Private value of a Scala class is not accessible in the companion Object

Question

I have a Scala class and it's companion object (in Client.scala) as follows:

class Client(val key: Int) {
     private val num_bits = 5
}

object Client {
     val count_entries = Math.pow(2, num_bits).toInt
     println(count_entries)
}

However, it throws an error in the Client Object that not found: value num_bits. Could someone help?

Answer 1

You can use it like this:

class Client(val key: Int) {
     private val num_bits = 5
}

object Client {
     val count_entries = Math.pow(2, new Client(0).num_bits)
     println(count_entries)
}

You have to create the object if you want use it.
