How to implement Doubly Linked List in Java ? | Data Structures and Algorithms

Watch all my playlist here:

Want to land a software engineering job in the IT industry? This course - 'Visualizing Data Structures and Algorithms' is here to help. The course walks you through multiple Java algorithms, data structures problems, and their solutions with step by step visualizations, so that you are actually learning instead of blindly memorizing solutions.

The course covers in and outs of Data Structures and Algorithms in Java. Java is used as the programming language in the course. Students familiar with Javascript, Python, C#, C++, C, etc will also get to learn concepts without any difficulty. The implementation of various Algorithms and Data Structures have been demonstrated and implemented through animated slides. It covers many interview room questions on Algorithms and Data Structures. The questions and solutions are demonstrated by -

1. Animated slide. (To make visualization of algorithms faster)
2. Coding algorithm on IDE.

The course covers topics such as -
0. Algorithm Analysis
1. Arrays
2. Matrix
3. Singly Linked List
4. Doubly Linked List
5. Circular Singly Linked List
6. Stacks
7. Queues
8. Binary Tree
9. Binary Search Tree
10. Graphs
11. Priority Queues and Heaps
12. Recursion
13. Searching
14. Sorting
15. Strings
16. Trie Data Structure
17. Dynamic Programming
and many more ...

Best series for DS & Algo. I am also 10 yrs java exp guy. Was looking for DS & Algo free course over YouTube with java implementation and found this. Hats Off To You Man..Excellent Work. GOD BLESS YOU :)

Sir, your DSA using Java course is very understandable and I'm able to follow it thoroughly.
I've some doubts sir, why didn't we create a constructor for SLL in previous videos? And why didn't we create isEmpty() method in single linked list videos? Kindly please clear my doubts sir...

[KodieMalibu]

This was helpful and fast. Thank you very much and keep up the great work

[travenishere]

Very well done - you helped me a lot.
But is there a reason not to have data as a type of Object ?

[prova_prime]

you helped me to avoid the use of sentinel nodes

[amirbayat]

Thank you so much for this set of videos. It has helped me a lot in my journey. I was just thinking . . . should the Node inner class be static?

[doggyooo]

Sir, instead of using a parameterized constructor of the outer class to instantiate the ListNode type declared variables - 'head', 'tail', and the int type 'length', can't we instantiate them in the ListNode constructor itself? Like we did for Singly Linked List.

[kamaldeep]

Nice Video. Just wanted to call out that no need to initialize instance variables.

[KlanBr]

we also have the LinkedList in the java.util package, than implements the doublyLinkedList structures, right? i wonder if it is exist someone to the SinglyLinkedList too in the java.util package, or maybe another package?

[Snowmanver]

thank you for this tutorial! Subscribed!

[foodfairyshi]

Useful video. very well explained. Thank you!

[arjunpal]

All the file or class contains in one class...But if you try to make separate class for a particular task that will be more efficient and also be easy for our understand. Please avoid using inner class. Make separate class for separate task

[videoclips]

why class make private please explain sir

[hemanthvijay]

sir which version of JDK and eclipse you are using in Mac

[jayachandrann]

It's a very short video and won't use for an experienced person to refresh. You haven't provided how to add the node and iterate the node.

maybe u can put english subtitle in next video
