whitch one is faster?
Exception Handling should be used for only handling "exceptional" situations. What you have mentioned can be done by performing appropriate validations on Input
catch(ArithmaticExeption a){
}
catch(IndexOutOfBoundsExeption a){
}
Yes its perfectly fine to have both variables named "a", because "a" is visible only inside the corresponding catch blocks and not outside of them. It wouldn't have killed you to just compile a program with the above situation, if it was incorrect at most you would have received a compile error.
