fun main(arg: Array<String>) {

    //Input Stream
    val sc = Scanner(System.`in`)

    //Input Decimal Number
    println("Enter Decimal Number  : ")
    var decimalNumber: Int = sc.nextInt()

    var octalNumber = 0
    var i = 1

    //Convert Decimal to Octal
    while (decimalNumber > 0) {
        val r= decimalNumber % 8
        octalNumber += r * i
        decimalNumber /= 8
        i *= 10
    }

    //Print Octal Number
    println("Octal is : $octalNumber")
}

Output

Run 1:
