Kotlin is a modern, statically-typed programming language designed to be fully interoperable with Java and runs on the Java Virtual Machine (JVM). Kotlin is concise, expressive, and focuses on reducing common programming errors, such as null pointer exceptions. It is widely used for Android development, backend services, and cross-platform applications.

Features of Kotlin:

• Fully interoperable with Java, allowing seamless integration with Java-based applications.
• Concise syntax that reduces boilerplate code, improving developer productivity.
• Null safety to eliminate null pointer exceptions.
• Supports both object-oriented and functional programming paradigms.
• Coroutines for efficient handling of asynchronous tasks and concurrency.
• Tooling support in popular IDEs like IntelliJ IDEA and Android Studio.
• Cross-platform development support, including mobile (Android), web (via Kotlin/JS), and native applications (via Kotlin/Native).

Run these commands:
$ sudo apt update
