Welcome to my Kotlin self-learning journey!
This repository documents my progress as I learn Kotlin — including concepts, code snippets, mini exercises, and hands-on practice.
This is a personal space to learn, experiment, make mistakes, and improve over time.
I chose Kotlin because it is a modern, concise, and developer-friendly programming language that improves productivity and code safety.
- ✅ Concise & expressive – Less boilerplate, more readable code
- 🛡 Null safety by design – Helps avoid
NullPointerException - ⚡ Modern language features – Lambdas, data classes, coroutines
- 🤝 100% interoperable with Java – Works seamlessly with existing Java code
- 📱 Official language for Android development
- 🌍 Versatile – Used for Android, backend (Ktor, Spring), multiplatform, and scripting
Kotlin strikes a strong balance between power, safety, and developer happiness, making it an excellent language to invest in long-term.
Along with Kotlin, I am also strengthening my Java fundamentals by solving Data Structures and Algorithms (DSA) problems in both Java and Kotlin.
- 🧠 Builds strong problem-solving skills
- 📚 Deepens understanding of core programming concepts
- 🔄 Helps compare Java and Kotlin implementations
- 🚀 Improves coding efficiency and interview preparation
- Understand syntax differences clearly
- Compare performance and readability
- Strengthen logic-building skills
- Master core programming concepts from two perspectives
| Feature | Java | Kotlin |
|---|---|---|
| Code verbosity | More boilerplate code | Concise and expressive |
| Null safety | Not built-in | Built-in null safety |
| Data classes | Manual implementation | Automatic with data class |
| Functional programming | Limited support | First-class support |
| Coroutines | Not available | Native coroutine support |
| Extension functions | Not supported | Fully supported |
| Android development | Older standard | Official & recommended |
