Bug in the last exercise of chapter 2.7 about spinal-bootcamp HOT 4 CLOSED

@AlkaidDoge sorry, my fault, the old example is out of date. The new implementation has been updated in e754d5e

from spinal-bootcamp.

@jijingg Thank you very much for your timely repair, but I had a little problem running the new implementation.
I copy your code into Intellij IDEA, then it tell me "protected" modifier is no allowed here.But I can run code in jupyter,why?
(Although I take out "protected" and it works....)

protected object CommonCellBlackBox {
    private var _clear: Boolean = false
    def clear: Boolean = _clear
    def clear_=(x: Boolean) { _clear = x}
  }

from spinal-bootcamp.

@AlkaidDoge protected is not necessary here , but in the lib CommonCellBlackBox is not need open for Users， so i limit it's scope.
It depends on your design.

package object commonCell {
.....
  protected[commonCell] object CommonCellBlackBox {
    private var _clear: Boolean = false
    def clear: Boolean = _clear
    def clear_=(x: Boolean) { _clear = x}
  }

  object clearCCBB{
    def apply() = CommonCellBlackBox.clear = true
  }
}

Okay.Thank you for your answer. I don't have any questions. : )
