Quickly master Kotlin by practicing what you learn KEY FEATURES ● Understand Kotlin concepts and best practices. ● Apply what you learn in eight engaging interactive projects. ● Build real-world applications, including REST APIs and serverless deployments. DESCRIPTION Kotlin Crash Course is a fast-paced, hands-on introduction to Kotlin, preparing readers to build robust applications efficiently using the latest language features and best practices. The book is divided into comprehensive chapters that cover key Kotlin programming topics such as object-oriented and functional programming, collections, concurrency, and unit testing. Each chapter takes a learning by doing approach, focusing on practical projects rather than solely theoretical knowledge. This strategy improves knowledge retention by simulating real-life experiences, allowing students to apply concepts in practice as they learn them. Furthermore, the book is interwoven with an abundance of best practices obtained from industry experience. This approach ensures that even beginners can gain seasoned insights and apply their knowledge confidently to real-world challenges. By the end of this comprehensive course, you will not only possess a strong foundation in Kotlin programming but also the practical skills to build real-world applications, including REST APIs and serverless applications leveraging Kotlin's cloud capabilities. WHAT YOU WILL LEARN ● Understand Kotlin syntax and basic coding conventions. ● Master object-oriented and functional programming concepts. ● Utilize Kotlin’s collection framework effectively. ● Implement concurrency and parallelism with coroutines. ● Build robust applications with best practices. ● Develop diverse applications, including REST APIs and serverless solutions. WHO THIS BOOK IS FOR This book is suitable for students, programmers from other languages, Java developers, back-end developers, full-stack developers, and mobile developers. The book is appropriate for both new and experienced programmers wishing to acquire or refresh their Kotlin skills. TABLE OF CONTENTS 1. Discovering the Power of Kotlin Programming 2.

Kotlin 2.0 Crash Course
If you're looking to write responsive Android and web applications using Kotlin 2.0, this book's got you covered with some great examples. In the early chapters, you'll dive into the basics of variables, data types, and control structures like if-else, when, while, and do-while. There's a chapter on functions that'll teach you to write reusable code, use higher-order functions, and adopt lambda expressions to streamline operations in the project. As you move into object-oriented constructs, you'll learn to define classes, primary and secondary constructors, inheritance, interfaces, and encapsulation practices that keep internal task details safe and modular. Then, we'll dive into collection handling, where we'll use lists, arrays, sets, and maps along with some handy code that'll filter, transform, and iterate through tasks. In the state management section, you'll see how immutable snapshots and mutable services work together using observers to sync components in real time. The chapters on functional programming will walk you through chaining, mapping, and flattening data pipelines. The error handling and type casting chapters will show you how to catch and log exceptions, apply safe casts, and recover from unexpected conditions without crashing. If one wants to get really into JSON serialization, it's possible to learn how to parse JSON into Kotlin objects, serialize tasks back into JSON, and use libraries like kotlinx.serialization or Moshi for nested structures. Finally, Ktor integration teaches you to initialize a coroutine-based server, define routes, install middleware, secure endpoints with authentication, and test your components thoroughly. This book won't turn you into a Kotlin master overnight, but it'll give you the confidence and hands-on experience you need to build real-world Android and web apps with Kotlin 2.0 right from the start. Key Learnings Build strong foundation in Kotlin 2.0 syntax to write clear, concise code. Absorb strong designing principles including classes, constructors, inheritance, and encapsulation for robust design. Gain practical mastery in using lists, arrays, sets, and maps to store, filter, and transform the data efficiently. Strong hold on coroutine-based state management and observer patterns for responsive, synchronized application behavior. Develop fluency in functional programming alongwith lambdas to process data pipelines succinctly. Perform JSON parsing and serialization using kotlinx.serialization, Moshi, and Jackson. Practical implementation of Ktor’s routing, plugins, middleware, and testing for web server development. Streamlined testing and debugging workflow, combining in-memory tests, logging, and profiling to catch issues. Table of Content Up and Running with Kotlin 2.0 Variables, Data Types, and Basic Operations Control Structures and Program Flow Functions and Modular Programming Techniques Object-Oriented Constructs and Class Design Collection Handling and Iteration Patterns Managing Application State and Behavior Functional Programming with Lambdas Error Handling and Type Casting Handling JSON and Data Serialization Designing RESTful API Building Web Server with Ktor
