Kotlin is a modern JVM language for enterprise applications, Android development, and backend services. It is designed to reduce boilerplate, improve safety, and interoperate with the Java ecosystem. Its practical strength is simple code with strong tooling and a broad ecosystem.
| # | KOTLIN | Topic | Description |
|---|---|---|---|
| PHASE 1: LANGUAGE BASICS | |||
| 01 | Foundations | What Kotlin is, where it is used, and how it fits into the JVM ecosystem. | |
| 02 | Environment | Install the JDK and Kotlin tooling, then set up a clean editor workflow. | |
| 03 | Syntax | Program structure, expressions, declarations, and Kotlin source rules. | |
| 04 | Types | Type inference, values, arrays, strings, and numeric modeling. | |
| 05 | Control | Branches, loops, ranges, and Kotlin control expressions. | |
| PHASE 2: PROGRAM STRUCTURE | |||
| 06 | Functions | Parameters, default values, named arguments, lambdas, and extension functions. | |
| 07 | Collections | Lists, maps, sets, immutability, and collection operations. | |
| 08 | Classes | Classes, data classes, sealed types, inheritance, and interfaces. | |
| 09 | Null Safety | Nullable types, safe calls, Elvis, and defensive Kotlin design. | |
| 10 | Coroutines | Suspend functions, async workflows, and structured concurrency. | |
| PHASE 3: DELIVERY AND DEPTH | |||
| 11 | Architecture | Layered and feature-based Kotlin application structure for JVM, Android, and backend work. | |
| 12 | References | Official docs, tools, JVM guides, architecture references, and deeper study paths. | |
