Kotlin is a modern, statically-typed programming language that runs on the Java Virtual Machine (JVM). Known for its conciseness, safety, and ease of use, Kotlin is widely used for Android development, server-side applications, and web programming. It is fully interoperable with Java, making it a great choice for developers transitioning to a more expressive and less error-prone language.

Features of Kotlin:

• Statically-typed language with type inference, making it concise yet safe.
• Fully interoperable with Java, allowing seamless integration with existing Java codebases.
• Supports functional programming features like lambdas, higher-order functions, and immutability.
• Provides null safety to prevent null pointer exceptions, a common cause of runtime crashes.
• Coroutines support for handling asynchronous tasks efficiently and concisely.
• Open-source software with an active community, ensuring continuous improvements and updates.

To check the Kotlin version:

$sudo su
$kotlin -version
