About Question enthuware.ocajp.i.v7.2.864 :

[satar]

Struggled with this one because option one talks about "unexpected user inputs", which is when something out of the ordinary happens. Kind of think this one is a bit on the gray side.

[baxhuli]

Till now I knew that Exceptions were there to make sure to make the program not to crash if smth unexpected happened and not just for "logging purposes". We can log unexpected user behaviors even through "if-else if-else" but there is no other mechanism to make the program not to crash if something goes wrong. I understand that this is what Oracle wants but it does not make much sense.

[billclar]

This is a bit subjective as there are four correct answers.

Logging is a separate concept from Exceptions.
Unexpected user inputs are a reason for IllegalArgumentException.

[FruityPebbles]

I agree that the answers are somewhat subjective. You could make an argument for any of the given answers.

[admin]

Yes, it is a bit subjective and that is what the explanation says as well.

[olograph]

The only reason this question would help is:
if you haven't been warned (100 times) already that some exam questions are going to be unclear­
or
if a question with very similar syntax would show up in the exam.

Otherwise, it (re-creating potential confusing sentences) is a waste of everyone's time.

[NickWoodward]

its purpose is to recreate the exam. if that includes confusing or obscure statements, so be it.

[redvee78]

I understand what admin says about this question, but in my opinion it's a bad question. If the exam has such questions, then I personally value the exam less.

I don't understand why is this not correct:

that the VM uses to exit the program when something unexpected happens.

Based on exceptions the JVM closes the thread that is running the program. or?

[admin]

There may be multiple threads running inside a JVM. Terminating a thread doesn't mean shutting down the JVM.

[flex567]

Ok but I still don't understand why this is not a correct option?

that the VM uses to exit the program when something unexpected happens.

[admin]

because that is not what happens. Java Exceptions is NOT a mechanism that the VM uses to exit the program when something unexpected happens.
