Question

I have a scala class:

class Foo {

  def this(st: String) {
      var baz = List[String]()
      var jaz = "one" + st
      // more code logic


  }

} 

First above code does not compile. Secondly I want baz and jaz to be private variables local to the lone constructor above and not instance variables.

How to solve this problem?

Answer 1

It does not compile because the first thing that MUST happen in an auxiliary constructor is a call to the primary constructor. I don’t understand the second question, since the variables you have declared already ARE private
