Who this book is for

To use this book, you should be familiar with two areas:

• You need to know Java and object-oriented programming concepts, including objects, classes, constructors, interfaces, methods, getters, setters, and generic types. So if this area does not ring a bell, it will be difficult to fully understand the rest of this book. Start instead with an introductory Java book and return to this book afterward.
• Though not mandatory, understanding the Android platform is desirable because it will help you to understand the presented examples in more detail, and you'll have a deeper understanding of the problems that are solved by Kotlin. If you are an Android developer with 6-12 months of experience, or you have created few Android applications, you'll be fine. On the other hand, if you feel comfortable with OOP concepts but your knowledge of the Android platform is limited, you will probably still be OK for most of the book.

Being open-minded and eager to learn new technologies will be very helpful. If something makes you curious or catches your attention, feel free to test it and play with it while you are reading this book
