Kotlin Comments

Comments

• Comments can be used to explain kotlin code.
• Comments can be used to make code more readable.
• Comments are ignored by kotlin Compiler
• It can also to be used to prevent execution whem testing alternaive code.

---

Single-Line Comments

• Single line comments start with two forword slashes (//)
• Code between two forward slashes will ignored by kotlin compiler.

Example

//this is comment
println("hello world")

Multi-Line Comments

• Multi-line comments start with /* and ends with */
• Code between /* and */ will ignored by kotlin compiler.

Example

/* this is
multi line
comment
*/
println("Hello world")

Following example shows if you want to prevent specific line to execute you can use comments thier.

Example

println("First")
//println("Second")
println("Third")
//println("Fourth")
//println("Sixth")
println("Seventh")
//println("Eighth")
println("Ninth")
println("Tenth")

Above example only prinln "First Third Seventh Ninth Tenth" because other line are become code they does not executes.
