Scala class with private (and immutable) parameter

AboutClasses.scala

val aClass = new ClassWithPrivateFields("name")

    // NOTE: aClass.name is not accessible
    // Which is equivalent to the following in Java:
    //
    // public class ClassWithValParameter() {
    //
    //   private String description;
    //
    //   public ClassWithVarParameter(String description) {
    //     this.description = description;
    //   }
    // }
