Kotlin – Check if given number is even

In this tutorial, you shall learn how to write a program to check if given number is an even number in Kotlin.

Kotlin – Even Number Program

To check if given number is even or not in Kotlin, divide the given number by 2 and check the remainder. If the remainder is zero, then the given number is an even number, else not.

If n is the given number, then the condition to check if n is even or not is

n % 2 == 0

The above expression returns true if n is even, or else it returns false.

Program

In the following program, we take a number in n, and check if it is even number or not using the above condition.

Main.kt

fun main() {
    print("Enter an integer : ")
    val n = readLine()!!.toInt()
    if (n % 2 == 0) {
        println("$n is even.")
    } else {
        println("$n is not even.")
    }
}

Output #1

Enter an integer : 8
8 is even.

Output #2

Enter an integer : 5
5 is not even.
