Note, however, that the OP's code would not have been in violation of that precept if the interface had been defined:

  public interface NumList {
    void printArray();
  }

The coaching might have been phrased, "Method declarations must specify the return type, or 'void' if nothing is to be returned."

So I don't see "executable code" in the declaration, but "method defined without return type".  Either way it needs to be fixed.
