How to get the country name from the 2-letter country code (alpha-2) in Kotlin

Answer 1

import java.util.Locale

// Function that returns the English country name for a given alpha‑2 code
fun getCountryName(code: String): String {
    // Build a Locale using the modern Locale.Builder API
    val locale = Locale.Builder()
        .setRegion(code)   // set the ISO alpha‑2 region code (e.g., "US")
        .build()

    // Return the country name in English
    return locale.getDisplayCountry(Locale.ENGLISH)
}

fun main() {
    println(getCountryName("US")) // United States
    println(getCountryName("GB")) // United Kingdom
    println(getCountryName("AU")) // Australia
}


/*
run:

United States
United Kingdom
Australia
