#Kotlin Programming Language Tutorial

#Overview

Kotlin is a modern, statically typed programming language developed by JetBrains. It is 100% interoperable with Java and can run on JVM, Android, browser, and native platforms. Kotlin is known for its concise syntax, null safety features, and powerful coroutine support.

#Learning Objectives

Through this tutorial, you will learn:

• Kotlin basic syntax and core concepts
• Object-oriented and functional programming features
• Null safety and type inference
• Coroutines and asynchronous programming
• Interoperability with Java
• Android development basics
• Using Kotlin standard library

#Prerequisites

• Basic understanding of programming concepts
• Familiarity with object-oriented programming (recommended)
• Java knowledge (helpful for understanding interoperability)
