This course teaches learners (industry professionals and students) the fundamental concepts of concurrent programming in the context of Java 8. Concurrent programming enables developers to efficiently and correctly mediate the use of shared resources in parallel programs. By the end of this course, you will learn how to use basic concurrency constructs in Java such as threads, locks, critical sections, atomic variables, isolation, actors, optimistic concurrency and concurrent collections, as well as their theoretical foundations (e.g., progress guarantees, deadlock, livelock, starvation, linearizability). Why take this course? • It is important for you to be aware of the theoretical foundations of concurrency to avoid common but subtle programming errors. • Java 8 has modernized many of the concurrency constructs since the early days of threads and locks. • During the course, you will have online access to the instructor and mentors to get individualized answers to your questions posted on the forums. • Each of the four modules in the course includes an assigned mini-project that will provide you with the necessary hands-on experience to use the concepts learned in the course on your own, after the course ends. The desired learning outcomes of this course are as follows: • Concurrency theory: progress guarantees, deadlock, livelock, starvation, linearizability • Use of threads and structured/unstructured locks in Java • Atomic variables and isolation • Optimistic concurrency and concurrent collections in Java (e.g., concurrent queues, concurrent hashmaps) • Actor model in Java Mastery of these concepts will enable you to immediately apply them in the context of concurrent Java programs, and will also help you master other concurrent programming system that you may encounter in the future (e.g., POSIX threads, .NET threads)....

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.

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

The feedback will be similar to the first course, parallel programming in java, such that the course contents are good. The lecturer can explain the theory very well. But the homework is just repeating of the demo video. I hope we can have the opportunity to practice the actual thread creation, joining, etc. instead of using the API call.

some suggestions: *the assignment is too easy.*

perhaps make more mini projects with different situations to solve:

parallelize simple program (more!!) / identify and fix deadlock / livelock / improve performance for bad implementation)

thanks for your great effort in offering this course! GREAT JOB!

Generally, provided material is very usefull in modern programming experience.

Something I would change in the course program are instructions to use custom PCDP library. This hardly can be used in real-life projects in future. Some original Java constructions is a better choice for me.

Good refresher on concurrency from my OS class. The concurrent minimum spanning tree was interesting, but the assignment for it has a pretty bad grading system. Lectures are clear, except the linearizability part.

Actors could use a bit more time and i would add like small coding exercises in the middle may be ? Also, grading could be a bit ore lenient with speed up. I had to submit multiple times with very minor changes.

Course content is well-structured and covers basic topics of concurrent programming.

However, code quality and tests for exercises could be better. Usually to pass an assignment you have to send it many times.

Very good, but I'd like more practical examples and walk-troughs. If you don't get it the in the only example or the demo, then you're left on your own to Google for more examples and a deeper understanding.

Este curso depende del curso de Paralelismo, por esta razón se debe tomar los cursos en orden. Debería tener mas ejemplos de código para un mejor feedback de la teoría.

A lot of my time has been wasted due to a very poor explanation of actors. All it takes is "Actors have their own threads and that is how they are concurrent.

The course overall is good, but the autograder of assignment can be improved so that the students will not get frustrated to their answer for such long time

It was a really interesting course where the things were presented in a very simplified manner in which I could learn the topics in a short span of time.

content with just naming and simple theories of terms, is oversimplified. Actually Concurrent Java is harder and can be taught much more deeply!!

The course was niece. It could have made of use of a programming language from scrath rather than depending on the pre-built library.

Lo consiglio a tutti, Vorrei soltanto che gli argomenti fossero affrontati più approfonditamente dal punto di vista teorico

Good course, with relevant basics of concurrency, even if I expected deeper and detailed contents.

This course is great!... But... it could be better if code explanations are giving in the videos.

It's a good introductory course. The programming assignment are indeed too simple though...

Excelent course, just some mixups with the concurrent API used in the assignment for Week3

A good primer to concurrent programming. Week 3 and Week 4 assignments are well-designed.

Needs more assignments and would benefit from prescribing optional real world projects.

It was a great course introducing the learner about various aspects of Concurrency .

i learn new way to solve java concurrent programming questions.thanks to Coursera.
