Kotlin Online Test

Kotlin is a programming language introduced by JetBrains, the official designer of the most intelligent Java IDE, named Intellij IDEA. Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. The most strongly supported JVM language in the Android ecosystem—aside from Java—is Kotlin. Kotlin language is designed to interoperate fully with the Java platform, and the JVM version of its standard library mainly depends on the Java Class Library. Kotlin also uses libraries for Android and browsers.

    GlobalScope.launch {
    println ("0")
    delay(1000L)
    println("1, 2, 3")

    println("4, 5, 6")
    Thread.sleep(2000L)
    println("9")
}
