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).

This course is good if you want to learn Kotlin because it has an excellent material. The exercises are not trivial, you will spend lots of time solving them. The teacher's accent is not easy to follow.

Курс замечательный, однако, как мне показалось, многие вещи достаточно быстро проходятся и не совсем в том порядке, как было бы оптимально. В любом случае, нисколько не жалею, что прослушал данный курс.

I actually want to give 5 stars, but since the english being spoken in the video is not really clear, then 4 stars. Other than that, the course is great for any programmers who have experience in java

The assignments don't have a detailed explanation. There should be more of code provided with fill the blanks kind of tasks. This would make it much easier and helpful as the assignments are tough.

4.5 Stars.

Excellent course, some sections go out of their way to show how Kotlin is different from Java... maybe I wasn't so keen to learn about differences rather than just having fun with Kotlin.

Very useful course that covers all the basics (and more, sometimes!) of Kotlin.

It is really well-taught, but some assignments show gradle errors that can be ignored, but are still quite annoying.

It may be useful and convenient to summarize general results in the form of theoretical material under each video or topic. This would provide faster access to refresh information in your memory

Good survey of Kotlin language features. Would have been nice if assignments focused more on Kotlin idioms. Perhaps that's a fundamental issue with using an automated grader?

solid but with some annoying moments like confusing explanations. Advanced topics are not covered, and are covered in some other courses not available on coursera

I loved this course. I believe it is really useful for busy developers who want to update/upgrade their skills to now include the essentials of Kotlin language.

Language barrier makes content hard to understand sometimes. Also lots of topics that I would not want to see in production code (let or takeif, for example).

This is a great course, it introduce Kotlin very well, and show me a lot about how it works under the hood, anyway, it is a fantastic introduction course.

Есть ошибки. Немного странно изложен материал. Что-то глубоко, хотя редко пользуешься, что-то наоборот поверхностно, хотя гораздо чаще применяется.

Overall this course is a great opportunity to get a general view on the topic. However, adding some extra reading materials would be very helpful

Great but there are a few topics that require further clarification

• Lambda's with recievers

• Lambda's

• Java Collections vs Kotlin Collections

The explanation was good but not up-to mark, because the exercise which was given to us to solve was way harder than the explanation provided .

Some of the concepts are too high level for a beginner developer to learn. And the difficultly of the task should be reduced little bit.

Not all requirements in assignments are specified in the description - running tests locally and analyzing expected output is required.

Some of the lab assignments, especially in week 4 and 5 were difficult mostly because I didn't fully understand the problem domain.

Please, consider recording some videos on Second try at least, its really difficult to hear woman lector sometimes and frustrating.

I believe Svetlana can speak better, this is the only problem with course. Hope you'll find some time to rerecord better audio.

Everything is well explained, assignments are challenging but not impossible. A little lack of structure in between sections.

Некоторые задачи направлены скорее на отработку математических навыков, можно было бы больше практики с примерами решений

Though I'm not familiar with Java,

( My latest Java experience was CS101 ! )

This course helped me to learn Kotlin.
