Building Kotlin Applications

Kotlin is a modern, expressive, and concise programming language popular among developers for its many benefits. These include its interoperability with Java, ability to build native mobile and web applications, and support for functional programming.

This book provides a comprehensive introduction to Kotlin, covering everything you need to know to start building Kotlin applications, regardless of your prior programming experience.

You'll start by learning the basics of Kotlin, including its variables, types, functions, and control flow statements. Then, you'll explore more advanced topics such as object-oriented programming, generics, coroutines, RxKotlin, and multiplatform development. Once you have a solid foundation in Kotlin, you'll learn how to use it to build real-world applications. You'll start with a simple Android application and then move on to more complex projects, such as a web application and a desktop application.

By the end of this book, you will have a deep understanding of Kotlin and be confident in your ability to use it to build robust, maintainable, and scalable applications.

KEY FEATURES  

• Understand Kotlin fundamentals, such as syntax, type system, basic concepts, and reactive programming principles.
• Learn to use Kotlin's advanced features, such as coroutines, extension functions, and generics, to write efficient, maintainable, and reusable code.
• Explore applying reactive programming techniques to solve common challenges, such as handling concurrency, managing data streams, and building responsive user interfaces.
• Seek guidance on how to build robust and scalable applications using Kotlin and reactive programming patterns, such as Spring Boot.

WHAT YOU WILL LEARN
