Scala, importing class

问题:

I have two files:

logic.scala and main.scala

logic.scala contains one class and main.scala have one class with method main (to run it). And I want to import a class from logic.scala and use this class to create object(s) and work with them.
How to import and compile it in proper way?

回答1:

• logic.scala code

package logic

class Logic{

  def hello = "hello"

}

• main.scala code

package runtime

import logic.Logic  // import

object Main extends Application{

  println(new Logic hello) // instantiation and invocation

}

• compile the files with scalac

scalac *.scala

• run your application with scala

scala -cp . runtime.Main
