Top reviews from Kotlin for Java Developers

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.

This course is a very comprehensive and detailed introduction to Kotlin. However, it would be even better if it could include the generics part which is the most difficult but quite frequently used.
