Kotlin Classes

Kotlin Comments:

Comments are useful, when we want to explain a piece of code, and to make it more readable.

Types of Comments:

There are two types of comments.

  • Single-line Comments
  • Multi-line Comments

Single-line Comments:

Single-line comments starts with double forward slashes ( // )
The text after these two forward slashes is ignored by Kotlin compiler (this will not be executed)
The code example below explains the single-line comment.

				
					// This is single-line comment
fun main(args: Array<String>) {
   println("Hello World!")
}

				
			

We can also add single line comment at the end of some code like the example below:

				
					fun main(args: Array<String>) {
   println("Hello World!") // This is single-line comment
}

				
			

Multi-line Comments:

Multi-line comments starts with /* and ends with */.

Any documentation between /* */ this is ignored by Kotlin compiler (this will not be executed)

The code example below explains the multi-line comment.

				
					/*This main functions prints
Hello World output It's accepting
some arguments also*/
fun main(args: Array<String>) {
   println("Hello World!")
}
