Ok, i got myself answer. You can use auxiliary constructors, if your
defining an auxilary constructor you need to use the primary constructor.

Hi,
Does this snippet from the Scala REPL help?

scala> class C(i: Int, s: String) { def this(n: Int) = this(n, "boo!") }
defined class C

scala> val x = new C(7)
x: C = C@2598a35d

scala> val y = new C(7, "blah!")
y: C = C@7844a013
