Hello Scala

Start with a tiny Scala program that stores a name and prints a greeting.

Hello.scala

object Main {
  def main(args: Array[String]): Unit = {
    val name = 
    val message = "Hello, " + name + "!"

    println(message)
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val name = 
    val message = "Hello, " + name + "!"

    println(message)
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val name = 
    val message = "Hello, " + name + "!"

    println(message)
  }
}

main method A runnable Scala program can start from a `main` method inside an object.
