What does the NullRobotProxyHandler class specifically concatenate to create nullName?

  1. The class name of the Robot

  2. ' NullRobot'

  3. The simple name of the type plus ' NullRobot'

  4. The full package name of the type

The correct answer is: The simple name of the type plus ' NullRobot'

The NullRobotProxyHandler class specifically concatenates the simple name of the type plus a string ' NullRobot' in order to create nullName. The class name of the Robot (A) and the full package name of the type (D) are not included in this concatenation. This is done in order to create a unique name that refers to a null instance of the robot.
