Examples and projects are somewhat "sandbox" grade, without touching real problems of this field. Code and tests quality is poor in my opinion.

I would consider it as a overview of possible approaches, not a course. Assigments could be frustating because outcome is sometimes non-deterministic (I wasted few hours of my time because of this, it turned out that my solution was fine). Sometimes given examples are not following Java documentation in details. They could not work in corner cases. It should not be the case in the course made by professionals.

Compared to the other courses I took authors of this one did not put much effort in preparing good materials and exercises. Course can by challenging by means of standing frustration assigments could give you. And in my opinion not because it is hard to pass them and they are demanding. It is because they are not properly prepared.

I have mixed feeling about specializations. This topic can be hard. And course mentions most of the important topics in non-sequential computer computing essential to making working systems. But it does not give deep insight in many of them.

Very basic

This is the worst online course I ever had. Especially the programming assignment. You just need to change one line or add one line, which makes this course like a video tutorial. Definitely not for an intermediate level learner.

This was a good course and covered all the topics relevant to the course. I liked the Optimistic Concurrency in week 4 - that was an area I was not exposed to before

Course was very good. I some how was not in favor of using the custom lib. i would have prefer we learning how to write that code.

Like previous course, The content is heavy in theory but not much in practical.

The course is pretty good and lays down the basic theoretical knowledge about concurrency needed to begin developing expertise in this field. The quizzes and projects help you remember and understand the theoretical aspects while at the same time the projects also give you a glimpse of how the learned theory and aspects are applied in a more realistic coding setting rather than pseudo code.

Great course overall but the difficulty of the mini-projects is not evenly distributed. Some are extremely easy while others seems to be too hard. Also it would be better to be able to use some libraries other than the RICE PDCP library which does not seem to be used elsewhere. For someone with moderate Java experience, the course could be finished within a week.

Dr. Sarkar is a great teacher. The course includes different kinds of implementations of concurrent programming using Java. The Quizzes and the mini_projects were of great help when it comes to the reinforcement and they were selectively chosen for providing the implementation knowledge about the topic as well.

Really good and brief introduction to concurrent programming. Professor is superb at explaining the basic primitives of concurrent programming in a language agnostic way. Furthermore, I found programming assignments quite helpful as well in cementing the learned concepts.

"It takes a genius to make it simple.”

Prof. Sarkar has explained and illustrated some of the complex concurrency and parallelism concepts in very simple terms. Even an experienced concurrency java developer will have something to take away from these classes.

Thank you.

Great introduction to concurrent programming concepts. Well-paced. Instructor is clear and personable. The mini-projects feel a little too easy sometimes, but at that point it's up to me to dig deeper and learn more on the topics. I enjoyed this course very much.

Great course. With minimal effort you can learn about important concepts and see immediate results regarding the actual speedup you can achieve using concurrent programming.

Excellent way to refresh what I learned some years ago in Operator System. Also I won a small hands-on experience using locks, isolation and high level concurrency in Java.

Amazing course. Especially for those who want to really understand the foundations behind multithreading and concurrency in Java. As always, Professor Sarkar is brilliant!

Very well structured and presented course! Very useful material with good relevant examples! Thank you, Prof. Sarkar for this Concurrent Programming in Java course!

Awesome course, it nudges students in right directions, provides them with solid fundamentals and encourages them to deep dive more into topics. Thanks a lot!

The course is well organized with very clear instructions. It helps me to understand several fundamental concepts about concurrent programming.

Very good explanation of the concepts of locks, and how important data-structures example HashMap are optimized to improve performance

The most challenging part was to pass the miniproject_4. I made some changes in the condition to get the passing score. Thank you!

Short and easy to understand multi-threading with locks, object-based isolation, Actors, Atomic values and optimistic concurrency.

Hard course, we need more assignments, small chunks. Making assignments for courses like these is not trivial as well.

Very practical course, it gave me understanding details about concurrency I've never heard before.

Thanks Professor

Very good course on concurrency that can be applied to many other programming languages as well.

Great way to learn about concurrent programming. How it works, and how to use it within Java.
