In java code, original answer only please. If you copy and paste from another question I will downvote. I mainly am having issues with the PowerOut and WindowMalfunction events, and how to make the controller catch the exception. Thanks!

1. Create a WindowMalfunction and PowerOut Events to simulate problems that may occur in a GreenhouseControls. The event should set the following boolean variables as appropriate in GreenhouseControls:

• windowok = false;

  poweron = false;

  After setting the variables, WindowMalfunction or PowerOut should throw an exception specifying the faulty condition. Create a ControllerException class that extends Exception for this purpose.

2. If an exception is thrown from WindowMalfunction or PowerOut, the Controller catches the exception, then initiates an emergency shutdown with an appropriate message. Add a method to Controller called shutdown, and override this method in GreenhouseControls to accomplish the shutdown.

3. Add an instance variable in GreenhouseControls called errorcode. It indicates the nature of the problem with an error code in an int variable errorcode (1 for WindowMalfunction and 2 for PowerOut), logs the time and the reason for the shutdown in a text file in the current directory called error.log and prints it to the console. It then serializes and saves the entire GreenhouseControls object in a file dump.out in the current directory before exiting.
