Kotlin is a modern, statically-typed programming language developed by JetBrains. It is fully interoperable with Java, making it a preferred language for Android development. Designed for clarity, safety and tooling support, Kotlin simplifies app development while maintaining performance and scalability.

The course begins with the fundamentals, including variables, data types, operators, and control flow statements. It then explores functions, object-oriented programming, classes, inheritance, interfaces, and abstract classes. Special attention is given to Kotlin’s unique features such as null safety, data classes, extension functions and smart casts.

Further modules cover collections, lambdas, higher-order functions, and functional programming concepts. Asynchronous programming is introduced through Kotlin coroutines. The course also includes working with files, exception handling, and unit testing.

Additional focus is placed on building Android applications using Kotlin in Android Studio. Topics include UI design, event handling, activity lifecycle, and integrating APIs. Hands-on projects and coding tasks are used throughout the course to apply concepts in practical scenarios. The course prepares for building modern, efficient, and scalable applications across mobile and server-side platforms using Kotlin.
