Chapter: Kotlin Last Updated: 19-11-2017 13:45:29 UTC

Program:

            /* ............... START ............... */
                
fun main(args: Array<String>) {

    var i = 1

    while (i <= 10) {
        println("Value $i")
        ++i
    }

}
                /* ............... END ............... */
        

Output

Value 1
Value 2
Value 3
Value 4
Value 5
Value 6
Value 7
Value 8
Value 9
Value 10

Notes:

• As like In Java, Kotlin while loop continually executes a block of statements while a particular condition is true.
• Test expression inside the while loop parenthesis is a Boolean expression.
• If the test expression is evaluated to true then contents inside the while loop will be executed.
• Process continues until the test expression is evaluated to false.
• If the test expression is evaluated to false while will terminate it's execution.
