Thank you very much for the good introduction to a new language. Assignments are fascinating and thought out to the smallest details. I'm really looking forward to continuing the course with more advanced topics, like coroutines.

Awesome course packed with content and very well designed exercises! It was a pleasure to complete it! Thanks a lot to Svetlana and Andrey for this perfect intro to Kotlin for Java developers. Can't wait for the followup courses!

Great explanation of the core topics of Kotlin and the difference with Java explained by two great Kotlin's contributors.  Very good assignments. I would like to see more advanced topics and the next courses :)Thank you all!

Good comprehensible videos with lots of interesting exercises to keep watchers engaged. The weekly assignments are appropriately challenging. Would definitely recommend for Java veterans who are interested in a new language.

This is a very informative course which provides very elaborated understanding of Kotlin language as well as the exercises test the algorithm/logical understanding. Thank you for providing the good contents at one place.

Really helpful and in depth course about Kotlin. Brilliant explanation of Kotlin concepts against Java and why the design decisions were made. I feel I've read a book in a very fun way. Kudos to both the Instructors. :)

Very good course. Useful and compsed by interesting videos that help the developer to understand and doing practise with this new programming language. I advice you this course, if you want to start writing Kotlin code!

Very good course for Java Developers with lots of examples, easy explanations and interesting assignments. After finishing the course, I feel like I have a good knowledge of Kotlin and can use it in future projects.

I enjoyed the course. The learning videos have covered the topics very well. The most interesting parts are the in-video problems.

I liked everything in this video and learned a lot. Many thanks to Svetlana Isakova.

Helped me learn basics easily and the course is segreated quite neatly for proper understanding.

Assignments were the best part of thid course, a bit lengthy but were great to learn the fundamentals to the point.

Very good content here. I was already familiar with some aspects of the language, but there was a lot to learn. I enjoyed the assignments, quite challenging and very well thought. Can't wait for the next course..

Thanks very much, Svetlana and Andrey for that course!

It would be useful to add video solutions for the last task at week 5 to compare my implementation with one of the possible solutions proposed by the teacher

I really enjoyed this course. It's a very good introduction to Kotlin for those who is coming from Java. I will wait for the next, more advanced course (ideally covering coroutines, flows, arrow library etc.)

Clear visuals and explanations. Would not recommend to anyone who isn't decently familiar with Java. The integration with IntelliJ IDEA has some flaws but it is a lot nicer than having no integration at all

Отличный курс! Задачи заставили реально подумать и попотеть. Благодаря курсу, я стал лучше чувствовать смысл функционального программирования и, естественно, разбираться в работе языка Kotlin :)

Thanks JetBrains team, the course is as great as all the things that you do!

Now I am going to visit Kotlin island (Kronstadt) to see lighthouse on your logo (I leave nearby in Saint-Petersburg).

The course was very well organized. The instructor clearly explained not only the language features but also how they work under the hood. Thanks a lot, Coursera for giving me this opportunity.

This course is a great way for learning Kotlin. Although I've been using the language for almost 2 years now, still there were some new things that I've learned/re-learned from this course.

Great work, now i can understand a lot of concepts that i didn't understand before, the course is clear and very well explain with enough examples to reafirm the concept exposed, good job

Great course. I thought it was going to be a basic course and it ended being harder, in a good way! Thanks Svetlana and Andrey for putting together this course, and of course JetBrains

I learned a lot of things!!! despite I have been using kotlin in my work. The materials and explanations are really good. One of the best courses I've taken in Coursera definitely!!!

Great assignments and quizzes to go along with videos. More in-depth than any other Kotlin course I have taken with showing best practices and reasons to prefer certain patterns.

G​reat introduction to the basics of Kotlin for experienced Java programmers. Highlighted a number of features that make Kotlin a compelling alternative to straight-up Java.

Nice introduction to Kotlin language with all its crucial features. I'd be happy if I wasn't so busy and had more time for homeworks :-) Otherwise one week is sufficient.

A great course that covers perfectly the kotlin base for java developers. I was pretty excited through the whole course because it was very interesting and well teached.
