Hello guys, In the past, I have shared a lot of useful resources like books and tutorials to learn Data Structure and Algorithms for both beginners and experienced programmers. I have also shared a lot of Data Structure and Algorithmic interview questions like this and their solutions in Java. Still, I have got continuously queries about excellent online courses to learn Data Structure and Algorithms in Java. Even though the topics are completely independent with the programming language, Java developer definitely likes the online courses which teach Data Structure and Algorithms in Java, and that's why my recent post about best algorithms courses, which includes algorithms courses from JavaScript and Python didn't impress my readers.
Some of them also requested free algorithms courses instead of paid ones while others are happy with the excellent course regardless of whether it's free or paid. To fulfill my promise, I did some more research and bring with me a new list of Data Structure and Algorithms courses in Java, which contains both free and paid courses.
Some of the courses like Deep Dive into Java are common from my previous list, obviously because it is one of the best paths to learn algorithms and data structure in Java. But, the list also contains some new courses like the Data Structures and Algorithms Bootcamp from Udemy.
This time, I have focused more on finding courses which teaches essential data structure in a fun and exciting way, rather than picking the courses which cover a large number of data structure and algorithms but didn't do justice with that.
Another reason I have included more than a few courses is that not everybody connects to the instructor I like. Everybody is different, and they should only join the course where they can connect to the instructor, I mean they like the voice, the style of explanation, and the content itself.
If you join a course where the instructor is both knowledgeable and enthusiastic and also has excellent teaching skills, you obviously learn more and retain that knowledge for a long time. That's the goal of this article to come up with online training courses and certifications, which provide value for both your time and money.
It also covers Big O notation, which is quite important to explain to you a solution during a coding interview. This is a paid course but doesn't worry about the price of $200, you can get it very cheap on various Udemy sales at just $10, almost 90% saving.
Most of the data structure and algorithm questions are followed by calculating their time and space complexity, hence mastering BigO is really important for any Software developer and you can use this course to learn how to calculate that.

10 Best Data Structure and Algorithms Courses, Classes, and Tutorials in 2024
Without wasting any more of your time, here is my list of some of the best online training courses to learn Data Structure and Algorithms for Java Programmers. I have taken care to choose the course where examples are given in Java, except the last one, which is a book with Python examples, Sorry I couldn't resist telling you guys about the Grokking Algorithm book, which I admire a lot.1. Data Structures and Algorithms: Deep Dive Using Java [Best Udemy Course]
This is my go-to course for any Java programmer who wants to learn data structure and algorithms. This is a comprehensive course, and it not only covers basic data structures like an array, linked list, binary search tree, stack, queue, hash table, but also advanced data structures like heap and algorithms like counting sort, radix sort, and other constant time sorting algorithms.It also covers Big O notation, which is quite important to explain to you a solution during a coding interview. This is a paid course but doesn't worry about the price of $200, you can get it very cheap on various Udemy sales at just $10, almost 90% saving.

2. Object-Oriented Java Programming: Data Structures and Beyond Specialization [Coursera]
This is one of the best course specializations on Data Structure and Algorithms for Java Programmers. As you know, a Coursera specialization is a combination of related courses to build skills and also provides a certificate once you complete all courses and do the required project.There are 5 Courses in this specialization that will teach you data structure and how to master your software engineering interviews.
Here is the list of courses included in this specialization:
1. Object-Oriented Programming in Java
2. Data Structure and Performance
3. Advanced-Data Structures in Java
4. Mastering the Software Engineering Interview

And, if you find Coursera courses useful, then I also suggest you join Coursera Plus, a subscription plan from Coursera which gives you unlimited access to their most popular courses, specialization, professional certificate, and guided projects for just $300.
3. Graph Theory Algorithms [Udemy Online Course]
This is another fantastic course on Algorithms by William Fiset, the instructor of the previous class. This course complements his last course because it covers advanced Data Structure like Graph, which is often ignored by programmers.If you know, the graph can represent anything related to each other like cities connected with roads, routers connected with cables, and even Facebook users connected with friends.
The course covers essential Graph algorithms like Breadth-first search algorithms, depth-first search algorithms, Dijkstra's algorithms, the shortest/longest path on an acyclic graph, Travelling salesman Problems (TSP), and many more.
The goal of this course is to teach you to apply graph theory in a real-world situation. Since the graph can be used for many common real-world problems, knowing graph theory helps to visualize the problem better.
The most significant advantage of graph algorithms is that they can represent relations like how two persons are related. You may not know, but many social networking websites like Facebook, and Twitter uses graph algorithms to find your friends, colleagues, and other people you may know.
4. Data Structures and Algorithms Bootcamp [Udemy Course]
This is a perfect course for anyone preparing for coding interviews and who wants to brush up on their data structure and algorithms skills. Since most of the coding interview focuses on Data Structures, Algorithms and System Design, it make sense to brush up these 3 topics really well before your next coding interview.In this course, you will not only learn about fundamental data structures like an array, linked list, hash table, binary tree, heaps, and sorting algorithms but also learn about the whole coding interview process and how to solve those commonly asked coding interview questions.
This is a two-part course where the first part covers linked lists, stacks, queues, binary trees, and hash tables, and the second part includes data sorting, string searching, sets, AVL trees, and concurrency issues.

10. Grokking Algorithms [Book]
This is not an online course but a book that I admire a lot. It's one of the best books on Data Structure and Algorithms, which I have read in recent times. It's not a comprehensive book like CLRS or Introduction to Algorithms by Thomas H. Cormen, but it's much more comfortable and enjoyable to read than that.
It doesn't cover all the data structures and algorithms, but whatever it covers, it covers them well. It's full of visual diagrams, which makes learning more engaging and helps to understand key concepts better.
Overall, simply, the best Algorithms book for any beginner, and highly recommend it to anyone who wants to learn Algorithms. There is only one thing which you may not like about it is that the examples are in Python than Java, but the theory is superb and for that alone it deserves mention here.
