About the Course

The Kotlin programming language is a modern language that gives you more power for your everyday tasks. Kotlin is concise, safe, pragmatic, and focused on interoperability with Java code. It can be used almost everywhere Java is used today: for server-side development, Android apps, and much more. Kotlin is 100% compatible with all existing Java frameworks, and has good tooling support. It’s a pragmatic language with a very low learning curve, and can be quickly grasped by Java developers. Kotlin code might be compiled not only to JVM bytecode but to JavaScript and Native code as well, but this course is focused on Kotlin/JVM. This course aims to share with you the power and the beauty of Kotlin. We'll have a basic overview of the language, as well as a discussion of many corner cases, especially concerning Java interoperability. The course is based on your Java experience; it shows the similarities between the two languages and focuses on what's going to be different. Note that this course won't cover the programming fundamentals. We'll discuss: basic syntax, nullability, functional programming with Kotlin, object-oriented programming with Kotlin, the power of the Kotlin standard library, and Java interoperability....

Excellent course, packed with relevant content and useful hands on Kotlin exercises with great feedback based on Coursera provided unit tests. Looking forward to more Coursera courses from JetBrains.

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).

It's a nice course. The exercises are very interesting and make you think on how to solve them. The material is very good, even though some concepts were very general and sometimes weren't clear. In general, It is an excellent course. I recommend it.

This was a comprehensive course focusing on the basics of the Kotlin language. The assignements were on point and helped me understand Kotlin's concepts better. I enjoyed this course, and i feel comfortable working with Kotlin after finishing it.

This is a very good course. Thanks a lot to the teachers. Good theoretical and practical material. I especially liked that for a number of tasks there is a solution from the authors. I really look forward to the release of the Corrutin course.

This course provides a look into the language and what is doing "under the hood" which is great to understand Kotlin and how to use it better. This is highly recommended for any pro developer that needs or wants to learn more bout Kotlin.

Tasks for programming was very interesting! Especially last task game2048 and fifteen. Last 2 tasks forced me to remember Math. I liked that after task was done, a saw more concise ways to do that in Kotlin.

Thanks a lot for this course!

One of the best free programming courses I've ever had. Theory + practice is excellent. Instructors are not some third parties but Kotlin creators, so they explain why each concept of the language was introduced. I like it very much!

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.

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 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.)

It's pretty much good course to get your hands on Kotlin. It deals with everything that you would need to get started with Kotlin. However it requires little knowledge of Kotlin before starting this course.

It is a very solid course.

The information is not only well structured, but also very concise yet easy to understand.

It helped me to understand better both Kotlin and Java itself.

Thanks a lot for the course!

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

Contains examples that you cannot find in other free courses - at least I didn't. Good mix of easy but not trivial and not too complex.

A bit of fun in the end: actually using the code you wrote ;-)

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