Hello World in a Scala Notebook

This notebook is a first try with a Scala (Spark) kernel. Please be patient on execution of the first cell, it takes a little bit to get the kernel moving.

We can create a Scala program:



In [ ]:

    
object HelloWorld {
  def main(args: Array[String]) {
    println("Hello, world!")
  }
}

.. and execute it



In [ ]:

    
HelloWorld.main(null)

... but since this is a REPL environment, it is actually simpler to just start executing Scala code



In [ ]:

    
println( "Hello world" )

If you reached here without problems, it means the Scala kernel works.
