    val bar = "World"
}

## 7. Define Arrays and write the syntax to create arrays in Kotlin.

fun main(args: Array<String>) {
    var numList = arrayOf(1, 2, 3, 4, 5)
    var emptyNumArr: Array<Int?> = arrayOfNulls(5)
    var asc = Array(5, { i -> (i * i).toString() })
}

Research and write the abstract on the following topics (Write in points)

1. History of Kotlin
+ July 20, 2011 Kotlin was announced by JetBrains, Russia.
+ 14 February 2012 Kotlin was open sourced under the Apache license version 2.0
3. What are the places Kotlin Programming language is used?
+ It is mainly used for developing Android applications, web systems, and desktop applications.
4. What is your opinion in the future of the Kotlin language?
+ Kotlin / Native has been released. I expect further success.
5. How JVM function?
+ JVMs exist on various platforms. Bytecode is generated by the compiler from code such as Java or Kotlin. The JVM does this.
