run object scala in databricks

Question

I am trying to execute sample code on databricks in scala. It is an object.

object Main {
  def main(args: Array[String]) {
    val res = for (a <- args) yield a.toUpperCase
    println("Arguments: " + res.toString)
  }
}

When I run on databricks; it says 'object defined main'. I am not sure how to execute it now or what is the code to execute it. Please help.

What you are working with is kind of scala REPL. Basically "main" function does not have any significance over there. Having said that you can run your function as follows

object Main {
  def main(args: Array[String]) {
    val res = for (a <- args) yield a.toUpperCase
    println(res)
    println("Arguments: " + res.toString)
  }
}

Main.main(Array("123","23123"))

As is you can call Object Main's main method.
