how to parse an URL string to get domain only In Kotlin?

Question

I can't read Java, I need an answer in Kotlin and I have read a thread in here: Get domain name from given url

say for example I have a string like this: "http://www.myWebsite.com/profile"

then how to programmatically get the domain name only in string like this "myWebsite.com" ?

This is code from pointed question just translated to Kotlin. You can try it in Kotlin Playground.

import java.net.URI

fun main() {
    val url = "http://www.myWebsite.com/profile"
    val result = getDomainName(url)

    print(result)
}

fun getDomainName(url: String): String? {
    val uri = URI(url)
    val domain: String = uri.host
    return domain.removePrefix("www.")
}

It's much clearer to use removePrefix in this case`return domain.removePrefix("www.")` – Alexey Sviridov Jan 22 '22 at 11:22
It's not only Kotlin like requested in the question because URI is part of Java... – Crisic Jul 19 '23 at 13:45
