Two things:

1. The file you’re working with must be a Scala class.

2. You should have an object declared somewhere (preferably outside of the class).

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

You can then use this object to run your Scala code in IntelliJ.
