I thought answer is F but in the site it is mentioned E.

BTW source is : A question a day,i save all question so i picked up from that list while i was solving them.

[Sagar Rohankar]

I think, for this question, onc need to good at Throwable or Exception handling classes hierarchy. Here, "Error" is thrown which is subclass of "Throwable" and "Exception" is subclass of "Throwbale" but it is NOT "Error", that's why answer is E .

[Edited typo ]

Sagar,
Could you please elaborate. As per Sneha the ans is E. Whether Exception is thrown or Throwable is thrown or Error is thrown?

Edit: I AM SO SLOW

To remind you. To work with your code, one has to copy it AND delete the numbers AND replace the quotes.

For your question. An AssertionError is an Error, which is a Throwable.

Sorry, I corrected my mistake in original post, its typo. Between, I thought the last two option is pretty much confusing and not direct, its casting involved if you know this hierarchy.

  
        Throwable
               |
           --------            
        |            |
   Error         Exception

Sagar,
Its casting from Error to throwable. If there was an option saying 'An Error is thrown' then we would have chosen that.

[Sneha Kapoor]

thanks everyone...even i understood now clearly :-)

Right, Its like this AssertionError -> Error -> Exception.

Sneha,

Quoting your sources is required on JavaRanch - when you copy a question from a book, mock exam or other source, you must tell us where you copied it from. If you don't quote your sources, your question will be deleted, and if you repeatedly do not quote your sources, your account might even be locked by the administrators.

Please tell us exactly where you copied the above question from.

Using google, I am assuming you mean examulator? BTW, there are a ridiculous number of Java sources, many from blogs, and many that are not allowed on the Ranch.

Please help us as much as possible, by being as clear as possible -- as what may seem obvious to you (because you use the source) may not be as obvious to us.

Thanks,
Henry
