This course teaches the Kotlin programming language, and progresses through to more advanced topics including Kotlin’s object-oriented nature and effectively using functions

Kotlin is the language of choice for anyone developing Android applications and is one of the most important general purpose languages on the Java Virtual Machine. In this course, Kotlin Fundamentals, you’ll learn to program in Kotlin. First, you’ll explore the fundamentals of the language such as loops, ranges, and expressions. Next, you’ll discover how to write object-oriented code using classes, interfaces, data classes, and sealed classes. Finally, you’ll learn how to use functions throughout your code, for example when working on collections and sequences and using lambdas as callbacks. When you’re finished with this course, you’ll have the skills and knowledge of Kotlin programming needed to develop Kotlin applications both on the server and on the client.
