Kotlin Program to Sort a Map By Values

fun main(args: Array<String>) {

    var capitals = hashMapOf<String, String>()
    capitals.put("Nepal", "Kathmandu")
    capitals.put("India", "New Delhi")
    capitals.put("United States", "Washington")
    capitals.put("England", "London")
    capitals.put("Australia", "Canberra")

    val result = capitals.toList().sortedBy { (_, value) -> value}.toMap()

    for (entry in result) {
        print("Key: " + entry.key)
        println(" Value: " + entry.value)
    }
}
 

Output:

Key: Australia Value: Canberra
Key: Nepal Value: Kathmandu
Key: England Value: London
Key: India Value: New Delhi
Key: United States Value: Washington
