What should the format of the answer be? Just a number? also many numbers would throw an Exception which one will work?

Just a number. I'm not a Java expert so I can't comment on how many numbers would throw an exception... but if the site is not accepting your answers, have you tried compiling the code and trying them out to make sure they really do throw exceptions?

I really don't understand this problem.
2147483647 is the max integer value in java - therefore this value and every possible value above this will cause an Exception. So why isnt it accepted? If you are looking for a 'specific' integer then the challenge should say so.
Any advice?

It's asking specifically for a value for 'randomNumber', which is declared as an int, so your answer has to be a valid int. I don't think 2147483647 will cause an exception, so no, that's not the answer, and higher numbers are not valid ints, so they don't count as answers either.

The answer is a valid int.
There is only one answer and thus only one valid int that would cause an exception.

Guessing there is some trick to this? Fairly sure i have run it for everything in the range -2147483647 to 2147483647 without an error
[Edit] -Scratch That. Was Being Retarded. Can't believe i spent over an hour on something so easy and obvious!!

I've rewritten it in PHp to read it better (I'm more familiar with it).
So I have:
 |
|
<?php
function bucketFromRandom($randomNumber) {
$a = array();
for ($i = 0; $i < 10; $i++)
$a[$i] = $i * $randomNumber;
$index = abs($randomNumber) % 10;
return $a[$index];
}
echo bucketFromRandom(2147483648);
?> |
Will it work in PHP too?
And what do I have to look for? I can't get it! But maybe i just don't understand what an exception is...

Many challlenges on this site urge you to learn new things: Computer languages, cryptologic techniques, file formats.
This one is special to Java (and probably close relatives like C#). It won't work in PHP.
