Kotlin Hello World
fun main(args: Array<String>) {
println("Hello, World!")
}
Explanation:
* fun main(args: Array<String>):
* This line defines the main function, which is the entry point of the Kotlin program.
* fun is the keyword for declaring a function.
* main is the name of the function.
* args: Array<String> is the parameter of the main function, which represents an array of command-line arguments passed to the program.
* println("Hello, World!"):
* This line prints the text "Hello, World!" to the console.
* println() is a built-in function in Kotlin that prints the given string to the console and adds a newline character at the end.
To run this code:
* Save the code: Save the code in a file named HelloWorld.kt.
* Compile the code: Use the Kotlin compiler (kotlinc) to compile the code:
kotlinc HelloWorld.kt -include-runtime -d HelloWorld.jar
* Run the compiled code:
java -jar HelloWorld.jar
This will output:
Hello, World!
This is the most basic example of a Kotlin program, demonstrating the fundamental syntax and how to print output to the console.
