Why do I get java.lang.NoClassDefFoundError when I trying to run this code?

Question

I want to map over the characters in a string, but I\'m getting runtime errors.

Example:

object Hello {
    def hello(c: Char) {
        print(c)
    }

Also seeing this problem because I don't have the right version of Scala. For those who are using IntelliJ, you can add/change the scala SDK under File > Project Structures > Global Libraries:

If you are compiling and running your project in command line, make sure you have the right version of Scala installed too. e.g.:

Check the Scala version installed:

$ scala -version
Scala code runner version 2.11.8 -- Copyright 2002-2016, LAMP/EPFL

Check the build.sbt to have the right version of Scala:

scalaVersion := "2.11.8"
