Booleans

Kotlin Tutorial

Kotlin Classes

Booleans:

The data type Boolean has only two possible values: true or false.

Example:

				
					fun main(args: Array<String>) {
   val kotlinIsBest = true;
   val kotlinIsBad = false;
   println(kotlinIsBest)
   println(kotlinIsBad)
}

The code above outputs:

true

false

Booleans are used in conditional statements (you’ll see examples of it in later chapters).
