Kotlin- simple Java

I started to learn Kotlin. And ...
This is simple Java- said
It is used in Android- said

Reminds me... Combo Python and JavaSript. - Not need semicolon and val(var)
but It has strong type - This is good.
Example simple code:

fun main(args : Array<String>) {
    println("Hello, world!")
    val a: Int = 10000    val d: Double = 100.00    val f: Float = 100.00f    val l: Long = 1000000004    val s: Short = 10    val b: Byte = 1
    println("Your Int Value is "+a)
    println("Your Double  Value is "+d)
    println("Your Float Value is "+f)
    println("Your Long Value is "+l)
    println("Your Short Value is "+s)
    println("Your Byte Value is "+b)
}
