Simple Scala Program - Hello World

Create, Compile and Run the Hello World Program in Scala

Scala programs can be written in a very easy manner, follow the below two steps to create, compile and run the program.

1. Open a text editor, write the following "Hello World" program and save the file with .scala extension i.e. HelloWorld.scala

Note: The file name should be the same as the class name with extension .scala - for example, if the class name is HelloWorld then the file name should be HelloWorld.scala

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

2. Compile the scala file (i.e. scala program) using the command scalac HelloWorld.scala and execute the compiled byte code using the command scala HelloWorld
