Kotlin for Beginners: Complete Course

The book "Kotlin for Beginners: Complete Course" is a practical guide that will take you from the very basics to creating your first full-fledged applications in the modern Kotlin language. Regardless of whether you have experience in other languages or are just starting your journey in IT, this course will help you confidently master the syntax, logic, and ecosystem of Kotlin.

Who is this book for?

• Beginners who want to learn programming from scratch in a modern and in-demand language.
• Developers transitioning from Java or other languages who want to quickly learn Kotlin.
• Students and self-learners looking for structured and understandable material with examples.

What will you learn from the book?

• Basics of syntax: variables, data types, conditional statements, and loops.
• Object-oriented programming (OOP): classes, objects, inheritance, interfaces, and polymorphism.
• Functional programming in Kotlin: lambdas, higher-order functions, working with collections via filter, map, reduce.
• Working with null safety — one of the key features of the language.
• Creating console applications and simple utilities.
• Basics of working with files, exceptions, and the Kotlin standard library.

Each chapter contains a theoretical block, clear code examples, and practical tasks to reinforce the material. By the end of the book, you will be able to write simple programs on your own, understand other people's code, and be ready to study more complex topics: Android development, coroutines, or server-side programming with Ktor.

Kotlin is the official language for Android, actively used in backend development and Data Science. Start your programming journey with the right choice!
