Introduction to Kotlin

Kotlin is a modern, statically typed programming language that is fully interoperable with Java. Developed by JetBrains, Kotlin is concise, expressive, and designed to improve developer productivity. It is widely used for Android development and server-side applications.

What is Kotlin Best Used For?

• Developing Android applications (officially supported by Google).
• Building server-side applications with frameworks like Ktor or Spring.
• Writing concise, expressive code for cross-platform applications.
• Replacing Java in existing codebases with easier-to-read syntax.

Example Kotlin Program

This example demonstrates variables, a loop, and output.

fun main() {
    // Declare variables
    val greeting = "Hello, Kotlin Programmer!"
    val count = 5

    // Display greeting
    println(greeting)

    // Loop through numbers 1 to count
    for (i in 1..count) {
        println("Iteration: $i")
    }

    // Print completion message
    println("Loop completed! Total iterations: $count")
}

Explanation:

1. Variables: greeting and count are immutable values declared with val.
2. Loop: The for loop iterates through the range 1..count. String interpolation ($variable) is used for dynamic output.
3. Output: The program prints a greeting, each iteration, and a completion message.

Sample Output:

Hello, Kotlin Programmer!
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5
Loop completed! Total iterations: 5
