Top 10 Courses to Learn Data Structure and Algorithms in Java - Free and Best

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 for 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.

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 knowledgable 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 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.

2. Easy to Advanced Data Structures

This is an excellent course to learn Data Structure and Algorithms on Udemy. The author is a former Google Software Engineer and he has a strong knowledge of data structure and algorithms. The course is also full of visual diagrams and useful animations, which are crucial to understanding how data structure and algorithms work.

More than 23000 students have already benefitted from this free course, and if you want to kick-start your Data Structure journey, there is no better free course than this one.

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, router 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. Data Structures and Algorithms Bootcamp

This is a perfect course for anyone preparing for coding interviews and want to brush-up their data structure and algorithms skills. In this course, you will not only learn about fundamental data structure 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.

5. Data Structure part 1 and 2

This is an excellent beginner-level course to learn data structure and algorithms. In this course, you will not only learn the core data structures and algorithms used in everyday applications but also understand trade-offs involved with choosing each data structure, along with traversal, retrieval, and update algorithms.

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.

You need a Pluralsight membership to access this course, which costs around $29/month or $299/year, but if you want to explore, you can also check it for free by signing up for their 10-day free trial.

6. Algorithms, Part I

This is one of the most popular online course on Data Structures and Algorithms, not just in Coursera but also on other learning portals. If you have read Algorithms 4th Edition, one of the better books on Data Structures for Java developers, then you will be surprised to know that this course is based upon that book, and instructors are also the author of the books.

This is a two-part course where the first part covers elementary data structures, sorting, and searching algorithms. The course is free, and 100% online, which means you can learn from your own schedule.

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.

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.

That's all about some of the best courses to learn Data Structures and Algorithms in Java. As I have said, the list contains both free and paid courses and you can choose the one you like. Whatever course you choose, be honest with that and do all the exercises they suggest.

If you want, you can practice more by solving standard Data Structure and Algorithms problems from interviews as well. You can see this list of 100+ Data Structure and Algorithms problems to start with.

  1. I am a computer science student. Earlier i was looking for a course that can teach me programming from scratch. I am going to share my experience about pepcoding that has done an exemplary work.Pepcoding is providing its content free of cost. Since I found their content very much effective and it has helped me in learning programming from the very beginning. Therefore, I am sharing their post with you.
    “We at pepcoding have recently made our level 1 data structures course, free for all.
