import kotlin.test.*
import java.util.*
fun main(args: Array<String>) {
//sampleStart
val map = emptyMap<String, Int>()
println("map.isEmpty() is ${map.isEmpty()}") // true
val anotherMap = mapOf<String, Int>()
// Empty maps are equal
println("map == anotherMap is ${map == anotherMap}") // true
//sampleEnd
