Comments in Kotlin

Comments Definition and Overview

• The text preceded by // is the single line comments in Kotlin.
• The text line from /* to */ is the traditional comment or multi-line comments in Kotlin
• Comments are neglected by Kotlin compiler.
• Comments are designed for the better understanding of code and functionality and changes in the program.

In Kotlin, there are two types of comments in Kotlin similar to C, C++, and Java.

Types

• Single Line Comments
• Multi Line Comments

Syntax

// Single Line Comment

/* 
Multi
Line
Comments 
*/

Example Program

/* Comments Example Program
   The program prints "Comments Example in kotlin" on the screen.
   Multi-line Comments
 */

fun main(args: Array<String>) {

   // prints Comments Example in kotlin - single line comments
   println("Comments Example in kotlin")

}

How It Works

This Kotlin program demonstrates Comments. It first prepares the data it needs, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
