Thank you so much! You have no idea how much this helps me.
Good explanation.I watched this 4 times,finally I understood 100%
Thank you very much for this thorough walk-through. I understood the concept of Linked list but was stuck at implementing it and your video helped understand it very clearly. hands-on approach is always the best way to retain a concept. Although I was searching for implementation of LL in Javascript, I was able to write it on my own since I saw how it is done in Java.
this is probably the best way someone on the internet has explained gr8 job sir
It was a amazing experience to learn it... Thank u sir♥️
Wow! Respect, now it is soooo simple! :D
Thank you so much ! This is the best turorial to see how LinkedList has been implemented in Java.
Whole heartedly thank you 🎉.The final part debugging is the part where we fetch everything...
I really appreciate you doing this. Many thanks!
Absolutely fantastic!
now i understand how oop concept works in building a data structure thanks to u. Keep up the good work!
Wow!! amazing explanation :)
I like the way of teaching and coincidence as well👌
It's really helpful for me, so i wanna thank you for this😃
Its a relief that object oriented was invented, carrying reference to the pointers was always a difficult part in the school. Thanks for the brilliant explanation Sir.
Love the way u explain.. clears the concept
even after watching many videos i couldn't quite understand the concept. but your video was great. i can write up code without having to look at google again. Thanks a lot :)
navin sir you are just awesome...Thanks a lot sir for the ossssmm tutorial series.
iconoclastic lecture..sir..aapka tutorial se hi meri college study kat rahi hain..
thank u sir
Yes, very helpful. I couldn't have gotten through my assignments otherwise. thanks
Thank you(*5) so much was trying to solve it from 3 days.
The only one who taught me the data structure entirely and easily.
Thanks a lot ♥♥
Great video, had to watch twice but i have it now. Thank you.
best tutorial for Linklist!!, thanks so much
I watch this video morethan 3 times .finally I got it.Thank you very much
this is the best video explained Linked List .. thank you so much
you were right i had to watch it multiple times to understand it, but thank you for uploading this video
India numba wan
Thank you guys for all these tutorials. From Mathematics to Programming, ya'll are there to save the day.
I had been trying to find a good explanation of the implementation of a linked list for 3 hours. But At last, I found this video. Why didn't I see this video first? I can't tell how helpful is this video for me.
thank you for this video this is really helpful i am jot able to find a single video which will explain like this
Thanks for the debug part, it helped a lot
beautiful explanation!!! kudos....
This is really a awesome video to understand linked list ...Thanks ton for the video :)
The way you explain things is simply Awesome!
from Saudi , awesome explanation he got me to the root and basic where these next , and head are doing , on simple word their job are to locate the tail of node they are chasing the null so they can tell us if we have one node or more !
Great explanation
Step by step
Really nice work
Awesome bro...understood linked list ...was trying to understand it for 4 days
hey finally i understood. i watched 4 times to understand the code. as he told consumes takes time to understand
Thank you so much telusko
Sir thank you so much for clearing my all doubt's. This video is helpful for me.
Very simle and clear explanation.
Way better than my professor. Thank you so much for this
Thank you, I have learned a lot.
Certainly did understand more about linked lists after watching, thanks :)
Thanks for the video it is awesome and explain linkedlist in a perfect way.
THANK YOU SO MUCH FOR THIS , IT MADE ME CLEAR MY BASICS
Thank you so much bro... I saw lots of videos but ur the best...
Great Work!! Thanks a lot.
Sir, you explain so well, thank you so much for your help
18:00 - insted of printing last node manually we can replace while loop condition with (node != null),. It will print last node automatically.
oo wow....thanks bro....😊😊😊
Thank you very much, this was really helpful.
Dear Naveen ,
why did you stop this amazing, wonderful series if possible please give us full dsa course in one video like core java,spring,spring boot,rest,hibernate..... And much more......I am grateful for all that yoy provide....stay safe stay blessed, stay being alien
Thank you so much, sir...!! And I get an idea to implement a linked list program in java.
you are the best man, you have explained it much better than my teacher thank you
thanks this video made my 2 week for learning how to implement the LinkedList in to just 1 hour
thanks a lot !!!, well explained here and hope to see like this video in future as well.
you can use while(node!=null) in show function to print all the values( including the last node) as node is referencing the node itself , just checked by printing the value of node.
Hampe to he hi 9
awesome video
incredibly explicit explanation sir. thank you!
This teacher is very clear, I like his style and I can understand what he says, his accent is very pleasant and he has a good mic!..
I was searching this information in java but I didn't find it anywhere.. This is exactly what I was looking for !!
Nice simple &precise explanation!!!
That might be best way someone explain the concept .thank you
It is really helpful. Thank You Sir
