Kotlin Tutorial
This Kotlin tutorial is designed for beginners as well as professional, which covers basic and advanced concepts of Kotlin programming language.
In This free Kotlin tutorial, you’ll learn various important Kotlin topics, including data types, control flow, functions, object-oriented programming, collections, and more. We will also delve into advanced concepts such as Kotlin coroutines, null safety, and functional programming in Kotlin.
Prerequisites for Kotlin Tutorial
To get started with Kotlin, it’s helpful to have a foundation in several key areas. Here are the primary prerequisites for beginners:
- Basic Understanding of Java: Kotlin is designed to be compatible with Java, so having a basic understanding of Java programming language is recommended.
- Programming Environment: Familiarity with any programming environment is assumed.
- Basic Concepts: Knowledge of basic concepts such as variables, commands, syntax, etc. is assumed.
- Basic Understanding of IDEs: Familiarity with Integrated Development Environments (IDEs) like IntelliJ IDEA or Android Studio will help you navigate and use these tools effectively.
What is Kotlin?
Kotlin is a modern programming language created by JetBrains, in 2011 the same company behind the popular IntelliJ IDEA. It runs on the Java Virtual Machine (JVM) and can also be compiled to JavaScript or native code. Kotlin is an object-oriented language, and a “better language” than Java, but still be fully interoperable with Java code. Kotlin is sponsored by Google, announced as one of the official languages for Android Development in 2017.
Why Kotlin for Android Development?
- Google Support: Kotlin is officially supported by Google for Android development, ensuring it works well with Android Studio.
- Easy to Read and Write: Kotlin’s code is shorter and clearer than Java, making it easier to understand and work with.
- Works with Java: Kotlin can be used with Java in the same project, making it easy to switch from Java to Kotlin.
- Null Safety: Kotlin helps avoid errors by clearly handling null values, which are a common source of bugs in Java.
- Better Asynchronous Code: Kotlin’s coroutines make it easier to handle background tasks like network requests without blocking the app.
- Strong Community: Kotlin has a growing number of libraries, tools, and community resources to support developers.
