Kotlin is a modern programming language developed by JetBrains. It is designed to be concise, expressive, and interoperable with existing Java code. Kotlin can be used for various purposes, including mobile app development (Android), server-side development, web development, and even native development using Kotlin/Native.
To start using Kotlin, you need to have the Kotlin compiler installed on your system. You can download it from the official Kotlin website (kotlinlang.org). Once installed, you can write Kotlin code in any text editor or use an Integrated Development Environment (IDE) like IntelliJ IDEA, Android Studio, or Eclipse with Kotlin plugins.
Here's a simple "Hello, World!" program written in Kotlin:
```kotlin
fun main() {
println("Hello, World!")
}
```
You can save this code in a file with the ".kt" extension (e.g., `HelloWorld.kt`). To compile and run the code, you can use the Kotlin compiler by running the following command:
```
kotlinc HelloWorld.kt -include-runtime -d HelloWorld.jar
```
This will generate a JAR file (`HelloWorld.jar`). You can then run the program using the Java Virtual Machine (JVM) like this:
```
java -jar HelloWorld.jar
```
This is just a basic example to get you started. Kotlin has many advanced features and capabilities that make it a powerful and flexible language to work with.
