Scala has a simple way of creating a ‘main’ method:<\/p>\n

\nobject HelloWorld { \n  def main(args: Array[String]) { \n    println(\"Hello, world!\")\n  } \n} \n<\/pre>\n

Alternately, you can extend “App”:<\/p>\n
\nobject HelloWorld extends App {\n  println(\"Hello World\")\n}\n<\/pre>\n
Note that the “main” part is done for you.<\/p>\n
