A beginner-friendly repository to help you learn the Kotlin programming language — covering the fundamentals with hands-on examples.
Kotlin is a modern, statically typed programming language developed by JetBrains. It’s fully interoperable with Java, concise, expressive, and officially supported for Android development by Google.
- Install IntelliJ IDEA (Community Edition is free):
https://www.jetbrains.com/idea/download/ - Create a new Kotlin project: File → New → Project → Kotlin → JVM.
- Alternatively, use the Kotlin Playground or install the Kotlin plugin in VS Code.
- Create a Kotlin file with:
fun main() { println("Hello, Kotlin!") }
- Run it—if you see
Hello, Kotlin!
in the console, everything’s ready.
- Kotlin Syntax and Structure
- Variables and Data Types
- Operators and Expressions
- Control Flow (if, when, loops)
- Functions and Lambdas
- Object-Oriented Programming (Classes, Inheritance)
- Collections & Functional APIs
- Null Safety and Exception Handling
