Convert char to its ASCII code in Kotlin

This article explores different ways to convert a char to its ASCII code in Kotlin.

A simple solution to convert a char to its ASCII code is using the toInt() function, which returns the value of the character as an Int. Here’s a Kotlin program demonstrating its usage:

fun main() {

val c = 'x'

val ascii = c.toInt()

println(ascii) // 120

}

Alternatively, we can get the value of this character as a Byte and convert this Byte value to Int:

fun main() {

val c = 'b'

val ascii = c.toByte().toInt()

println(ascii) // 98

}

To convert each character of a string to its ASCII code, we can encode the string into a sequence of bytes using the getBytes() function, resulting in a new byte array. The following code example shows invocation for this method:

fun main() {

val s = "Kotlin"

val bytes = s.toByteArray()

println(bytes.contentToString()) // [75, 111, 116, 108, 105, 110]

}
