Hello guys, if you want to learn Data Structures and Algorithms in 2024 and looking for best resources then you have come to the right place. In the past, I have shared a lot of useful resources like best data structure 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 the best online courses to learn Data Structure and Algorithms in Java.

Even though the topics are completely independent of 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 is 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 Data Structures and Algorithms Bootcamp.

Data Structures and Algorithms Bootcamp

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 have excellent teaching skill, 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 provides value for both your time and money.

10 Best Java Data Structure and Algorithms Courses, Classes, Tutorials, and Certifications

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

This is my go-to course to any Java programmers 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 structure 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.

3. Graph Theory Algorithms

This is another fantastic course on Algorithms by William Fiset, the instructor of the previous class. This course actually 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 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 it can represent relations like how two persons are related. You may not know, but many social networking websites like Facebook, Twitter uses graph algorithms to find your friends, colleagues, and other people you may know.

4. Object-Oriented Java Programming: Data Structures and Beyond Specialization

This is one of the best course specializations on Data Structure and Algorithms for Java Programmers. If 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.

10 Grokking Algorithms

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 the visual diagram, which makes learning more engaging and helps to understand key concepts better.

Here is the linked to buying this book — Grokking Algorithms

Overall, simply, the best Algorithms book for any beginner and highly recommend 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.
