"throw new ParityException('parity does not match');" is also valid!

Wait, can you really throw it without a message?

Agree, "throw new ParityException();" is the way to go!

I think "new ParityException();" alone won't work.

You can definitely use "throw new ParityException();" to fire it.

I’m not completely certain, but I think you need to use the throw keyword to actually fire the exception, so that makes me lean towards B and D.

I feel like we practiced something similar where we had to throw custom exceptions, and I think both B and D might be the right answers.

I think option B is definitely one way to throw the exception, but I'm a bit confused about whether option D is also correct.

I remember we discussed how to throw exceptions in our last study session, but I'm not entirely sure if option A is valid since it doesn't use the throw keyword.

I'm feeling pretty confident about this one. The two correct answers are B and D - throwing the exception with or without a custom message. I'll make sure to double-check my work, but I think I've got a good handle on how to fire this custom exception.

Hmm, I'm a little unsure about this one. I know we need to throw the exception, but I'm not sure if we need to include a message or not. I'll have to think this through carefully.

Okay, I've got this. The two ways to fire the exception are B) throw new ParityException('parity does not match'); and D) throw new ParityException();. The first one includes a custom message, while the second one just throws the exception without a message.

Hmm, I'm a bit unsure about this one. I know the severity is important, but I'm not sure exactly what goes into that assessment. I'll have to think it through carefully.

Okay, let me think this through. The key requirements are around restricting the device and application to only the necessary functionality for inventory management. I think option B, using a MAC security policy, could be a good way to achieve that.

True, so it's A and D then. A bit tricky but manageable once you think it through.

B looks correct but it has a string parameter which our custom exception doesn't handle.

Ha! I guess the developer is really into parity. Maybe they should create a 'ParityMatchException' instead. But B and D are the correct answers.

Option B is the way to go! Throwing the exception with a message is more informative for the caller.
