In the first section of the book, you will be introduced to Kotlin. You will learn how to set up your system to write your first Kotlin program and run it. This will include configuring a build system, such as Gradle or Maven, to handle dependencies used by your programs. Then, the core concepts of Kotlin, such as basic syntax for variables and values, expressions, and loops, will be explained, giving you the basic building blocks required to write a non-trivial program. In addition, the types available in Kotlin, and how nulls interact with them, will also be covered.
