scala - Why are constructor parameters made into members for case classes? -

  {       class myclass(name: string) {}        val x = new myclass("x")       println(x.name)         // error name not member of myclass   } 

but

  {       abstract class base        case class myclass(name: string) extends base {}        var x = new myclass("x")       println(x.name)           // name member of myclass   } 

so, what's deal case classes? why of constructor parameters turned variables.

name member in both examples, private in first example while public in second. case classes make constructor parameters public val default.
