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 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.

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

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

Though I'm not familiar with Java,

This course helped me to learn Kotlin.

It's a good course. I miss an explanation of how it could be possible to solve the last programming assignment.

Nicely explained.But I think its good for java developers only.Not that much beneficial for Android developers

Very good course. The only annoying part is that there are no solution videos for week 3 and 4 assignements.

Missing exercices with Kotlin/Java sources together
