Getting Started with Kotlin
In this part, you will be introduced to the fundamental aspects of Kotlin, from its core syntax and basic types to its seamless interoperability with Java and the essential tools for managing Kotlin projects. You will explore how Kotlin enhances type safety with its nullability system, effectively eliminating NullPointerException issues through nullable and non-nullable types, safe calls, and the Elvis operator. Additionally, you will learn about extension functions, a powerful feature that allows you to add functionality to existing classes without modifying their source code, and the apply function, which simplifies object configuration and enhances code readability. By the end of this part, you will have a strong foundation in Kotlin’s key features, allowing you to write more concise, expressive, and maintainable code.
This part has the following chapters:
- Chapter 1, An Introduction to Kotlin and Its Basic Types
 - Chapter 2, Interoperability, Gradle, and Maven
 - Chapter 3, Null and Non-Nullable Types
 - Chapter 4, Extension Functions and the Apply Function
